Safety Precautions
1.
Improper use of this meter can cause 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 leads from any voltage source
before replacing the battery or fuses.
4.
Do not exceed the maximum rated input 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 under test before performing Capacitance, Diode,
Resistance or Continuity tests.
7.
Remove the battery from the meter if the meter is to be stored
for long periods.
