2. The tip of the test pen is metal, do not touch it with hands during
measurement, otherwise it might cause electric shock and affect
measurement results.
3. Before test, please check measurement range and socket into which the test
pen is inserted, perform test after checked with no error.
4. If it is unable to estimate measured value, choose max measurement range,
and shift to suitable range based on measured results.
5. It is strictly forbidden to shift measurement range when measuring
high voltage or large current, as it can cause electric arc to burn switch
contact. If you want to change range, please disconnect metal contact
tip first.
6. To avoid instrument damage, it is strictly forbidden to measure
resistance when tested circuit is powered on.
7. When you want to measure DC current with multimeter, please reset it to
zero first, then select suitable measurement range. Current varies in
different modules, please refer to module mark to shift measurement range.
During measurement, connect the multimeter in series, and measure circuit
one by one. The bypass voltage can be disconnected. Please be aware that
parallel connection of multimeter is forbidden, as it can cause multimeter
damage and personnel injury.
