Operations 44
CC/CV/CR/CW/CZ
Indicates the module’s operating mode.
VFD Display Screen
Shows four lines of numbers. The first line shows the measured voltage value. The second line shows the measured
current value. The third line shows the measured circuit’s power value. The fourth line shows the setup value, and users
can set A/V/Ω value here.
Short
Is displayed when short circuit function is enabled on the module.
Tran
Is displayed when TRANSIENT mode is enabled on the module.
List
Is displayed when selecting LIST mode in the Configuration menu.
Sense
Is enabled in remote sense function. There is no need to set this in the menu, as you only need to link the circuit to
remote sense terminals and ‘Sense’ will be displayed.
4.6 Transient Operation
Transient operation enables the module to periodically switch between two load levels, as might be required for testing
power supplies. Transient operation can be turned on and off from the front panel (Tran and Trig keys). The parameters
of the transient operation include: A level, A width, B level, B width, and transient testing modes.
There are three different transient testing modes: continuous, pulse, and toggle.
Mode Description
Continuous Generates a respective pulse stream that toggles between two load levels.
Pulse Generates a load change that returns to its original state after some time period.
Toggle
Generates a repetitive pulse stream that toggles between two load levels. It is similar to con-
tinuous mode except that the transient points are controlled by explicit triggers instead of an
internal transient generator.

4.6.1 Continuous
The electronic load generates a repetitive pulse stream that toggles between two load levels. The load switches the state
between two value settings, value A and value B.
