WARNING
Do not make measurements of power lines carrying more than 250V.
IN SOME CASES, POWER LINES MAY CARRY VOLTAGE SPIKES OF
SEVERAL TIMES OF THE NORMAL SUPPLY VOLTAGE. THIS
INSTRUMENT SHOULD NOT BE USED TO MEASURE POWER LINES.
* The term of “POWER LINE” means the electrical circuit providing the
power to factories, buildings and etc.
