3.7.22
TO PROGRAM THE DEFAULT CURRENT LIMIT (INI C)
The default current limit is the value after power-up or IEEE-488 Device Clear.
The following example will program the default current limit to 10 amps.
INI
C
10
3.7.23
TO PROGRAM THE DEFAULT VOLTAGE RANGE (ALM A)
The default voltage range is the voltage range after power-up or IEEE-488 Device Clear. A value of 0 designates the
low-range. A value of 8 designates the high range.
The following example will program the default voltage range to the high range.
ALM
A
8
3.7.24
TO PROGRAM 1 OR 3 PHASE MODE (MOD)
The MOD header with the required PHS extension is used to identify the mode command. The argument is either a 1
or a 3 to specify the 1-phase or 3-phase mode respectively. A mode change by the AC Power System will cause the
output voltage to go to the default values.
The following string will set the AC Power Systems to the 3-phase mode:
MOD PHS 3
3.7.25
TO TALK (TLK) MEASURED AND PROGRAMMED DATA
The TLK header will setup the AC Power System to talk data. The TLK header will setup the AC Power System to
report a programmed output parameter if the program header is the argument for the TLK header.
To setup the AC Power System to report a measured value, attach a measurement header as the TLK argument. The
measurement headers are VLT, CUR, PWR, APW and PWF with an A, B or C extension and FQM with no extension.
The following string will setup the AC Power System to measure the phase A power output when it is talk addressed:
TLK PWR A
All arguments for the TLK header are shown in Table 3-13. Table 3-14 shows an example response for all TLK
arguments with no A, B or C extension. For 1-phase systems, all responses will only include the phase A value. For
3-phase systems, if the TLK argument includes the A, B or C extension, the response message will be only for the
indicated phase.
A GPIB Service Request (SRQ) will be generated at the completion of a measurement if the SRQ2 header is included
with the TLK string. The following string will cause the Service Request to be generated when the power system has
finished the power factor measurement.

PWF
SRQ2
