Shanghai Lightning Counter Calibrator Manufacturer 

1.Before using the lightning counter calibrator, please charge it first. To ensure charging effectiveness and extend battery life, use the dedicated charger. It takes about 3-4 hours to fully charge an empty battery. The red light on the charger indicates charging; the green light indicates charging is complete.

2、According to the installation height of the counter, properly extend the telescopic discharge rod.

3、For the dedicated grounding wire, insert one end's plug into the jack at the rear of the calibrator, and connect the other end's clip to the ground.

4、Press the red button to turn on the high voltage for about 1 second, the indicator light will light up (flicker slightly),

then gently click the connection end between the counter and the lightning arrester for testing.

5、After each click, the discharge rod tip should be removed from the counter. If repeated testing is needed, do not release the button. Wait 1-2 seconds until the indicator light flickers again, then click to test again.

6、Continuous testing may cause the calibrator to heat up. Please allow appropriate intervals to reduce malfunctions and extend battery life.

7、The calibrator output has three levels: high, medium, and low, which can be adjusted via the toggle switch on the head to suit testing different types or brands of counters.

8、If the indicator light does not flash after pressing the button for more than 3 seconds, the battery needs to be charged.

9、Do not disassemble the calibrator arbitrarily. If the battery pack capacity significantly drops or charging efficiency is too low, it needs to be replaced. Please purchase a dedicated battery pack from our company.
