PRELIMINARY OPERATIONAL CHECK
BEFORE APPLYING AC SOURCE POWER TO THE POWER SUPPLY, VERIFY THAT THE
LINE VOLTAGE TO BE SUPPLIED MATCHES THE POSITION OF THE AC INPUT SELEC-
TOR SWITCH AT THE REAR PANEL (FACTORY DEFAULT IS 115V).
A simple operational check after unpacking and before equipment installation is advisable to
ascertain whether the power supply has suffered damage resulting from shipping.
Refer to Figures 2-1 and 2-2 for location of operating controls and electrical connections. Tables
2-1 and 3-2 explain the functions of operating controls/indicators and keypad keys, respectively.
1.
With
POWER
switch set to down (OFF) position, connect the power supply to source
power.
2.
With no load connected, set
POWER
switch to the up (ON) position. Each time the unit is
turned on an internal self-test is performed and the power on indications (Figure 2-3) are
visible. If these indications do not appear, the power supply will be inoperative.
The alphanumeric display (LCD) indicates the model and GPIB address. After a few sec-
onds, the display presents the power supply default values: Local mode (
LOC
), Output On/
Off (
Off
), output voltage and current (
0.000V 0.000A
) and command entry status (see
Figure 2-3.). Overvoltage and overcurrent protection are set to the maximum values (PAR.
1.4.4), but are not displayed. To enable the output of the BHK-MG, press the OUTPUT ON/
OFF key on the front panel

3.
Allow unit to warm up for at least 15 minutes.
4.
Connect a digital voltmeter (DVM) to the output jack at the front panel.
5.
Press
VSET
key. Verify bottom line of LCD reads
Vset (=_=_=) 0.0 V
. Use number
keys to enter nominal output voltage (e.g. for BHK 500-80MG, 500V is the nominal output
voltage) and press
ENTER
. Output voltage will be displayed at bottom left of LCD. Verify
the LCD reads CV (constant voltage mode).
