Constant Resistance Test - UNI-T UTL8500X Series User Manual

Programable DC Electronic Load User Manual
Operation steps:
1. In initial interface, select [Mode], and then press [CV] to enter the setting interface of
<Constant Voltage CV>.
2. Move the cursor to voltage setting by pulse knob, and press the Enter button
change the voltage value (the value changes from yellow to white) by keyboard or
pulse knob. Press the Enter button
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 users need to stop the load, press the ON button again, and the
running indicator light goes out.

4.1.3 Constant Resistance Test

In CR mode, the electronic load is equivalent to a resistor. It changes the input current as
the voltage changes to maintain a constant resistance value.
