SECTION 4 OPERATION

4.3.2 VOLTAGE ENTRY
To achieve MANUAL MODE and change voltage, from any meter display light the Va, Vb, Vc LEDs by
pressing those keys.
Pressing an ARROW key (︿ or ﹀) causes selected voltages to slew up or down. Entering a number
then pressing EXECUTE causes selected voltages to change to the new value. The upper right corner
of the display shows the most recently entered voltage.
For example: To change to 125 volts, light Va, Vb and Vc LEDs as desired by pressing their keys. Type
125 and press EXECUTE. The Power Source should now be generating 125 volts.
V/I METER: ENTRY: 125.0
FREQ=60.00 Va=125.0 Vb=125.0 Vc=125.0
SENSE=INT Vab=216.5 Vbc=216.5 Vca=216.5
MANUAL MODE Ia=00.0 Ib=00.0 Ic=00.0
4.3.3 FREQUENCY CONTROL
To achieve MANUAL MODE and change frequency, from any meter display light the F LED by pressing
that key.
Pressing an ARROW key (︿ or ﹀) causes the frequency to slew up or down. Entering a number then
pressing EXECUTE causes the frequency to change to the new value. The upper right corner of the
display shows the most recently entered frequency.
For example to change to 60.50 Hz. light the F LED: enter 60.50 and press EXECUTE. The Power
Source should now be generating 60.50 Hz.
V/I METER: ENTRY: 60.50
FREQ=60.50 Va=120.0 Vb=120.0 Vc=120.0
SENSE=INT Vab=208.0 Vbc=208.0 Vca=208.0
MANUAL MODE Ia=00.0 Ib=00.0 Ic=00.0
4.4 PROGRAM OPERATE MODE
This section describes Program Operate Mode. Program Operate Mode allows pre-stored program
execution including transients.
Not all of the Program Operate features are available with the UPC-3M and UPC-1M manual versions of
the controller. Manual controllers allow editing of VOLTAGE, FREQUENCY, FORM and COUPLING
only.
When the V/I METER display is active, the lower left corner of the display will indicate the PROGRAM #
currently being executed.
