• Calibration
General
The CND/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 and allow a few seconds for
signals to stabilise before accepting their value.
Equipmentrequirements
• Suitable precision 0 Ω, 200 Ω, 1 kΩ,  kΩ resistors (±0.0 % or
better accuracy)
• An Rtd simulator with ±0.0 % or better accuracy
• An accurate digital multimeter (accurate to 0.0 mV and ±0.1 μA)
