common safety regulations and operating instruction
should be complied with when using. In order to make
fully use of its functions and ensure safe operations,
please comply with the usage in this section carefully.
In order to avoid personal injury and meter damage
caused by electric shock, the following safety tips should
be paid attention to:
• Don't measure any voltage out of stipulated measuring
range of the meter.
• Don't apply high voltage (above 100V) at input end
when measuring resistance and diode.
• Don't use the meter if the test line is damaged or
exposed metal part.
• Avoid using under direct sunlight or high temperature.
• Pay attention to the possibility of electric shock when
measuring voltage in excess of 36V AC or 48C DC.
• Before measuring current, firstly turn off the power of
measured equipment and measured circuit, Electrify
to measure after connecting test leads.
• Pay attention to battery polarity when changing battery.
