RECALL
Purpose
：
：
：
：
Recall the state of load level and status which is stored by GPIB STORE command.
Command syntax
：
：
：
：
RECALL{SP}{1|2|3|4|5}{NL}
Description
：
：
：
：
This command is used to recall the non-volatile memory state which is store into the
memory by GPIB store command, up to 5 states can be recalled.
For Example
：
：
：
：
RECALL 1
RECALL 4
SYNC
Purpose
：
：
：
：
To set synchronous function.
C
ommand syntax
：
：
：
：
SYNC{SP}{0|1|OFF|ON}{
；
|NL}
Description:
1. External synchronous signal (SYNC ON)
：
Using external synchronous signal as
the Asynchronous 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
Purpose
：
：
：
：
To set display of power meter.
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-Ameter (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.
