• Then the status display reads
SET
(setpoint mode), the
DC VOLTS
display reads
0000
Volts, the
DC AMPERES
display reads minimum Amperes (see Note 1, below).
NOTES: 1. A minimum programmed current (actual value depends on model) is required to
ensure proper operation of the power supply under all load conditions. Pro-
grammed current is automatically set to be at least the minimum current.
2. If an error indication is blinking in the Status display, refer to Table 3-1 for an expla-
nation of error codes.
3.
Rotate
VOLTAGE
adjust knob clockwise. Verify that
DC VOLTS
display increases in large
(X 100) increments.
4.
Press and rotate
VOLTAGE
adjust knob clockwise. Verify the
DC VOLTS
display increases
in finer increments than step 3.
5.
Adjust
VOLTAGE
adjust knob clockwise until Status display reads
>MAX
. Tap either
VOLT-
AGE
or
CURRENT
adjust knob once to enter values. Verify Status display is blank
6.
Connect a digital voltmeter (DVM) to the (M+) and (M–) terminals on the rear panel.
7.
Press and release
DC OUTPUT
switch to enable the output. Verify
DC OUTPUT
indicator
lights.
8.
Compare the programmed output voltage value (step 5) with the voltage reading of the
DVM; the difference between the two should not exceed 0.05% of the maximum voltage of
the unit.
9.
Compare the voltage reading of the
DC VOLTS
display with that of the DVM; the difference
between the two should not exceed 0.1% of the maximum voltage of the unit.
10. Enter different value for output voltage, then repeat steps 8 and 9 using different values for
programmed voltage.
11. Disable the output by pressing and releasing
DC OUTPUT
switch; verify front panel
DC
VOLTS
and
DC AMPERES
displays read 0.0V and minimal current and the DC OUTPUT
indicator is off.

INSTALLATION
2.6.1
RACK MOUNTING
The unit is intended to be mounted directly in a 19-inch wide rack. Optional slides (see Table 1-
4) can be used.

WIRING INSTRUCTIONS
Interconnections between an a-c power source and the power supply, and between the power
supply and its load are as critical as the interface between other types of electronic equipment.
If optimum performance is expected, certain rules for the interconnection of source, power sup-
ply and load must be observed by the user. These rules are described in detail in the following
paragraphs.
