4.6 Triggered operation

4.6.1 Trigger function

Trigger operation can be used in the following operations: transient pulse
output, triggered output and list output. The electronic load have 5 kinds of
trigger modes to Synchronously trigger the tested instrument, before enable the
trigger function, users should first select trigger source.

4.6.2 Trigger source


Keyboard (
press

External trigger signal(TTL level)：the 1st pin of the 8 pins connector on the
rear panel of the main frame is trigger input terminal, when external trigger
signal is available, input a low pulse(>10uS) to the internal, the load will
enable a trigger operation.

Bus trigger: when bus trigger is available, as soon as the load receive a
trigger command (*TRG) from the communication port, the load will enable
a trigger operation.

Timer trigger: when timer trigger is available, the main frame will enable a
trigger operation periodically.

Trigger maintenance: when trigger maintenance is available, only when the
load receive the trigger command (TRIG:IMM) from the communication
port, the load will enable a trigger operation.

4.7 Short operation

The load can simulate a short circuit at its input. During front panel operation,
you can press
affect the present setting. When turn off the short state, the load returns to the
original set state.
The actual value of the electronic in short operation depends on the mode and
range active when the short is turned on. In CC, CR mode, the maximum short
current is 120% of the current range. In CV mode, short means setting the
load's constant voltage to be 0V.
When in remote control mode （USB / RS232 / GPIB / Ether-net） , you can send
SCPI command INPut:SHORt ON to enable the short operation
