Calibrating a Voltage Input

In this example, calibration is shown for a Controller with an analog input, with a voltage input set as
the input type.

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 as follows:
• Input type 27 or 28:
• Input type 29:
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.
6. When the M Key is pressed, the status changes as shown to the left.
Set the STV to 1 V.
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 non-volatile memory.
To cancel the saving of temporarily registered calibration data to non-volatile
memory, press the M Key (while no is displayed in the No. 2 display) without
pressing the U Key.
8. The calibration mode is ended by turning the power OFF.
For Controllers that have a transfer output, you can continue by calibrating the
transfer output. For detailed setting methods, refer to 7-6 Calibrating the Transfer
Output.
