c. PF adjustment, Lag. Set the Series 800 to 120V, 120VA, 1 Amp, 50Hz, 0.0 PF lag, Operate
and adjust R63 on the Phase Control & Sense module for a reading of 0.000, ±0.001. Refer
to paragraph 4.2.5, Power Measurements. (Check this setting at 60Hz and make best
compromise setting of R63).
Step 16 - Deviation Meter Adjustment
a. Refer to paragraph 4.2.6. Set the Series 800 to 120V, 600VA, 5 Amps, 400Hz, 1.0 PF Lag,
Deviation OFF, Operate. "Enter" the DVM reading for the Deviation OFF condition. Select
the Series 800 to the 1.0% Deviation range and set the Deviation Control to cause a 1.00%
reading on the DVM. Adjust R7 located on the Display Assembly (08-109-001) for an
indication of -.100 on the Deviation Meter of the Series 800.
Step 17 - Optional Power Factor Setting
a. If the Model 800 is equipped with an optional Power Factor setting adjust R103 on the
Reference Module for the optional PF setting.
Step 18 - Line Synchronization Adjustment
a. If necessary, follow this procedure to adjust the control modulators. Set the Series 800 to
10V, 10VA, 1 Amp, 1 PF, Standby; select the frequency equivalent to that of the line, Line
Synchronization on. The line Synchronization switch is located on Rear Panel. Observe the
waveform at TP2 on the Voltage Oscillator with an oscilloscope that is line synchronized.
Adjust R133 very slowly on the Reference until the observed waveform is synchronized.
Then adjust R133, counter clock wise slowly until the waveform just falls out of
Synchronization. Determine this setting by toggling R133 through a small angle to observe
synchronization in one position and over synchronization in the other. Mark the setting of
R133. Repeat this procedure at the clock wise setting of R133 which is the limit for
synchronization. Thereafter center R133 between the two settings.
4.3.2 Model 800AE/811AE Calibration Procedure
Set-up the equipment for testing the 800AE or 811AE as shown in Figure 8-1. The watt
converter must have an accuracy suitable for the performance of the AE Series. A Rotek Model
MSB-001A with correction factors meets the requirements. The digital voltmeter calibration must be
known to within ±1ppm and there should be provisions for filtering and averaging.
In the following procedure 50Hz is used as the frequency at which the calibration adjustments
are made. This is a convenient frequency when the power line is at 60Hz, since interference "beat" is
eliminated. If the line power frequency is 50Hz then make the adjustments using 60Hz.
Step 1 - Null Adjustments
a. Connect the voltmeter to measure the voltage between TP7 and SG on assembly 08-311-
000 as shown in Figure 8-2.
b. Turn on power to the 800AE/811AE with a setting of 120V, 0VA, 1.0PF, 50Hz and Operate.
Adjust R126 for a minimum, less than ±10µV.
c. Reset the 800AE/811AE to 160V, 0VA, 1.0PF, 50Hz, Operate and observe the voltmeter
reading. Adjust R126 again to ½ the previous reading. Thereafter adjust R126 for the lowest
compromise reading on both settings (within ±70µV).
