⚫ Toggled: Generates a repetitive pulse stream that toggles between two
load levels. Similar to continuous mode except that the transient points are
controlled by explicit triggers instead of an internal transient generator.
4.4.1 Continuous
In CC mode, transient testing can be used to check the stability of the source
voltage. Transient function has two current levels (A level, B level), which
should be in the same range (high range or low range). You can set the A/B
level delay time and the rise/fall slew via the main frame keyboard. The slew
rate determines the rate which the level changes at. Press key, the load
will continuously switch between the A/B levels preset. Transient load are
usually used to test the power supply’s performance under load continuous
changing conditions. Figure 4-6 shows the current waveform of continuous
transient operation mode.

4.4.2 Pulsed
In pulsed mode, you can set A/B value via mainframe keyboard or remote
control. A/B rise/fall rate and delay time should be the same. The electronic
load will automatically switch to A level, after maintaining A width time, switch to
B level, it won’t switch to A level until the instrument receive the pulse signal.
The following picture shows the current waveform in pulse transient operation.

4.4.3 Toggled
In toggle mode, the electronic load will switch between A level and B level when
receiving a triggering signal after the transient operation is enabled. The
following picture shows the current waveform in toggle transient operation.
