•Input Range Adjustment

1. For current output, connect an ammeter to output 1 monitor terminals.

Current signal is measured at both ends of a diode inserted in series to the output 1 driver.

Input resistance of the ammeter must be 10Ω at the maximum to ensure accurate measurement.

For voltage output, connect a voltmeter across the common and output 1 monitor (+) terminals.

2. Apply an input signal desired for 0% output. (within 0 – 62.5%)

3. Turn output 1 adjustment until 0% output is monitored.

4. Adjust output 2 the same way as output 1. Allowable input range for 0% output is 37.5 – 100%.

Input signals for 100% output are fixed to 100% for output 1, 0% for output 2.
