F Calibration: thermocouple 1
(1) When [ ] is displayed, the 30-minute timer is displayed on the
No.2 display and counts down. This timer serves as a guide for the
aging time when aging is required.
(2) First, calibrate the main input. Press the
(50mV calibration display). Set STV output to 50mV . When the
value on the No.2 display has stabilized (changes of several digits
max.), press the
(3) Press the key to display [
STV output to 0mV . When the value on the No.2 display has stabi-
lized (changes of several digits max.), press the
rarily save the calibration data.
(4) Next, calibrate the cold junction compensator. Press the
display [ ] (310mV calibration display). Set STV output to
310mV . When the value on the No.2 display has stabilized (changes
of several digits max.), press the
calibration data.
(5) Press the key to display [
STV output to 0mV . When the value on the No.2 display has stabi-
lized (changes of several digits max.), press the
rarily save the calibration data.
(6) Finally, calibrate the bias compensation value. Disconnect the STV ,
and enable the thermocouple of the cold junction compensator.
When carrying this out, make sure that the wiring on the STV is
disconnected.
Make sure that the cold junction compensator is set to 0_C and
press the key. The display changes to [
play for the bias compensation value). When the value on the No.2
display has stabilized (changes of several digits max.), press the
key to temporarily save the calibration data.
(7) Press the key until the display changes to the data save dis-
play. Press the
two seconds later the calibration data is saved to internal memory.
If you press the
calibration data is invalidated.
(8) This completes calibration of the thermocouple 1 group. Press the
key to return the display to [
