A.Never use this tester on circuits greater than 60 Hz as the tester may not register voltages over 60Hz B.Always remember that the unit is polarity sensitive and if used on DC circuits reversing the leads may result in high temperatures within the tester. C.Never connect the device to circuits where potentials greater than 120 volts may be present, as the coil's extremely fine wire cannot withstand more than a few amps. D.Always pre-set the meter to the n…
