■ V-SHAPE CHARACTERISTICS (model: MFS-V)

•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.

■ PARALLEL CHARACTERISTICS (model: MFS-P)

•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 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.

Proceed to output 2 adjustment.

4. Connect an ammeter or voltmeter to output 2 monitor terminal.

5. Apply input signal required for 100% output. (within 37.5 – 100%)

6. Turn output 2 adjustment until 100% output is monitored.

For output 1, input signal for 100% output is fixed to 100%, while for output 2, input signal for 0% output is fixed to 0%.
