4-14 PRODIGIT
Purpose
：
To set synchronous function ON/OFF for 3250A series electronic load module.
Command syntax
：
SYNC{SP}{0|1|OFF|ON}{
；
|NL}
Description:
1.External synchronous signal (SYNC ON)
：
Using external synchronous signal
as the synchronous triggering signal of the electronic load thus controlling the
load current to be synchronous with the voltage.
2.Internal synchronous signal (SYNC OFF)
：
Using the signal at the terminal of
the input connector thus generating synchronous signal through the internal
zero-crossing circuit and isolated circuit.
For Example
：
a.SYNC ON, to set external synchronization.
b.SYNC OFF, to set internal synchronization.
WATT Meter ON/OFF
Purpose
：
To set display of power meter of 3250A series electronic load module.
Command syntax
：
WATT{SP}{0|1|OFF|ON}{
；
|NL}
Description
：
This command is to set the display of power meter. This command has to be used
in conjunction with PRES
：
OFF. When setting to ON, the monitor on the top will
change from voltmeter to Watt meter while the monitor at the bottom will change
from ammeter to Volt-Amp meter (VA) and the unit is
〝
W
〞
and
〝
VA
〞
respectively.
When setting to OFF, the Watt meter on the top will change back to voltmeter while
the VA meter at the bottom will change back to ammeter and the unit is
〝
Vrms
〞
and
〝
Arms
〞
respectively.
For Example
：
a.PRES OFF
b.WATT ON, to display WATT, VA meter.
c.WATT OFF, to display Voltage, Current meter.
WAVEFORM BANK
Purpose
：
To set waveform bank for 3250A series electronic load module.
Command syntax
：
BANK{SP}{d}{
；
|NL} d
：
0
～
10
Description
：
This command is to set the waveform bank desired to be selected.
1.waveform bank 0
～
2 are sine wave.
2.waveform bank 3
～
8 Set P.F.
3.waveform bank 3
～
8 are square wave.
