1. SAFETY INFORMATION
The following safety information must be observed to insure
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, 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, capacitance test or 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 “ ” appears to avoid
incorrect data.

1) Rotary Switch: use this switch to select functions and ranges.
2) 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 HOLD 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.
3) SELECT key:This key work on the "CAP Ω" range , Push
the key to choose resistance, diode ,continuity or capacitance
test. And on the voltag or current range,change to DC/AC.
4) 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.
5) Hz/DUTY key：In “
V
/H z
” or “
4 0 0 A
/1 0 0 0 A
” range,
push the key, you can measure the Hz ,push again, can
measure the duty.
6）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.
7) LCD Display：LCD Dual Display, facilitates reads the data.
