382260 V1.0 6/07 4
Stand Alone Operation
1. Set the Master/Slave switch located on the back of the unit to the Master position.
2. Without any load attached, use the POWER button to switch on the power supply and
the LED indicator will light. There should not be any reading on the voltmeter and
ammeter.
3. Press the Output On/Off button and its green LED will light up, the voltmeter will
display the previously set output voltage. Use the voltage control knob to adjust the
voltage to the desired level.
4. Use the Output On/Off button to turn off the output. Note: The output will automatically
shut off when one of the other voltage/current range selection buttons is pushed. This
is to prevent damage to a connected load if the voltage/current values are set too high.
5. Press and Hold the Preview button to display the previously set voltage and current
limiting values. With this button held down, you can set the current limiting value
without connecting to a load or shorting the output terminals. Note: The Output button
must be in the Off position.
Setting the Upper Voltage Limit (UVL) Value
The Upper Voltage Limit Value is an added protection for voltage sensitive loads. When
the output voltage exceeds the set UVL, the output terminal will automatically shut off and
the ALM LED will light. Note: Only one UVL value can be set for all three ranges.
1. Press the UVL/Voltage and insert a small screwdriver into the UVL adjustment
screw.
2. Turn clockwise to increase the voltage limit and counter-clockwise to decrease the
UVL value.
Remote Sensing Operation
When the output current is high or the load connection is long, there is a voltage drop
across the connecting cable. This results in a difference between the voltage at the output
terminal and load point. By making an extra connection using the Remote Sensing
Terminal to the load point, the reading at the output terminal and load point is the same.
Caution: Observe correct polarity and never short the Remote Sensing terminal
1. Connect the load to the power supply.
2. Connect the load to the Remote Sensing Terminal.
Note: Always disconnect the Remote Sensing terminal connections first.
