Set the voltage limit as follows:
1. Press the SELECT button until the VOLTAGE LIMIT LED is lit. The present value of the voltage
limit is shown on the center display.
2. Change the limit value using either the numeric or cursor buttons.
3. Press ENTER to update the actual limit value.
If an Err2 message appears (illegal parameter entered), check to see that the output voltage is less
than or equal to the new desired voltage limit.
Set current limit
The power supply output current is clamped at the current limit. If the current limit is reached, the
output voltage may not equal its programmed value. When the unit is current limited, the STATUS
LIMIT LED is on.
Set the current limit as follows:
1. Press the SELECT button until the mA LIMIT LED is on. The present value of the current limit is
shown on the center display.
2. Change the limit value using either the numeric or cursor buttons.
3. Press ENTER to update the actual limit value.
Set current trip
The current trip shuts off the high voltage when the output current exceeds the trip value. The current
trip value is set in the same manner as the voltage and current limits. After a current trip occurs, the
ITRP (current trip) message will appear on the middle display. Current trips are cleared in the same
fashion as voltage trips.
Set the current trip as follows:
1. Press the SELECT button until the mA TRIP LED is on. The present value of the current trip is
displayed in the center window.
2. Change the limit value using either the numeric or cursor buttons.
3. Press ENTER to update the actual trip value.
