1. LCD Display: In normal mode, the upper line of the LCD screen displays the load input voltage and load temperature; the lower line displays the load current, power, capacity and discharge time. In protection mode, the LCD screen displays the protection code. In setting mode, the LCD screen displays the various setting parameter codes and parameter thresholds. 2. Load current adjustment: The discharge current can be adjusted by the potentiometer. 3. Sound and light alarm: When the load is turned on, the RUN indicator light is always on and the buzzer does not sound; when the load is turned off, the RUN indicator light is not on and the buzzer does not sound. After entering the protection mode, the buzzer beeps and the RUN indicator light flashes. 4. Intelligent fan cooling: It automatically starts when the load discharge power is greater than 10W or the load temperature is greater than 40℃. 5. Complete software and hardware protection mechanism, and the software protection threshold can be adjusted. After software protection, the output is turned off. Hardware protection: Both the module power supply port and the load input port have anti-reverse connection protection. Software protection: OVP overvoltage protection OCP overcurrent protection; OPP overpower protection OTP overtemperature protection LVP undervoltage protection The load is turned off by default. Press the ON/SET button to start or turn off after power-on. All settable parameters can be stored after power-off. Color:Blue Material:ABS Package Contents: 1 * FX2535 constant current tester
