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 Ð 12 with a multimeter.

4)Input: Check that the input signal is within 0 Ð 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 LEDsÕ colors and flashing patterns help you to easily identify the transmitterÕs status and confirm the setup actions in each step of Calibration Modes. Please read the following explanations referring to ÒCalibration Flow ChartÓ 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.

*1. Fine zero and calibrations are performed for 0% and 100% output regardless of the input value.
