•Calibration
General
The UCV/AR is factory calibrated. Once calibrated it will operate with
any input or output format without recalibration.
Allow the instrument 1 minutes of powered operation (to reach a
stable temperature) before calibration.
During calibration allow a few seconds for signals to stabilise before
accepting the value.
Equipment requirements
• A suitable current/voltage source (must be able to generate , 10,
20, 0 mA and , 10, 20, 0 V to ±0.0 % or better accuracy)
• An accurate digital multimeter (accurate to 0.0 mV and ±0.1 μA)
