1. SAFETY INFORMATION

The following safety information must be observed toinsure
maximum personal safety during the operation atthis meter.
1) When measuring voltage ensure that instrument is not
switched to the current range, resistance range, diode and
continuity range, capacitance range or 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, c apacitance test or temperature test, ensure that the circuit
under test isde-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.
1) Change the battery when the symbol "

1)
D.HOLD/ Back Light key：In any range, push the key, the
present display value will be locked and the " H " symbol will
appear, push it again to exit HOL and the " H"symbol disappear.
Press "D.HOLD" button more than 2 seconds, the back light will light,
press it more than 2 seconds again, the back light will light off.
2) Rotary Switch: use this switch to select functions and ranges.
3) RANGE key：Push the key to select manual mode, push it
again to change the range, press the key for more than 2
seconds to go back auto range mode. But in Hz/Duty and
Capacitance measurement, it can not select manual range mode.
4)
REL key：Push the key, the present display value will be
stored in memory, then the new display value is the difference
between input value and stored data. In Hz/Duty measurement, it
can not work.
5) SELECT key:This key work on the " CAP
Push the key to choose resistance, diode or continuity test.
6） Hz/DUTY key： In Hz range, push the key, you can measure the
duty,push again, go back to Hz measurement. In voltage
range, push it, you can measure Hz and duty, but the
measurement range will be smaller,and the auto range mode
will be changed to manual range mode.
7) LCD Display: LCD Dual Display, facilitates reads the data.
8) V ΩT+ Input Jack 、COM/T- Input Jack
9) Clamp Light easy for test the electric current in hidden place.
