Power Factor / Phase Operating Procedure
CAUTION: Prior to making any connections, place the PMC in Standby Mode. The
following procedure employs initial output values of 120 volts and 5 amps at 60 Hz and
0°, 30° and 60° phase values. A full meter calibration would include other values.
The Phase Convention in the PMC is determined by the following equations:
Voltage: V(t) = Vo sinωt
Current: (t) = Vo sin (ωt + Θ)
Power: Vrms Irms cos Θ
VARS: Vrms Irms sin ( -Θ)
Power Factor: Cos Θ
Where: Θ= phase angle in degrees between voltage and current.
Phase Angle Sign of Power Sign of VARS Power Factor
0 < Θ≤90 + - Lead +
90 < Θ≤180 - - Lead -
-180 < Θ≤-90 - + Lag -
-90 < Θ≤0 + + Lag +
Turn-OFF the PMC and connect to the Model 931A System Analyzer as shown below and

Voltage or Current settings entered are outside of the
present operating range.
19. Press STBY The STBY LED will illuminate, and OPER LED will
extinguish. No output signals will be present at the
output terminals.

14
Normal/Deviation
In the % deviation mode the PMC computes and displays the output value according to the
formula:
PMC Display Value = (METER C.P. - PMC output value) X 100 %
METER F.S.
The PMC must have both the meter full scale value (Meter F.S.) and the meter calibration
point (Meter C.P.) to perform the necessary calculation.
To enable this function, press %DEV and set the PMC output value to the meter's full scale
value (it is not necessary to press OPER) . The display will read METER F.S. = XXXXX
YY where XXXXX YY represents the meter's full scale value and units.
Press %DEV again and the display will change to METER C.P. = XXXXX YY. Enter
the meter calibration point by using the keypad or RECALLing a stored setting. Do not
use the Modify Controls.
Press the %DEV key again to display METER = 00.00%. The PMC now displays the
deviation from the selected calibration point in percent of meter full scale. The previous
displays can be reviewed and/or changed by pressing the %DEV key.
Repeatedly press the % DEV key until the METER = XX.XX% is displayed again. Press
OPER to intitiate the output. Use the rotary knob or the modify keys to change the output
level and the % deviation displayed. Do not enter a value from the keypad or use the
RECALL feature. A new full scale or calibration point must be entered using the keypad
or RECALL feature. Changing the full scale or calibration point resets the percent
deviation to zero.
Memory
The Memory feature is useful for storing frequently used output settings and quickly
recalling them later. An output setting can be entered into the memory by simply pressing
the STORE key. Illumination of the STORE LED indicates that stored values are present.
Up to 99 settings can be stored. The display will flash memory store # after each entry and
will continue to flash on and off if all of the memory locations have been filled.
Output settings in memory are recalled by pressing the RECALL key. The memory
operates on a first in, first out (FIFO) basis. This sequence will continue whereby the first
setting stored will also follow the last when recalling through all of the stored settings.
Pressing the CLEAR key clears all memory settings.
The keypad may be used to help move through the stored settings. Pressing 0 then
RECALL recalls the first stored setting. Entering a number other than zero and pressing
RECALL recalls the output setting at that location.
Calibration
External Adjustments
This section consists of test procedures that check the PMC’s output amplitude and phase.
If a discrepancy with the specified tolerances is encountered, modifications are made to the
stored calibration constants.

15
Calibration Mode
The stored calibration constants can only be modified while in the calibrate mode. The
calibrate mode is identified by a circle with a cross character appearing in the right-hand
position of the display, usually after the units designator. While in the calibrate mode any
or all of the stored constants may be modified. There are two methods of exiting the
calibrate mode. If STORED is pressed, all of the modified calibration constants will be
stored in non-volatile memory for use during regular operation. If RESET is pressed, the
modified calibration constants will be discarded and the PMC will revert to normal
operation using the previously stored constants.
PMC operation in the Calibrate Mode differs from normal operation. Only five output
amplitude levels are available for each range. These are 1/10, 1/4, 1/2, 3/4 and top of
range. Once in the desired range, the CLEAR key cycles the output through these five
values. Also, only 60 and 400 HZ frequencies and 30° phases are available.
Calibration Constants
There is one calibration constant for the bottom and one for the top of each range. When
the output is at 1/10 of range, the bottom constant may be modified. The top of range
constant may be modified only while the output is set to top of range. No adjustments can
be made at the 1/4, 1/2, or 3/4 settings.
Make modifications by entering a number on the keypad and pressing ENTER. During
amplitude alignment the output will change approximately .01% times the number entered.
For phase the factor is 0.1°. A long settling time should be allowed (10 seconds or more)
after each adjustment is made.
NOTE: the two calibration constants for each range affect each other. A +0.1%
change at the top of range will produce a 0.1% change at the bottom of range . A
+1.0% change at the bottom of range will produce a +0.1% change at the top of
range.
After aligning the top and bottom of ranges, recheck both outputs to find any interaction in
the alignments.

16
Entering Calibration Mode
To access the calibrate mode, the operator must know the Key Code for the particular
instrument. The Key Code is set to the instrument’s serial number when shipped from the
factory. Access the calibrate mode in the following manner:
1. With the PMC in the reset mode, press and hold the MODIFY UP arrow key. Press
RESET. The display will show: ENTER KEY #0000.
2. Use the numeric keypad to enter the Key Code and press ENTER.
NOTE: If an incorrect Key Code is entered the PMC will revert to Reset.
3. Once the correct Key Code is entered, the display will change to CHANGE KEY #
XXXX. The key Code may now be modified.
CAUTION: Ensure to properly record the Key Code if modified and restored.
4. Press ENTER for calibrate mode operation signified by a circle with a cross character
in the right-hand portion of the display.
Typical Calibrate Routine
1. Enter Calibrate Routine as previously described.
2. Set the PMC for operation in desired mode and range using the top of the range value.
As an example, use the following sequential steps to test the top of the 100-volt DC
range:
a. Press DC.
b. Press VOLTAGE.
c. On the numeric keypad, enter 100.
d. Press V.
e. Press OPER.
f. Allow the output to settle and perform measurement.
3. The top of range calibration constant and the output level can now be modified by
entering a number on the numeric keypad and pressing ENTER. During amplitude
alignment the calibration constant and the output level will change approximately
0.01% times the number entered. For phase corrections the factor is 0.01°. Adjustments
to calibration constants may be made at the top of range and 1/10 settings only.
4. The 1/10, 1/4, 1/2, 3/4, and top of range outputs are programmed and available by
pressing the Clear Key. The PMC will not revert to Standby when CLEAR is pressed,
but the output will change to the newly displayed value.
5. To adjust Voltage or Current during Power, setup Power using the normal sequence,
e.g., 60 Hz, POWER, VOLTAGE, 150V, CURRENT, and 1A. Then select either
VOLTAGE or CURRENT to monitor. The Clear Key will cycle the setting selected.
6. While most functions operate in their normal fashion in calibrate mode, several
characteristics are worth noting: Frequency and phase are not adjustable; only 60 / 400
Hz are available and the phase is set to 30°.
