6. When the M Key is pressed, the status changes as shown to the left.
Set the 6-dial to 10 Ω.
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.
7. 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 registered
calibration data to EEPROM.
To cancel the saving of temporarily registered calibration data to EE-
PROM, press the M Key (while no is displayed in the No. 2 display) without
pressing the U Key.
8. The calibration mode is quit by turning the power OFF.
For Controllers that have a transfer output (E5AN/EN-H@@F), transfer output
calibration continues to be performed. For details on the settings, refer to 6-6
Calibrating the Transfer Output on page 292.
In this example, calibration is shown for a Controller with a current input set as
the input type.
1,2,3... 1. Connect the power supply.
2. Connect an STV and DMM to the current input terminals, as shown in the
following diagram.

3. Turn the power ON.
4. Move to the calibration level.
This starts the 30-minute aging timer. This timer provides an approximate
timer for aging. After 30 minutes have elapsed, the No. 2 display changes
to 0. You can advance to the next step in this procedure even if 0 is not
displayed.
5. When the M Key is pressed, the status changes as shown to the left.
The No. 2 display at this time shows the currently entered count value in
hexadecimal. Set the STV to 20 mA.
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.
