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.

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. H / 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 H / 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.
   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.

Warning
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.

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.

Auto Power Off
The meter will automatically shut itself off after
approximately 30 minutes without operation.

OPERATION

This instrument has been designed and tested in accordance with IEC 61010, Safety Requirements for 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 UNINSULATED CONDUCTORS AT A VOLTAGE GREATER THAN 600V AC/DC.

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)

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.

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.
