The 7069 is a current, voltage, and loop calibrator that meets the needs of R&D labs and process control engineers. It provides source and measure functions in three ranges, plus a transmitter simulator/sink function. Accuracy is 0.02% of span with a display resolution of 4.5 digits.

Output modes include steps and ramps. No menus to learn, just switches and buttons. A multi-turn potentiometer controls coarse output adjustment while increment and decrement buttons are provided for fine control. The source output can be reversed (+/-) and zeroed at the flick of a switch. The front panel features a large easy-to-read 4.5 Digit LCD display that auto-ranges to allow the ranges to be extended by 10% above the normal 0.2/2.0/20 full scale. Manual reset of the ramp function is also provided for quick restore.

When used as a source the output can be zeroed and reversed to enable the calibration of centre-zero type voltage or current instruments e.g. –10V to 0 to +10V.

If the unit is not operated for approximately 15 minutes, it will automatically power down. If required this feature can be disabled in the user set-up.
