1044 Voltage and Current Calibrator
Calibration, Test & Measurement V1b 27/03/09 Source and Measure Current and Voltage 3 Voltage Ranges: 0 – 20V 3 Current Ranges: 0 – 20mA 0.05% Accuracy Portable with carry case The 1044 is an accurate, low cost portable calibrator designed for use in a wide range of applications. High performance and ease of use make it suitable for test engineers, R&D, service, and calibration technicians. Offering both versatility and practicality the 1044 can source and measure voltage and current. The 0.05% accuracy is ideal for simulation and calibration in most engineering applications. The 1044 combines the advantages of digital accuracy with analog controls. Progressing from the familiar functions of the Time Electronics 1030 calibrator, the 1044 offers more ranges, better accuracy and the ability to measure as well as source. The large, easy to read LCD display shows the actual output, even when the connected load exceeds the specifications. This important feature eliminates the risk of large errors when connecting to unknown loads. The display also shows if the battery becomes low. In the source mode, voltage up to 20V and current up to 20mA may be generated in three ranges. When in current source mode the 1044 has a high 24V compliance voltage which is ideal for powering process control loops. In the measurement mode, the range and function can be easily selected with the measured input accurately shown on the LCD display, operating in a similar way to a multimeter. The 1044 is housed in a pocket sized, ABS case and comes with a leatherette carry case containing a compartment for storing test leads. Connections are by standard 4mm plugs or by simply clamping the wires under the terminals. A single 9V battery powers the unit or an external 12V DC power supply may be used which disconnects the internal battery.

1044 Applications
In the source mode, the 1044 may be used to calibrate meters, thermocouple indicators, data loggers, for signal injection, semiconductor characterisation or as a backing off source. In the measure mode, the 1044 may be used in the same way as a multimeter.
