• Calibration

General

The XFA/R is factory calibrated. Once calibrated it will operate with any

input format.

Allow the instrument 15 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 or voltage source

• An accurate digital multimeter (accurate to 0.05 mV and ±0.1 μA)
