PF1352 USER MANUAL REV A 12/21/15
6. The “F” in front of the multiplier indicates that frequency is the parameter now
controlled by the
UP/DOWN
keys. Use the
UP/DOWN
keys to set the frequency to
the desired value. Remember that the “step size” or resolution can be changed by
holding the
SHIFT
key and pressing the
MODE
key to select the desired multiplier
value.
7. Use the
SHIFT
and
MODE
keys along with the
UP/DOWN
keys to set the output
voltage to the desired value. Make sure the unit is set to the required output voltage
range using the front panel
RANGE
switch. Remember holding the
SHIFT
key and
pressing the
MODE
key sets the resolution multiplier.
8. After the voltage and frequency (and current limit if required) are set, the load may
be energized by pressing the
OUTPUT
switch
button. (Note that is also permissible
to energize the load gradually by setting the voltage to zero, turning on the output,
and stepping the voltage up.)
The voltage, frequency, and current limit may be set at any time during the operation
of the power supply
.
Press the
MODE
key to change which parameter is to be
adjusted.
Use
the
SHIFT
and
MODE
keys to select the step size as previously
described. Then the output parameter may be adjusted with the
UP/DOWN
keys.

POWER DISPLAY MODE
A useful feature of the PF1352 is the power display mode. In this mode, the output
power in watts and the load power factor are continuously displayed along with
frequency, voltage, and current. When in this mode the
UP/DOWN
keys are disabled
and will not change output parameters when pressed. Use the
MODE
key to set the
unit in this mode. A typical power display is illustrated in figure 3-4 below.
