Warning! Dangerous Voltage (Risk of electric shock).
Caution! Refer to the user’s manual before using this Meter.
Double Insulation (Protection Class Ⅲ).
Alternating Current (AC).
Direct Current (DC).
Either DC or AC.
Ground (maximum permitted voltage between terminal and
ground).
The symbol indicating separate collection for electrical and
electronic equipment.
The RESPONSIBLE BODY shall be made aware that, if the
instrument is used in a manner not specified by the
manufacturer, the protection provided by the instrument may
be impaired.
The finger or any part of your body shall not be beyond
the barrier of the test probe when measuring.
Individual protective equipment must be used if
HAZARDOUS LIVE parts in the installation where
measurement is to be carried out could be ACCESSIBLE.
The following safety information must be observed to insure
maximum personal safety during the operation at this meter.
Do not operate the meter if the body of meter or the test lead
look broken.
Check the main function dial and make sure it is at the correct
position before each measurement.
When making current measurements ensure that the circuit not
“live” before opening it in order to connect the test leads.
Do not perform resistance, capacitance, temperature, diode

2
and continuity test on a live power system.
Do not apply voltage between the test terminals and test terminal
to ground that exceed the maximum limit record in this manual.
Exercise extreme caution when measuring live system with
voltage greater than 60V DC or 30V AC.
Change the battery when the “ ” symbol appears to avoid
incorrect data.
Use the DMM indoor, altitude up to 2000m and temperature 5°C
to 40°C.
Maximum relative humidity 80% for temperatures up to 31°C,
decreasing linearly to 50% relative humidity at 40°C.
1.9 In locations subject to radio frequency interference, the
product may malfunction and it resets automatically when leaving
this environment.

1.SELECT
●Press this button to select your measurement mode.
2.RANGE

5
● When the meter is powered on, the meter is in the auto range mode;
press this button to select a specific measurement range.
● Press this push button more than 2 seconds the meter returns to auto
range.
3.MAX/MIN
● Pressing this button the meter enters the dynamic record mode.
● In the dynamic record mode, pressing this button again cycles MAX,
MIN , AVG , MAX-MIN and Present Reading on.
4. HOLD
● Pressing this button, the meter enters the auto data hold mode and
“H” is displayed on the LCD.
● The data hold function allows the operator to hold a displayed value
on the LCD while the analog bar graph continues to display the updated
value.
● In the auto hold mode the meter can display a new value when a new
and stable value is on the input and the Beeper will sound.
● Pressing this button for more than 1 seconds, the meter exits the
HOLD mode and returns to the normal state.
● Pressing the button for more than 2 seconds turns the backlight
on,look the Selector Knob more clearly, pressing it again turns it off..
5 .REL△
● Pressing this button, the meter enters relative measuring mode,
“REL▲”is displayed on the LCD and the present reading becomes the

6
reference value and displayed on the secondary display. Relative
measurement has two modes. REL▲=measurement value-Reference
value, the other is REL%=(REL▲/Reference value)×100% (press
SELECT to select REL△or REL% mode)..
● Set up reference value for your measurement.
 select your measurement function and your RANGE .
 Press SET once, then press SELECT twice to select the reference
value for a measurement.
● Pressing the REL△ button for more than 2 seconds returns the
meter to normal state.
Pressing the button turns the backlight on, look the Selector Knob more
clearly, pressing it again turns it off.
6. Hz/Duty
pressing the button display the Duty Cycle, pressing it again display
Frepuency.
