2750L-3P. The resolution is 0.01 KW per phase for all other P power systems.
3.6.4
TO MEASURE THE OUTPUT POWER FACTOR (PWF=24)
This screen displays the power factor from 0 to 1.000 with 0.001 resolution. The PWF screen will read unity for loads
less than 10 digits of apparent power on the Apparent Power (APW) screen. When this screen is displayed after
another screen, it takes approximately one second to update the screen.
3.6.5
TO MEASURE THE OUTPUT APPARENT POWER (APW=25)
This screen is accessed by its screen number, 25. It displays VOLT-AMPERES with a resolution of 1 VA for 4500L-3P
and 2750L-3P. The resolution is 0.01 KVA per phase for all other P power systems.
3.6.6
TO MEASURE THE OUTPUT FREQUENCY (FQM=26)
This screen is accessed by its screen number, 26. It displays the measured output frequency with a resolution of 0.01
Hz, 0.1 Hz or 1 Hz up to 99.99 Hz, 999.9 or 5000 Hz, respectively.
3.6.7
TO MEASURE THE OUTPUT PHASE ANGLE (PZM=27)
This screen is accessed by its screen number, 27. It displays phase A relative to an external synchronizing input and
phase B and C relative to phase A. The resolution is 0.1 degree.
3.6.8
ELAPSED TIME (ELT =11)
This screen displays the total run time accumulated on the AC Power System up to 99,999 hours.
H = Hours
M = Minutes
S = Seconds

REMOTE PROGRAMMING WITH ABBREVIATED PLAIN ENGLISH (APE)
Remote programming through the IEEE-488 Interface (GPIB) consists of sending the unit address and the proper
ASCII alphanumeric characters to identify the parameter and the numerical value or other argument. The description of
the abbreviations for GPIB messages used in this section are listed in Table 3-10. These abbreviations must not be
confused with the device dependent abbreviations used to describe the AC Power System operating parameters (ex.
FRQ=Frequency, etc.).
3.7.1 UNIT
ADDRESS
This is the A value (LSN) set in the CFG screen. The Unit Address 0 through 30 corresponds to the HEX value 20
through 3E. Refer to Table 3-11 for the equivalent HEX, Binary, ASCII and Decimal equivalents. The Unit Address is
set at the factory to 1 but may be changed by selecting the CFG Configuration screen and setting a new value.
To select the CFG screen repeatedly depress the MNU key until menu screen #1 is displayed as illustrated below:
SNC = 01
CLK = 02
WVF = 03
RNG = 04
Enter the key sequence: 959 ENT
Repeatedly depress the MNU key until the menu screen #5 is displayed as illustrated below:
CFG = 16
ALM = 17
FLM = 18
CLM = 19
