If the unit is in commanded Voltage mode, the DC OFF key electrically disconnects the output
from the load; if the unit is in commanded Current mode, the DC OFF key short circuits the out-
put. The DC ON key restores the previous status if these settings were not changed by the key-
pad and/or VOLTAGE/CURRENT controls.
1. With the output disabled, the display reads:
2. To enable the output, press DC ON; the display briefly changes to:
then the display reads:
If the value of the load is less than the programmed voltage divided by the programmed current
(R

), the MBT power supply will be forced into Current mode and the VOLTAGE
MODE indicator will go off and the CURRENT MODE indicator will go on.
Pressing the DC OFF key causes the relays to disconnect the load from the power supply out-
put; the display shows the programmed values for voltage and current.
