!Safety Information

• Individual protective equipment must be used if

hazardous live parts in the installation where measure

ment is to be carried out could be accessible.

• The barrier on the JAW is indicating the limit of safe

access of the hand-held part, do not over the barrier

when in normal use.

• Do not use a flexible current sensor if the inner

contrasting color of the insulation of the flexible cord is

visible.

• If the equipment is used in a manner not specified by the

manufacturer, the protection provided by the

equipment may be impaired.

• To avoid false readings that can lead to electric shock

and injury, replace battery as soon as low battery

indicator blinks.

• Do not use Meter around explosive gas or vapor.

• Remove test lead from Meter before opening the battery

door or Meter case.

• Use caution with voltages above 30 Vac rms, 42 Vac

peak, or 60 Vdc. These voltages pose a shock hazard.

• Probe assemblies to be used for MAINS measurements

shall be RATED as appropriate for MEASUREMENT

CATEGORY III or IV according to IEC 61010-031 and

shall have a voltage RATING of at least the voltage of

the circuit to be measured.

Caution

• Disconnect the test leads from the test points before

changing the position of the function rotary switch.

• Never connect a source of voltage with the function

rotary switch in resistance, diode, continuity, and

capacitance position.

• Do not expose Meter to extremes in temperature of high

humidity.

1-1 Unpacking and Inspection

Upon removing your new Digital Clamp Multimeter from its

packing, you should have the following items:

1. Digital Clamp Multimeter.

2. Test lead set (one black, one red).

3. Carrying case.

4. Instruction manual.

5. Battery.

1-2 Front Panel

Refer to Figure 1 and to the following numbered steps to

familiarize yourself with the meter’s front panel controls

and connectors.

1. Digital Display — The digital display has a 3 3/4 digit

LCD readout (maximum reading 3999) plus decimal

point , AC, DC, AUTO, HOLD, MAX , and unit

annunciators.

2. Input Terminal — The black test leads is always

connected to the “COM” input terminal and red test lead is

always connected to the “V-Ω” input terminal when

measuring ACV or DCV or RESISTOR or CONTINUITY.

3. Drop-Proof Wrist Strap — Prevents the instrument

from slipping off the hand while in use.

4. Function Switch — This slide switch is used to select

V, V, A, A, Ω , function.

5. / MAX Switch — This switch has two modes one is

data hold the other is maximum hold .

Sliding the function switch to power on , this switch will

work in data hold mode. Pressing the / MAX Switch

then slide the function switch from power off to power on ,

this switch will work in maximum hold mode.

Data hold mode — This mode is used to hold measured

value for all functions , push this switch then AUTO

annunciator is displayed, Conversions are made but the

display is not updated.

Warning

!

30R EN

Maximum hold mode — This mode is used to hold the

maximum measured value for all functions.

Press this switch the "MAX" annunciator turns on then

enters the maximum hold mode.

Press this switch again to restart recording. Press this

switch more than 1 seconds to exit the maximum hold

mode.

6. ZERO Switch —This switch is used to ZERO the

reading on display.

7. Ω / / AC / DC Selection Switch — Push the " Ω /

/ AC / DC " switch alternately to measure AC voltage or

DC voltage in the " V " function or to measure AC

current or DC current in the " A " function or to measure

resistor or continuity in " Ω " function.

8. Trigger — Press the lever to open the transformer

jaws. When the pressure on the lever is released , the

jaws will close again.

9. Hand Guard — Designed to protect user for safety.

10. Transformer Jaws — Designed to pick up the AC/DC

current flowing through the conductor.

When connecting the test leads to the DUT (Device Under

Test) connect the common test leads before connecting

the live test leads; When removing the test leads, remove

the live test leads before removing the common test leads.

following. Original Accuracy + 10 digitals/ change steps of

range .

For example :

At First , the maximum hold reading on display is 100.0mV

on 400.0mV range. f a voltage vibration changes the

maximum hold reading to 120.0V. The change steps of

range are 3 steps ( 400.0mV to 4.000V to 40.00V to

400.0V) so the accuracy is needed to add 3 steps x 10

digitals / change steps of range = 30 digits.

Electronic Measuring Apparatus and has been supplied in

a safe condition. This instruction manual contains some

Information and warnings which have to be followed by

the user to ensure safe operation and to retain the

instrument in safe condition.

3-1 Preparation and Caution before

Measurement

1. If the meter is used near equipment that generates

electro-magnetic interference, the display may be

unstable or indicate incorrect measurement values.

2. Make sure that the battery is properly connected.

3. The instrument should only be operated between 0°C

50°C and at less than 80% R.H. except current

function is operated between 0°C 40°C .

4. Do not use or store this instrument in a high tempera

ture or high humidity environment and do not store the

unit in direct sunlight.

5. Do not replace battery with power on condition.

6. If the unit is not to be used for a long period of time ,

remove the battery.

7. Do not forget to turn off after use.

8. Maximum rated voltage to earth for voltage

measurement terminals is 600V CAT.II , 300V CAT. III

THIS INSTRUMENT MUST NOT BE USED ON

Figure 2

3-2 AC/DC Current Measurement

1. Set the slide switch at " A " position.

2. Open Spring-loaded clamp by pressing trigger on left

side of meter.

3. Position clamp around wire or conductor and release

clamp trigger smoothly , do not release quickly, make

sure that the clamp is entirely closed. Position the

conductors at the center of the clamp jaws for accurate

measurement . The clamp must be positioned around

only one conductors of a circuit.

If the clamp is placed around two or more current-carry

ing conductors , the meter reading will be FALSE.

4. For DC measurement , the reading is positive value

when the current flows from the upper side to the lower

side of the instrument as Fig. 2.

5. Using the zero switch to zero the reading. Due to the

high sensitivity of the clamp meter, must zero in the

same direction as in measurement to avoid interference

by external magnetic field. (see Fig.3)

30R EN

3-3 AC/DC Voltage Measurement

1. Set the slide switch at " V " position.

2. Connect the black test lead to the "COM" terminal on

the bottom of the meter and the red test lead to the

" V-Ω" terminal . You can now place the test probes on

the conductors to make the measurement.

3. Pushing the AC/DC switch to select AC mode or DC

mode.

30R EN

3-4 Resistance Measurement

1. Set the slide switch at " Ω " position.

2. Connect the black test lead to the "COM" terminal and

red lead to the " V-Ω" terminal.

3. Verify that the power to the circuit under test is off.

Connect test leads to the circuit to make the measure

ment.

4. Pushing the Ω / switch to select Resistance mode or

Continuity mode.

5. At mode, Built - in buzzer sounds if the resistance of

the circuit under test is less than 50Ω.
