1. ATIONSAFETY INFORM SAFETY SYMBOLS

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

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

● 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..

.REL△

● Pressing this button, the meter enters relative measuring mode,

“REL▲”is displayed on the LCD and the present reading becomes the

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

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.

Hz/Duty

pressing the button display the Duty Cycle, pressing it again display

Frepuency.
