Operation Elgar CW-P Series
3-2 Operation Manual
Numeric Display. The large, four-digit display in the VOLTAGE/POWER
section is a digital voltmeter that measures and displays the power supply’s
voltage/power parameters. If the CW is operating with output power turned off,
this meter displays the voltage that the output will assume when it is turned on.
VOLTAGE MODE Lamp. This LED, 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.
V RANGE Button. This button allows you to select the 0V–135V range or the
0V–270V range of output voltage. The High or Low LED indicates the currently
selected voltage range. The output current available on the low voltage range is
twice that available on the high voltage range.
LEDs. The indicator lights on the right side of the VOLTAGE/POWER section
(VOLTS, WATTS, VA, PF, OVP) identify the currently displayed measurement
during the Program and Measure functions.
MEASURE Button. Use this button to specify what measurement is
displayed. As you press the button repeatedly to cycle through the parameters,
the associated LED illuminates to indicate the measurement shown in the four-
digit display. The MEASURE lamp is illuminated when using the Measure
function.
PROGRAM Button. Press this button to change the output voltage or OVP
setpoint. The PROGRAM lamp is illuminated when using the Program function.
Rotary Knob. This large, multi-turn knob allows you to easily select the
desired power supply voltage/power parameters.
 MENU/STATUS Section
These controls and indicators, located in the center of the front panel, are used
to make changes to non-displayed system parameters.
ENTER/SAVE Button. Press this button to enter the Menu system in order to
display and/or make changes to the system parameter settings. After specifying
the new setting, press this button again to accept and apply the change to the
currently selected parameter.
To modify more than one item in the menu system, press ENTER/SAVE after
each parameter modification once to save the change, and once more to re-
enter the menu system.
