• Do not test voltage exceeding rated voltage marked on the meter
(600V).
• When testing voltage exceeding 30V AC voltage RMS, 42V AC peak
or 60V DC, be particularly careful to avoid electric shock.
• When measuring, use correct jack, and select the proper function.
• Do not use the meter in explosive gas, vapor or dusty environ-
ments.
• When using the probe, fingers should be behind the probe protec-
tion device.
• Before measuring resistance, continuity, first turn off power and
discharge all high voltage capacitors.
• If the meter is not used in accordance with the instructions, the
meter’s safety protective function may become invalid.
