Working Voltage:3.5V-6V

Monitoring voltage: 5V/6V

programmable Default monitoring voltage: 5V

Working current: 30mA Silicon wire for large current.

Instruction manual:

1. Meaning of the LED status:

When the switch is turned on, the LED will light as following:

a. 5V monitoring setting mode: the LED on the far left will blink 4 times, turn off the switch while it is blinking, and switch it on again after 2 seconds, the voltage checker will be set to 5V

monitoring mode

b. 6V monitoring setting mode: if you do not turn off the switch while the far left LED is blinking, and then the LED on far right will start to blink, turn off the switch while the LED on right side is blinking, the voltage checker will be set to 6V

monitoring mode

c. Next, the 6 LED lights will light up and turn off in turn back and forth for auto-checking.

d. Then the LED on the far left or far right will blink 3 times quickly, to show the current monitoring mode (the far left LED blink means 5V monitoring and the far right LED blink means 6V monitoring

e. Then this unit will start voltage monitoring, and the LED indicating the current voltage will light up.

(for 5V monitoring, read the upper line of voltage scale, and read the lower line for 6V monitoring)
