Calibrating the Module 7-3

9. Remove the 90.000 mV calibration voltage.

10. With your programming terminal, enter calibration code 1008

Hex into output word 14.

11. Observe bits 0–3 in status word 5.

After the module burns the calibration values into its

EEPROM, it returns status–OK bits set, one bit for each
channel (F Hex for all four channels). If the module could not
complete the calibration of one or more channels, it returns a
zeroed status bit for that channel (non–F Hex returned)

12. To end the calibration procedure, enter calibration code 0000

Hex into output word 14. During thermocouple/mV operation,
word 14 must be zero (which is normal operation).
