Safety
This symbol adjacent to another symbol, terminal or operating
device indicates that the operator must refer to an explanation in
the Operating Instructions to avoid personal injury or damage to
the instrument.
This symbol advises the user that the terminal(s) so marked
must not be connected to a circuit point at which the voltage with
respect to earth ground exceeds (in this case) 600 VAC or VDC.
This instrument has been designed for safe use, but must be operated with
caution. The rules listed below must be carefully followed for safe operation.
1. NEVER apply voltage or current to the meter that exceeds the specified
maximum:
2. USE EXTREME CAUTION when working with high voltages.
3. DO NOT measure voltage if the voltage on the "COM" input jack exceeds
1000V above earth ground.
4. ALWAYS turn off the power and disconnect the test leads before opening
the covers to replace the fuse or batter
5. If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

NON-CONTACT VOLTAGE (NCV) :
The NCV function works on any rotary switch position.
1.Test the detector on a known live circuit before use.
2.Hold the top of the meter very close to the voltage source as shown.
3.If voltage is present, the back light will flash a bright red.

Operating Instructions
Nut Function:
Rotate the nut, the metal probes can hide in the head of the instrument.
Button function:
Mode button: Chose DC/AC when you Measure voltage or Current , Chose resistance,
diode , continuity when you measure resistance, diode , continuity.
Range button: manual change range or Auto change range.
Hold button: Freeze the current test value.
Power OFF:
Rotate the function switch to the character “OFF”on the instrument for Turnning off
the power
DC/AC VOLTAGE MEASUREMENTS
CAUTION: DO not measure DC/AC voltages if a motr on the circuit is being switched ON or
OFF. Large voltage surges may occur that can damage the meter.
Rotate the function switch to the character “”on the instrument , press Mode
Button to choose DC or AC Voltage , Touch the black test probe tip to the negative side
of the circuit. Touch the metal probe tip to the positive side of the circuit. Read the voltage
in the display.
RESISTANCE MEASUREMENTS
Rotate the function switch to the character “”on the instrument
1.Press the MODE button to change “ “’’, “ ”on the display.
2.If the resistance is less than approximately 30
3.Touch the test probes to the diode under test. Forward voltage will typically indicate
0.400 to 0.700V. Reverse voltage will indicate “OL”. Shorted devices will indicate near 0V
and an open device will indicate “OL” in both polarities.
DC/AC CURRENT MEASUREMENTS
CAUTION: Do not make more than 400mA current measurements for
longer time . it will damage the instruction.
Rotate the function switch to the character “ ” on the instrument, press Mode
Button to choose DC or AC Current , Touch the black test probe tip to the negative side
of the circuit. Touch the metal probe tip to the positive side of the circuit. Read the voltage
in the display.
NON- CONTACT VOLTAGE
Rotate the function switch to the character “NCV”on the instrument, let the head of the
instrument near the meausred matter, if the voltage of the matter more than 50V ,the
NCV indication will light.

Auto Power Off
When the function switch isn’t rotated and the button of the instrument isn’t pressed
after 15 minutes, the instrument will turn off the power (in the sleeping). In this mode if you
press any button or rotate the function switch, the instrument will work (be awaking).
When you rouate the function switch to turn on the power, the auto power off
symbols “”will show the LCD display. Before instrument will auto power off, it
announce you by sound five beep
Battery replace:
WARNING: To avoid electric shock, disconnect the test leads from any
source of voltage before removing the battery cover.
1.Turn power off and disconnect the test leads from the meter.
2.Open the rear battery cover by removing one screw using a screwdriver.
3.Insert the battery into battery holder, observing the correct polarity.
4.Put the battery cover back in place. Secure with the screws.
WARNING: To avoid electric shock, do not operate the meter until the
battery cover is in place and fastened securely.
NOTE: If your meter does not work properly, check the fuses and batteries to replace.
Replacing the fuses
WARNING: To avoid electric shock, disconnect the test leads from any source of
voltage before removing the meter cover.
make sure that they are still good and that they are properly inserted.
1. Gently remove the old fuse and install the new fuse into the holder.
2. Always use a fuse of the proper size and value (0.5A/250V fast blow for
the 400mA range .
3. Replace and secure the rear cover, battery and battery cover.
WARNING: To avoid electric shock, do not operate your meter until the fuse
cover is in place and fastened securely.
