1．If the voltage range is unknown beforehand, set the knob to the
highest range, then, select a proper range according to the displaying
value.
2．There is a remained value at small voltage range before measuring, it is
normal and have no effect on measurement. If MSD displays “1”, it
means over range, should set the knob to a higher range.
3．Do not input a voltage over 1000V, or, the circuit might be damaged.
4．Be careful when measuring high voltage circuit.
4-3．ACV MEASUREMENT
3-1．Apply the black test lead to “COM” terminal and the red one to V/Ω
terminal.
3-2．Set the knob to proper ACV range, connect the test leads crossly to
the circuit under tested.
NOTE:
1．If the voltage under tested is unknown beforehand, set the knob to the
highest range, then, select a proper range according to the displaying
value.
2．There is a remained value at small voltage range before measuring, it
is normal and have no effect on measurement. If MSD displays “1” , it
means over range, should set the knob to a higher range.
3．Do not input voltage over 750Vrms，or, the circuit might be damaged.
4．Be careful when measuring high volt circuit.
4-4. DCA MEASUREMENT
1．Apply the black test lead to “COM” terminal, and the red one to mA
terminal (max. 200mA), or red test lead to “20A” terminal（max.
20A）.
2．Set the knob to proper DCA range, connect the meter to the circuit
under tested, the current value and polarity of red test lead connect to
will display on LCD.
NOTE:
1．If the current under tested is unknown beforehand, set the knob to the
highest range, then, select proper range according to the displaying
value.
2．If LCD displays“1”, it means over range, should set the knob to a
higher range.
3．Max. input current is 200mA or 20A（subject to where the rd test lead
apply to）, too large current will blow the fuse. Be careful at 20A,
because 20A is infused, continuously measuring will make the circuit
heat and effect on the accuracy even damaged the meter.
4-5．ACA MEASUREMENT
1．Apply the black test lead to “COM” terminal and the red one to“mA”
terminal（max. 200mA），or apply the red one to “20A” terminal（max.
20A）.
2．Set the knob to proper ACA range, connect the meter to the circuit
under tested.
NOTE:
1．I f the current under tested is unknown beforehand, set the knob to the
highest range, then, select proper range according to the displaying
value.
2．If LCD displays“1”, it means over range, should set the knob to a
higher range.
3．Max. input current is 200mA or 20A（subject to where the rd test lead
apply to）, too large current will blow the fuse. Be careful at 20A,
because 20A is infused, continuously measuring will make the circuit
heat and effect on the accuracy even damaged the meter.
4-6.RESISTANCE MEASUREMENT
1．Apply the black test lead to “COM” terminal and the red one to V/Ω
terminal.
2．Set the knob to proper resistance range; connect test leads crossly to
the resistor under tested.
NOTE:
1．If resistance is over selected range value, “1” displays, should set the
knob to a higher range. When measuring value is over 1MΩ, the
reading will take a few seconds to be stable, it’s normal for high
resistance measuring.
2．When input terminal is in open circuit, overload displays.
3．When measuring in line resistor, be sure that power is turned off and
all capacitors are released completely.
4．Do not input any volt at this range.
4-7．CAPACITANCE MEASUREMENT
1．Apply the knob to proper capacitance range, and insert the capacitor
under tested into “Cx” terminal
2．Connect test leads to the two points of capacitor, be care of polarity if
necessary.
NOTE:
1．If the capacitance under tested is over the max. value of selected range,
LCD displays “1” only, thus, should set the knob to a higher range.
2．It’s normal that there is a remained value on LCD before capacitance
measurement, and it has no effect on measuring.
3．When measuring at large capacitance range, if capacitor is broken or
leakage, LCD displays a value and it’s unstable.
4．Release the capacitor completely before measuring.
4-8．TRANSISTOR hFE
1．Set the knob to hFE range.
2．Verify the transistor under tested is NPN or PNP, insert emitter, base
and collector to proper jack.
4-9．DIODE AND CONTINUITY TEST
1．Apply the black test lead to “COM” terminal and the red one to V/Ω
terminal（the polarity of red lead is “+”）.
2．Set the knob to range, connect test leads to the diode under
tested, the red test connect to diode positive polarity, the reading is
the approx. value of diode forward volt drop.
3．Apply test leads to two points of tested circuit, if the inner buzzer
sounds, the resistance is less than (30±10)Ω.
4-10．DATA HOLD
Press down the key, the present value is hold on LCD, press up the key
and the function is cancelled.
4-11。AUTO POWER OFF
After stop working for 20±10 minutes, the meter will be into sleep mode.
Press “POWER” key twice to restart the power.
4-12．BACKLIGHT INDICATION
Press “B/L” key to turn on the backlight, and press again to turn it off.
5. MAINTANENCE
Do not try to modify the circuit.
NOTE:
1．Do not input a voltage over 1000V DC or 750Vrms AC.
2．Do not measure voltage at Ωrange.
3．Do not take measurement before battery is fit on or rear case is fixed.
4．Remove test leads from testing point and turn power off before
replacing battery or fuse.
5.Keep the multimember dry. Keep the multi-meter away from dust and
dirt
6.Use and store the multi-meter only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices, damage
batteries, and distort or melt plastic part.
7.Handle the multiyear gently and carefully. Dropping it can damage the
circuit boards and case and can cause the multi-meter to work improperly
although the holster can provide enough protection.
8.Wipe the multi-meter with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong detergents
to clean the multi-meter.
9．When “ ” appears on LCD, replace battery as below:
9-1．Release the battery case.
9-2．Take out the old battery and replace a new one. It’s better to use
alkaline battery for long time usage.
9-3．Fix the battery case.
10. FUSE REPLACEMENT ,pls.Use the same type fuse as specified.
10-1．Release the battery case, unfixing the three bolts and open the rear
case.
10-2．Take out the old fuse and replace a new one.
10-3．Fix the rear case and battery case.pls.see the photo to fit on the
holster.
