The new addition of LAN support enables its use with PCs as a recording instrument suitable for the Internet age. It comes with a rich product lineup as input unit for measuring different types of signals. You can select a type most suitable for your needs.

Example of using measurement data in Excel Dial Knob with Analog Sensibility! Easy-to-use 16-channel Recorder. With a conventional pen recorder, even if all test data is written on the paper, usually only a small portion of the data is needed. However, to look for just a small important part requires very extensive search of the recording paper. MEMORY HiCORDER 8841, 8842 stores and manages all waveform measurement data electronically. Furthermore, use of a LAN card and LAN COMMUNICATOR 9333 enables high-speed data file transfer to PCs on a ne-twork. A LAN-Connectable Recorder! Digitally Process Test Data - Features -

• Large-capacity memory In the standard memory configuration, a total of 8 mega-words can be stored. With expansion memory installed, capacity is a full 32 mega-words. This provides for up to 2 mega-words per channel when 16 channels are used. Even with high-speed sampling, long-term recording is possible.
• 10.4 inch color TFT display for easy visual identification The color display makes it easier to identify waveforms and eases installation of devices, and makes the unit all the more easier to operate.

Monitors non-visual (mechanical or electrical) operations and provides support to solving problems - Application - Research and development of automobiles (8841) In vehicle and engine running tests, the relationship among various parameters must be examined. Multi-channel recorders are necessary to accomplish this. While 8841 has retained the size of its predecessor, the 8840, it allows recording with 16 analog channels + 16 logic channels. Using the DC POWER ADAPTER 9433 enables operation using the vehicle's battery (+12 V/+24 V). * With the 4ch ANALOG UNIT 8946 (4-channel unit) attached. Evaluation of machines and materials Pressure waveforms can be measured and recorded simultaneously at various points of hydraulic machines to determine whether such machines are operating normally. Using, for example, the recorder's X-Y recording function, performance dispersion check can be conducted by recording the relationship between one cycle operation command signal for an injection molding machine, the pressure and the position change. ■ Engine tuning Allows the balance between boost, oil pressure, air fuel ratio, ignition timing, engine speed, injector aperture, etc., to be observed and recorded as waveforms. ■ Analysis of engine characteristics The pressure waveforms of injection pipes and fuel- injection pumps, etc., can be recorded and stored in the internal memory and then superimposed on a reference waveform for analysis. ■ Evaluation of electrical circuits Quality evaluation of meter boards for use in automobiles can be performed by recording and evaluating analog waveforms. Waveform judgment After defining a reference waveform bounding area, it is possible to check whether waveforms go outside this reference area. As opposed to simple voltage level- based triggering, even complex waveforms can be evaluated quickly and reliably, because both the level direction and the time axis direction are taken into consideration simultaneously. * Registered patent no. 2028013, in Japan ■ Analysis of injection molding machine operation The quality of molded products can be evaluated by recording the relationship between the injection molding machine's operation command and the pressure and position change. ■ Analysis of tensile tests When conducting stretching characteristic test and tensile test of steel tubing, the relationship between load and contraction can be recorded. ■ Recording of motor rush current The rush current occurring when the power to a motor or a relay is turned on can be accurately measured as a waveform. ■ Servo-controller analysis The operation of a servo-controller utilizing a PWM inverter and used to control a general motor can be accurately measured as a waveform. Recorder function X-Y display The recording time is unlimited in the case of recording an X-Y plot of two analog channels. The channel combination is arbitrary. The X-Y plot can be viewed on the screen, and it can also be printed out as many times as desired, making this more useful than what is offered by standard X-Y recorders. Fast response recorder function The 8841 and 8842 have a recording function which can print out data onto paper in real-time. Recording continues until the recording paper (30 m per roll) is used up. The recorder functions offered by the 8841 and 8842 outperform others in the way that the recorder's pen response is extremely fast in relation to the sampling speed. The maximum sampling speed is 1 µs, which is the same as the memory recorder function speed.

Load shutdown tests in power generation plants and inspection of electric systems For load shutdown tests in power generation plants, the pre-trigger function can be used to measure and record waveforms before and after the test, enabling accurate analysis. The vernier function, which can be used to perform fine adjustment of amplitudes, is also a useful tool. In the field of electricity, the recorders have many applications, such as recording of rush current frequency, recording of breaker activation timing, and monitoring of power lines for irregularities. Vibration analysis When installing rotating machinery, such as agitators, that create many vibrations, damping precautions are normally taken to ensure that the vibrations are not propagated directly to the floor surface. Analysis of the vibration damping measures and effects can be conducted by measuring the natural frequency and the transfer function. - Application - ■ Measurement of the damping of vibrations reaching the solid base from the rotating machinery By striking the agitator with an impulse hammer, the vibrations propagated to the solid base can be measured by the acceleration speed pick up. Finding the transfer function can show to what extent specific frequencies are being dampened. ■ Measurement of the natural frequency of objects Resonance phenomena can be avoided by ensuring that the natural frequency of an object is different from the vibration frequency of the surroundings. By striking the object with an impulse hammer and finding the transfer function, the natural frequency of the object can be found. FFT analysis function FFT capability includes single-signal FFT for analyzing frequency components, two-signal FFT for transfer function analysis, and octave analysis for acoustic analysis. The source signal can be selected from waveform data captured by the memory recorder, and isolating required sections is also possible. (Number of data points: 1000 - 10000) Rotation frequency ■ Load shutdown test Analysis of the relationship between the generator voltage, rotation speed regulation, governor servo operation condition, and the open and close timing of the pressure regulator before and after load shutdown can be performed. ■ CB timing measurement For inspection of the shutdown timing of circuit breakers for electrical circuits, the relations between logic signals and analog waveforms of multiple points can be analyzed. close command Phase R Phase S Phase T Memory recorder function The input signal is converted to digital form and stored in the internal memory. It can then be displayed on the screen or printed out on paper. Since the recordable signal speed is determined by the sampling rate and the memory saving rate, it is simple to capture even very fast transient events that escape normal recorders. All channel inputs isolated Each channel has its own dedicated A/D converter, allowing simultaneous sampling in all 16 analog channels and in all 16 logic channels. ■ Momentary loss of power recording Momentary loss of power in power-supply circuits can be recorded by using the voltage drop detection trigger, thus enabling accurate waveform recording of unexpected events. ■ Ground fault line detection To identify the ground fault line of transmission lines, measurement can be conducted using the trigger that combines a leak current meter and the recorder. This allows observation and recording of the waveform before and after ground faulting to identify the line. RMS recorder function This function is exclusively for use on 50/60 Hz power- supply lines and DC. High-speed sampling is applied to calculate the rms value from the waveform data, and the result is recorded as a graph. *Using 200 μs high-speed sampling, data for two waveforms are captured for calculating the rms value. This process is repeated 20 times per second, resulting in high-speed response that is 10 times faster than that of a digital tester or similar (using a 2-second update rate).Chart of Recorder function Chart of RMS recorder function

High-Speed Response for Capturing Transient Events - Function Details - ■ Zoom function *In memory recorder function To make the most of the large-capacity memory, it is possible to display a compressed waveform simultaneously with a magnified waveform. Since the 8841 and 8842 are capable of storing a large amount of data, high-speed sampling is also possible for waveforms with a long duration. Accordingly, while observing the compressed image of the entire waveform, it is also possible to observe the magnified details of desired parts. Compressed display of a part of the entire waveform is also possible. ■ Clock input for external sampling *In memory recorder function The sampling rate for the memory recorder can be controlled by the timing of an external clock signal. This is useful for example to collect data synchronized to the running cycle of an engine. Recording length using 16 channels Segmentation into 3 blocks Segmentation into 127 blocks Segmentation In the standard configuration, the 8841 and 8842 can store a total of 8 mega-words, and with memory expansion 32 mega- words, using internal solid-state memory. This provides ample capacity to store data for all 16 channels. The table at right shows possible recording times, according to the time axis setting and the number of channels in use. A reduction in the number of channels prolongs the recording time.

When the optional MEMORY BOARD 9608 is installed, recording times are extended by a factor of 4 (from 16 mega-words/channel, 160,000 divisions for 2 channels to 2 mega-words/channel, 20,000 divisions for 16 channels). ■ Memory segmentation function When using the memory recorder function, the data memory can be divided into a maximum of 255 blocks. Data can be written sequentially to the memory blocks, and the waveform in a reference block and any other block can be superimposed and compared. * In the standard memory configuration (8 mega-words), the maximum number of blocks using the 16 channel setting is 127. When the memory expansion is installed, or when the channel setting is 2 to 8, the maximum number of blocks is 255.

• Function Details - Support for connection to PCs via Ethernet 8841/8842 can be connected to Ethernet, a standard network protocol in the Internet age (using the optional LAN CARD and LAN COMMUNICATOR 9333). For those who frequently analyse measurement data on PCs, this function offers a good match. Also, connection to PCs using RS-232C connection or GP-IB connection is possible (using the optional RS-232C CARD 9557 and GP-IB CARD 9558). 8841/8842 data can be sent to PCs or be remotely controlled from PCs. * Because LAN card, GP-IB card, and RS-232C card all use the same PC card slot of 8841/8842, when one of them is inserted into the PC card slot, then any memory card cannot be used at the same time. ■ Connect HiCORDER to departmental LAN (using TCP/IP communication protocol) ■ Save data to network server (using TCP/IP communication protocol) Copy measurement data files obtained from HiCORDER to PC on network PC running 9333 (software) Offline data exchange with PCs The supplied waveform viewer (PC application) can convert saved waveform data to text files (CSV format). For data storage, FD/PC card (supplied as standard) can be used. This allows easy offline data exchange with PCs. Memory / main unit Memory / main unit Memory / main unit * In addition to HiCORDER 's read/write native file (binary format), data can also be saved to text files (CSV format) which can be opened by PC spreadsheet applications, or waveform bitmap files (BMP format). However, because data saved in text files cannot be read by HiCORDER , it is recommended that text data conversion be performed on PCs. Color image output to the network printer Copy or remote operations of HiCORDER data files from client PCs running 9333 (software) Ethernet Floppy disk Flash ATA PC card Input Voltage Approx. Display Vernier Scaling Variable Scaling Functions Actual measurements usually involve parameters other than voltage. Various physical parameters such as speed, vibration and temperature commonly need to be recorded, and this signal data should be directly readable, without having to be manually converted. In such measurement conditions, the scaling function can be used to automatically convert to the desired parameter value. Additionally, waveform amplitude can be adjusted using the Variable Gain function. In addition, if accurate input voltage amplitude measurement is not required, the amplitude can be intentionally modified with the Vernier Adjustment function.

Display data (REC waveform): compressed waveform is displayed on screen Compressed data is saved temporarily in the internal memory. However, display time axis of REC data is 2 steps later than that of MEM data. The maximum recording time that can be set is determined by the free capacity of the PC card, and the time axis and recording length of MEM/REC. Nevertheless, since the maximum recording length of REC is fixed at 1000 DIV , or 5000 DIV if there is memory expansion, even if there is plenty of free capacity on the PC card, the recording time cannot exceed the value determined by REC time axis multiplied by 1000 DIV . - Function Details - Real time save function *supported in version 2.60 or later The real time save function enables data to be saved to the PC card while waveform is being measured. The compressed waveform is displayed on the screen at real time. This function is valid at the recorder and memory function. Write to the PC card can be up to 2kS/s (=50ms/DIV) for 8 channels, or up to 1kS/s (100ms/ DIV) for 16 channels. With the real time save function, data measured at the pre-determined sampling below the maximum sampling can be saved to the PC card at any time. In addition, since the same data is compressed along the time axis and displayed on the screen, you can check how recording is going. Compressed data is saved to the PC card for later retrieval.

Note: Maximum continuous recording time at MEM function, with time axis is 1 hour/DIV in REC function. Note: Limit of maximum continuous recording time at MEM function is 208 days and 8 hours. Storage data (REC waveform) : Save compressed data to the PC card after measurement Time axis setting(REC): 200 ms/DIV to 1 hour/DIV (sampling frequency starting from 2 kS/s for 8 channels or from 1 kS/s for 16 channels) Recording length setting (REC): up to 1000 DIV (or up to 5000 DIV with memory expansion) Trigger functions capable of monitoring all 16 channels For all of the measurement functions, including record and memory recorder, triggers can be set on all 16 channels. In addition to a simple level trigger based on comparison with a single voltage value, the following trigger functions are also available:

• Window trigger based on 2 voltage values
• Voltage drop trigger for AC power lines
• Level trigger based on rms values
• Cycle trigger monitoring the rising edge of a voltage
• Pattern trigger monitoring the Hi/Low condition of a logic signal

As illustrated by the picture on the front page, overlapping recording is also possible. ■ Online help and error indication Simply pressing the help key will bring up relevant information on functions and operation steps. If an error has occurred, the reason for it is also displayed to ease operation. ■ Large screen X-Y display mode *In memory recorder function X-Y waveforms can be displayed with the memory recorder functions. In particular, the memory recorder function has been enhanced to provide enlarged display in a larger screen area than with display by the recorder function. This provides greater utility than with previous X-Y recorders. Note: Large screen display is supported from version 2.30 of the MEMORY HiCORDER s 8841 and 8842. X-Y waveforms have been made easier to view by utilizing the entire screen display area.
