Output 4-20mA Calibration
＜Loop test＞
＜D/A trim＞
Analog output is confirmed and calibrated. Establish the
environment in which analog output is confirmed.
Confirm analog output value by output of simulated current.
4mADC, 20mADC, or Other can be selected. Output can be
confirmed within 4 to 20mADC in (Other).

No.
Select simulated current to confirm. "WARN-Loop should be
1
removed from automatic control" is displayed. Press "OK".
"Fld dev output is fixed at ○mA"is displayed. Confirm
analog output value. Press OK if simulated current is not
2
different to complete. If difference is found, make
adjustment with <D/A trim>.
"NOTE-Loop may be returned to automatic control" is
3
displayed. Press "End".
Analog output can be calibrated. This is used for adjustment when
difference is found in simulated current and analog output display
during loop test.

No.
"Connect reference meter Setting fld dev output to 4mA"is
1 displayed. Confirm the ammeter display. Input displayed
current value.
Press "Yes" when ammeter display shows 4mADC. If not,
press "No". Repeat operation in item 1 above until the
2
display shows 4mADC.
20mADC is put out. Check the ammeter to input displayed
3
current value.
Repeat operation in item 3 until the ammeter displays
4
20mADC.
"Returning Fld dev to original output" is displayed. Press
5
"End".
