• 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.

quipment requirements

• 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)
