• Calibration

The PMX400/TMP is factory calibrated. Once calibrated the PMX400/

TMP will operate with any sensor type or range, and any output type

or range, without recalibration. You should not have to recalibrate the

instrument before installation.

Equipment requirements

• A suitable millivolt source (accurate to 5 μV or better)

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

• A Pt100 Rtd simulator (accurate to 0.05 ˚C)

Summary

There are four stages to calibrating the PMX400/TMP

• Calibrate the millivolt inputs

• Calibrate the CJC input

• Calibrate the RTD input

• Calibrate the analogue outputs
