Programable DC Electronic Load User Manual

6.2.2 Delay On

If users set the delay before the electronic load is loaded each time, no matter what mode
it is running, when the ON button is pressed, the electronic load will wait for the set delay
time and then start loading.
6.2.3 V Trigger
V Trigger is the voltage value of automatically-started loading after setting the list mode.
After setting the self-start voltage, enter the list mode without pressing the ON key to
enable the load. When the input voltage of the electronic load exceeds the set self-start
voltage, the list mode will automatically start.
This operation is suitable for testing environments that do not need manual operations
such as automated production lines. The default self-start voltage of the device is 0, which
means it is not enabled. When users need to use, first set the required V Trigger in the
parameter setting, then users only need to set the parameters in the list mode according
to the normal operation, and then enter the test. When the electronic load detects that the
external input voltage exceeds the set value, it will run automatically and check out the
result.

6.2.4 OVP

Overvoltage protection is used to protect the equipment from damage as much as
possible under overvoltage conditions. After being turned on, when the external input
voltage exceeds the voltage range that the electronic load can withstand, the load will
short-circuit the external power supply to protect the load itself from damage. This function
is mainly suitable for LED power supply testing and other fields.

6.2.5 Digit Filt

Adjusting the parameter of digital filter can improve the stability of the displayed value.
The electronic load has a total of 4 digital filter parameters that can be selected. The
larger the filter parameter, the better the effect and the more stable the displayed value.
The load defaults to LV4 digital filter and users can set it according to actual needs.

6.2.6 Ripple

There are three options for ripple measurement: voltage high speed, medium speed, and
65
