of the screen (UTL8212 only).

2. Press Shift +Mode to enter the main menu interface.

3. Use the knob to select the parameter setting, and then press Enter to enter the

parameter setting interface.

4. Use the knob to set the short circuit time, and press Enter to complete the setting.

5. Press the Mode button to enter the mode selection interface, select the CC/CV/CP/

CR mode, press Shift+

→(short) to enter the short circuit mode, and the symbol [Short]

will appear. Set the corresponding current value with the knob and press the

ON1/ON2 button to complete the short circuit test.

4.3 Parameter Input and Operating Control

4.3.1 Parameter Input

There are two ways to input parameters: rotate the knob or press the direction buttons.

When the set parameter is out of range, it will not be saved by pressing Enter. Please

reset the correct parameter.

4.3.2 Operating Control

After the electronic load is powered on, it is in an unloaded status. Control the input switch

of the load by pressing the ON1/ON2 button on the front panel. When the ON button

indicator light is on, it means it is in the loaded status, and when the ON button indicator

light is off, it means it is in the unloaded status.

4.4 Alarm Prompts

1. Overvoltage protection: load input voltage is higher than the set value of overvoltage

protection.

2. Overcurrent protection: load current is higher than the set value of overcurrent

protection.

3. Power protection: the load power is higher than the set value of over power

protection.

4. Polarity error: The positive and negative poles of the load input terminal are reversed.

5. Undervoltage protection: When the load is operating, it is detected that the input

voltage is lower than the unloading voltage set value.

6. Data overrange: The data entered is out of range (the upper limit of parameters such

as voltage/current/power/time).

7. Position error: If the voltage position/current position is set to the low position, when

the voltage/current value exceeds the range of the low position during load operation,

the error information will be displayed. The users should return to the parameter
