C-16 Calibration
Calibrating an Analog Voltage (e.g., 1…5V DC) Input (900-TC8 &
900-TC16)
In this example, calibration is shown for a Controller with an Analog Voltage
Input (Input Type 2, 3, or 4).
1. Connect the power supply.
2. Connect an STV and DMM to the voltage input terminals, as shown in
the following diagram.
Figure C.31
3. Turn the power ON.
Figure C.32
4. Move to the calibration function group.
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 in the figure
below.
The No. 2 display at this time shows the currently entered count value in
hexadecimal. Set the STV as follows:
• Input Type 2 or 3: 5V
• Input Type 4: 10V
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.
