Safety Precautions

1.Improper useof this metercancause damage, shock, injury or

death. Read and understand this users manual before

operating the meter.

2.Make sure any covers or battery doors are properly closed and

secured.

3.Always disconnect the test leadsfromany voltagesource

before replacing the battery or fuses.

4.Do not exceedthe maximum ratedinput limits.

5.Use great care when making measurements if the voltages are

greater than 25VAC rms or 35VDC. These voltages are

considered a shock hazard.

6.Always discharge capacitors and remove power from the

device undertest before performing Capacitance, Diode,

Resistance orContinuity tests.

7.Remove the battery from the meter if the meter is to be stored

for long periods.
