8. Press the M Key. The display changes as shown on the left.
Set the STV to 400 mV.
Allow the count value on the No. 2 display to fully stabilize, then press the
D Key to temporarily register the calibration settings.
If this count value is outside of the specified range, the No. 2 display will
flash and the count value will not be temporarily registered.
9. When the M Key is pressed, the status changes as shown to the left.
10. Change the wiring as follows:
Open in non-connected state
STV
DMM
Short-circuit
Zero
controller
OUTPUT INPUT
Disconnect the STV to enable the thermocouple of the cold junction com-
pensator. When doing this, be sure to disconnect the wiring on the STV
side.
11. Allow the count value on the No. 2 display to fully stabilize, then press the
D Key to temporarily register the calibration settings.
12. When the M Key is pressed, the status changes as shown to the left.
The data to be temporarily registered is not displayed if it is not complete.
Press the U Key. The No. 2 display changes to yes. Release the key and
wait two seconds or press the M Key. This stores the temporarily regis-
tered calibration data to EEPROM. To cancel the saving of temporarily
registered calibration data to EEPROM, press the M Key (while no is dis-
played in the No. 2 display) without pressing the U Key.
13. The calibration mode is ended by turning the power OFF.
