1. Determine the output current and voltage requirement
of your load.
2. With the a-c POWER circuit breaker/switch set to OFF,
disconnect the load and connect a short circuit across
the OUTPUT and COMMON terminals.
3. Set the BOP MODE switch to VOLTAGE and the VOLT-
AGE CONTROL switch to ON, then set a-c POWER cir-
cuit breaker/switch to ON.
4. Current limits are recommended to be greater than the
maximum current required for the load by 10% of the
rated current of the unit (e.g., for a 6A BOP and a load
that requires 3A, set current limits to ±3.6A).
If specific ± current limits are not needed, use a screw-
driver to adjust the
+
I
CURRENT LIMIT potentiometer
to full clockwise position and
-
I
CURRENT LIMIT
potentiometer to full counterclockwise position.
If specific ±current limits are needed, proceed as fol-
lows:
a. Turn VOLTAGE CONTROL fully counterclockwise.
Use a screwdriver to adjust the
–
I
CURRENT
LIMIT potentiometer as desired (recommended to
be 10% greater than the maximum negative current
required for the load), monitoring the CURRENT
meter for the correct limiting value.
b. Turn VOLTAGE CONTROL fully clockwise. Use a
screwdriver to adjust the
+
I
CURRENT LIMIT
potentiometer as desired (recommended to be 10%
greater than the maximum positive current required
for the load) monitoring the CURRENT meter for the
correct limiting value.
c. Set the VOLTAGE CONTROL switch to OFF. Set a-c
POWER switch/circuit breaker to OFF, then remove
the short circuit from the output but leave the load
disconnected.
5. Set the BOP MODE switch to CURRENT, CURRENT
CONTROL switch to ON and set a-c POWER switch/
circuit breaker to ON.
6. Adjust the
+ V
and
– V
VOLTAGE LIMIT potentiome-
ters to the required output (compliance) values. Pro-
ceed as follows:
a. Turn CURRENT CONTROL fully counterclockwise.
Use a screwdriver to adjust the
–
V
VOLTAGE
LIMIT potentiometer as desired.
b. Turn CURRENT CONTROL fully clockwise. Use a
screwdriver to adjust the
+
V
VOLTAGE LIMIT
potentiometer as desired.
c. Set a-c POWER switch/circuit breaker to OFF, then
connect a short circuit across the OUTPUT and
COMMON terminals.
d. Set a-c POWER switch/circuit breaker to ON and
use the CURRENT CONTRol to adjust the output
current to zero.
e. Set a-c POWER switch/circuit breaker to OFF and
remove short across OUTPUT and COMMON termi-
nals.
7. Connect the load to the BOP OUTPUT and COMMON
terminals.
8. Set a-c POWER switch/circuit breaker to ON and use
the CURRENT CONTROL to adjust output current
through the load to the required value.
