Operation Steps:
1. In initial interface, select [Mode], [More], [More], and then press [OVP] to enter the
setting interface.
2. Move the cursor to the needed setting position by pulse knob, and press the Enter
button
to change the parameter (the parameter changes from yellow to white) by
keyboard or pulse knob. Press the Enter button
again to confirm. At this time, the
set value changes from white to yellow.
3. Other parameters can be modified in a similar way.
4. Press the ON button, the electronic load starts to load, and the indicator light below the
button lights up. If you need to stop the load, press the ON button again, and the
running indicator light goes out.
4.2.9 Short-Circuit Mode
The electronic load can simulate a short circuit at the input terminal to test whether the
protection function of the measured object can operate normally when the output terminal
of is short-circuited.

When the set short-circuit time is reached (refer to Chapter 5.2 for the short-circuit time
setting), the electronic load returns to the original working state.
The actual current value consumed by the electronic load in the short-circuit mode depends
on the current load working mode and current range. During the short circuit test, the
electronic load is loaded with the full range. When one of the current/power reaches the
upper limit first, the load is loaded according to the full range of this upper limit.
Note: The short-circuit mode is effective only in CC, CV, CR and CP mode.
