NUMERIC DISPLAY. This large, four-digit display, located in the voltage

cluster, is a digital voltmeter that measures and displays the power supply’s

output voltage. If the power supply is operating, but the output power is turned

off, then this meter displays the voltage that the output will assume when it is

turned on.

VOLTAGE MODE LAMP. This lamp, located directly over the numeric

display, indicates that the power supply is operating in the constant output

voltage mode. This is the most common operation mode used. If the output

current rises above the level set by the current program level, this lamp turns off

and the CURRENT MODE lamp turns on.

VOLTAGE Knob. This large, multi-turn knob, at the right side of the voltage

cluster of controls, allows you to easily select the desired power supply output

voltage.

SET OVP. This is a screwdriver accessible, multi-turn adjustment located

directly under the display. To define a maximum output voltage, first turn the

adjusting screw fully clockwise. Set the output voltage to the desired trip point.

Then, slowly, turn the adjustment counter-clockwise until a fault is generated,

turning the output off.

CURRENT/FREQUENCY CLUSTER

These six controls and indicators, located in the center of the front panel, are

used to select and display the CURRENT and FREQUENCY.

MEAS/PROG Switch. This switch selects which current measurement is

sent to the meter. If the meter has been set to display current, and this switch

is set to MEAS, then the measured output current is displayed. If this switch is

set to PROG, then the selected current limit point is displayed.

CURR/FREQ Switch. This switch selects the type of quantity to be

displayed. Selecting

CURR displays the selected current, either MEAS or

PROG. Selecting FREQ displays the operating frequency.

Numeric Display. The large, four-digit display in the current/frequency

cluster shows the measured quantities described above.

CURRENT MODE Lamp. This lamp, located directly over the numeric

display, indicates when the output current has reached its selected limiting

value, i.e., the power supply is operating in the constant current mode.

CURRENT Knob. A large,

multi-turn knob allows you to set the point of

inception of the constant current mode.

FREQUENCY Knob. A large, multi-turn knob allows you to set the operating

frequency.
