e Programmable Multi-Function Calibrator ® 0- 1kV AC/DC Voltage @ 10 - 10MQ Resistance Mowe peaa: 2 ® Autocal facility as Cee @ |EEE-488 interface — @ 2 Year warranty | Introduction The 9821 isa multi-function calibrator, with AC/DC voltage & current Safe High Voltage Operation ranges and resistance and is suitable for calibration of digital and Emphasis has been placed on safety features. Output voltages greater analogue multi-meters. than 40 volts can only be selected after pressing a safety interlock key. On selection of an output greater than 40V, there is a programmed 3 IEEE Interface supplied as Standard second delay, an audio warning bleep and a continuous flashing The IEEE-488 interface allows automatic computer control needed —_ waming light on the front panel for low cost calibration of a large number of multi-meters.The simple high level programming language gives full control of the 9821, _ Easy Recalibration enabling repetitive calibration work to be greatly speeded up. The 9821 can be recalibrated from the front panel or over the [EEE bus, ensuring fast and accurate recalibration in less than 20 minutes. Offset and Deviation Calibration constants are held in non-volatile memory. the removal of Offset store allows input of zero offset values. Digital deviation allows calibration trimmers giving improved reliability and repeatability. A the output to be changed by up to 10%. The deviation can then be read —_ simple ‘cal key’ provides calibration security directly from the display showing the percentage error in the reading of the meter under test. 19999 Full Scales with 5% Over-Range For accurate calibration of DMM’s, the ranges on the 9821 have been Self-Test and Error Detection designed to match the full scales of most digital meters. The 9821 software constantly monitors the output and displays error messages on detection of a fault or overload condition. A self-test 10 Amps. program can also be run to check that key internal functions are — The built-in 10 amp range of the 9821 allows full calibration of the operating correctly and help with fault diagnosis. large numbers of meters with 10 amp full scales. without time con: suming, bulky add-on amplifiers Six Wave Forms from 15 Hz to 20 kHz in 5 Hz Steps Sine, square. trapezoidal, triangular. ramp up and down waveforms Portable are provided. This extends the capability of the 9821 to checking the The 9821 weighs only 15 kg, and is supplied fined in a standard 3L “RMS performance of multi-meters, linearity of chart recorders, and Eurocase, remarkably portable for a full function calibrator ! amplitude checks on oscilloscopes. Additionally, a slow sweep func- tion enables the movement of needles of an analogue meter to be checked for stiction. (4) Time Electronics Limited, Botany Industrial Estate, Tonbridge, Kent.
