Output Calibration - Omron E5AR-T User Manual

Section 9 User Calibration

9.6 Output Calibration

• The procedure for calibration when linear current output is selected is provided in this section.
• Output calibration is displayed after input calibration has been finished (i.e., after the input calibration
values are registered). (Perform aging for at least 30 minutes.)

1. The registered input calibration value state is displayed as shown at left.
2. Connect a precision digital meter (DMM below) to the output terminal of the
linear current output as shown below.

3. Press the M Key. The display at left will appear and 20 mA calibration will
begin.
4. While viewing the output on the DMM, use the U and D Keys to set the
output to 20 mA. In the example at left, 20 mA is displayed at a value 2
digits smaller than before calibration.
5. Press the M Key. The display at left will appear and 4 mA calibration will
begin.
6. While viewing the output on the DMM, use the U and D Keys to set the
output to 4 mA. In the example at left, 4 mA is displayed at a value 2 digits
smaller than before calibration.
7. Press the M Key. The display at the left will appear. This display will not
appear if all of the required data has not been tentatively registered, or if
the data has not been changed.
Press the U Key. Display No. 2 will show yes. Two seconds after the Key
is released or when the M is pressed, the tentatively registered calibration
data will be stored in EEPROM. If you do not wish to save the data in
EEPROM, press the M Key instead of the U Key.
