CHECKING
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) DIP SW setting: Check that the switches are set to appropriate positions.
3) Power input voltage: Check voltage across the terminal 11 – 12 with a multimeter.
4) Input: Check that the input signal is within 0 – 100% of full-scale.
5) Output: Check that the load resistance meets the described specifications.
I/O RANGING & FINE ADJUSTMENTS
After the DIP SW setting is complete, set up the precise input and output range using the front control buttons.
The front LEDs' colors and flashing patterns help you to easily identify the transmitter's status and confirm the setup actions
in each step of Calibration Modes. Please read the following explanations referring to "Calibration Flow Chart" below.

When you set 0% or 100% input/output ranges,
keep pressing UP or DOWN button until the
LD1 flashes for approx. 2 seconds and turns off,
which indicates the setup is complete.
When you release the button, the LD1 is returned
to ON.
If the LED does not change, the entered level may
be inappropriate, i.e. out of usable range.
