Select the MOD screen:
3 0
ENT
Program the 3-phase mode:
3
PRG ENT
The last mode programmed for the power system will be the default Mode at power-up.
3.5.18
TO PROGRAM THE DROP PERIODS (DRP=28)
Select the phase (PHZ) screen by entering the keystrokes:
7
ENT
The display will show the PHZ parameter screen
PHZ MON A = 0.0 B = 240.0 C = 120.0
To drop the output waveform starting at 90 degrees, enter the keystrokes 90 A PRG.
Select the Drop screen (DRP=28) by entering the keystrokes 2 8 ENT.
The display will show the DRP parameter screen.
DRP MON A = 0 B = 0 C = 0
To drop the output waveform for phase A for 3 cycles enter the keystrokes"
3
A
PRG
ENT
Verify that phase A drops at the 90 degrees point of the sine wave for 3 periods of the programmed frequency.

TO MEASURE THE OUTPUT
Seven measurement screens display the output voltage, current, power, apparent power, power factor, phase and
frequency. The phase A, B and C output values are shown simultaneously for 3-phase systems.
While viewing any measurement screen, except ELT, any other measurement screen may be displayed by repeatedly
depressing either the MON or PRG key. The screen may also be displayed by entering its equivalent screen number
followed by depressing the ENT key. Refer to Table 3-6 for all measurement screen numbers.
3.6.1
TO MEASURE THE OUTPUT VOLTAGE (VLT=21)
The voltage screen displays the actual TRMS output voltage with 0.1 volt resolution. This voltage is the voltage at the
External Sense connector of the AC Power System. To access the voltage screen, depress the keys:
21
ENT
3.6.2
TO MEASURE THE OUTPUT CURRENT (CUR=22)
The current screen displays the actual TRMS load current. The resolution is 0.01 amp for the 4500L-3P and 2750L-3P.
The resolution is 0.1 amp per phase for all other P power systems.
3.6.3
TO MEASURE THE OUTPUT POWER (PWR=23)
The power screen displays the actual true power delivered to the load. The resolution is 1 watt for the 4500L-3P and
