DIGITAL DUAL DISPLAY AC CLAMP MULTIMETER
OPERATION MANUAL
This LCD Auto Range & Auto Power off Digital AC clamp multi
meter is a portable, 3 1/2-digit multi meter. It is ideally suited for
field, laboratory, shop and home applications.

1. SAFETY INFORMATION

The following safety information must be observed to in sure
maximum personal safety during the operation at this meter.
1) When measuring voltage ensure that instrument is not switched
to the current range, resistance range, diode and continuity range,
temperature range.
2) Use extreme care when measuring voltage above 50V.
especially from sources where high energy is existed.
3) Avoid making connections to "live" circuits whenever possible.
4) Before making resistance measurements, diode or continuity
test, temperature test, ensure that the circuit under test is
de-energized.
5) Always ensure that the correct function and range is selected.
6) Extreme care should be taken when using the instrument to
conjunction with a current transformer connected to the terminals if
an open circuit occurs.
7) Ensure that the test leads and probes are in good condition with
no damage to the insulation.
8) Take care not to exceed the over-load limits as given in the

specifications.

9) Before opening the cover of the battery cabinet to replace
batteries. disconnect the test leads from any external circuit, set
the selector switch to "OFF" position.
10) Keep the fingers after the protection ring when measuring
through the instrument lead.
11) Change the battery when the symbol "
incorrect data.
