50Hz ~60Hz Digital Clamp Multimeter Relative measurement
Maintenance
1.4.1 Please do not attempt to test lead the shell to adjust or
repair instrument, this operation can only be fully understood by
technicians
1.4.2 Before test leading the instrument bottom shell and the
battery cover, should be removed the test lead from the measured
line test lead
1.4.3 In order to avoid false readings may cause electric shock,
when the instrument display “” symbol,
The battery should be replaced immediately.
1.4.4 Use a damp cloth and a mild detergent to clean the
instrument; do not use abrasive detergents or solvents.
1.4.5 The instrument when not in use should turn off the power,
1.4.6 If you do not use a meter long time, the battery should be
removed to prevent damage to the instrument.
