•Calibration
General
The CLC/AR is factory calibrated and should not require adjustment
until the next scheduled calibration. However, if you require a different
input or output range to the one ordered, you will have to recalibrate
the instrument.
Allow the instrument 15 minutes of powered operation (to reach a
stable temperature) before you start the calibration.
During calibration allow a few seconds for signals to stabilise before
accepting the value.
Equipmentrequirements
• A suitable current/voltage source (must be able to generate mA and
voltage signals to ±0.05 % or better accuracy)
• An accurate digital multimeter (accurate to 0.05 mV and ±0.1 μA)
