2.7 Short Circuit Operation
The electronic load can simulate a short circuit to test the protection performance of the tested
device. The short circuit operation can be enabled and disabled by setting in the main menu, or via the
remote command (INPut:SHORt ON/OFF). The other set values will not be changed when the short
circuit operation is enabled. The short-circuit value depends on the present operating mode of the load,
and the short-circuit value for each model is shown as follows:
Model 3720A 3721A 3722A 3723A 3724A
Mode
CCL 3.3A 4.4A 2.2A 3.3A 2.2A
CCH 33A 44A 22A 33A 22A
CV 0V 0V 0V 0V 0V
CRL

CPV 270W 420W 220W 370W 270W
CPC 0W 0W 0W 0W 0W
Note: in short circuit operation, the Von point and current limit level should be taken into
consideration, which may cause the shut down of the input, thus interrupt the short circuit operation.
2.8 Triggered Operation
The triggered operation is mainly used to make the load keep synchronized with other test
equipments or events. Array 372x Series electronic load provides various triggering modes, which can
be applied to the following occasions:
