3.1 Install Load Connection Wire

The electronic load is connected to the tested object through the "+" and "-" terminals on
the front panel. When making input connections, users need to pay attention to whether
the core diameter of the input wiring is appropriate and whether the positive and negative
polarities correspond. The wire connecting to the load must be thick enough to reduce the
voltage drop on the wire. When measuring large currents, a larger voltage drop will be
generated, so it is recommended to use the Sense terminal of the electronic load for
compensation to ensure measurement accuracy.
Note: Before the connection and test, be sure to check whether the polarity of the
input terminal is connected correctly, otherwise the instrument may be damaged.
3.2 Power on and Run
The correct power-on and self-inspection processes of the electronic load are as
follows:
1. To power the electronic load on, please connect the power cord correctly, adjust the
ON/OFF switch on the rear panel to ON, and press the power button on the front
panel. At this time, the power button is green. The electronic load screen will display
the progress bar of current power-on and self-inspection, instrument information and
other parameters.
2. After initialization, the current measuring status will be displayed on the screen. If the
start-up mode has been set, the instrument will enter the preset measurement mode
directly.
The completion of the correct power-on and self-inspection indicates that the
electronic load meets the factory standards, and users can use it normally.
Turn off the power button on the front panel and adjust the ON/OFF switch on the rear
panel to OFF when the instrument is not in use.
Note: Please read through the safety information in preface carefully before using
the load.
