8. Measuring with the 03&
8.1 Preparation for measurement
Store and use the MPC2 only under the correct temperature conditions stated. Always avoid longer exposure to sunlight.
- Check the rated voltage and current stated on the safety measuring wires with tips. The rated voltage and current of the safety measuring wires and tips comply with the MPC2.
- Check the insulation of the measuring wires and tips. If the insulation is damaged, replace the testing measuring wires immediately.
- Check the continuity of the safety measuring wires. If the wire is disconnected at any point, remove it immediately.
- Before selecting another function with the sliding switch or the function button , the safety measuring wires and tips must be disconnected from the measuring point.
- Strong sources of interference close to the MPC2 may produce unstable readings and measurement errors.
8.2 Voltage measurement
Always observe the maximum voltage to earth potential!
Electrical hazard!
The maximum voltage which may be applied to the sockets of the MPC2
- COM socket, black ,
- V- socket (positive) for voltage and resistance measurements and continuity testing (marked red) against earth potential, is 600 V.
- Select the desired function with the sliding switch and the function button of the MPC2.

- Contact the black safety measuring wire with the COM-socket (black).
- Contact the red safety measuring wire with the V- socket (red).
- Bring the black and red measuring tips into contact with the measurement points. Read the measurement value on the digital display .
Note:
- In small voltage measuring ranges, the zero-volt indication does not appear (due to interference) when the safety measuring wires are open. Make sure that the MPC2 is fully functional by short-circuiting the measuring tips.
See fig. 2: DC-voltage measurement See fig. 3: AC-voltage measurement
8.3 Resistance measurement
- Select the desired function with the sliding switch and the function button of the MPC2.
- Contact the black safety measuring wire with the COM-socket (black).
- Contact the red safety measuring wire with the V- socket (red).
- Bring the black and red measuring tips into contact with the measurement points. Read the measurement value on the digital display .
Note:
- To obtain a correct measurement, ensure that no voltage is applied to the measuring point.
- With small resistances, the measuring result can be improved by measuring the resistance of the safety measuring wires beforehand by short-circuiting the measuring tips and subtracting the reading obtained from the resistance measured.
See fig. 4: Resistance measurement
8.4 Continuity testing with buzzer
- Select the area marked with the buzzer symbol with the sliding switch and the function button of the MPC2.
- Contact the black safety measuring wire with the COM-socket(black).
- Contact the red safety measuring wire with the V- socket (red).
- Bring the black and red measuring tips into contact with the measurement points. If the resistance between the measurement points is less than 50 , the buzzer incorporated in the MPC2 sounds.
See fig. 5: Continuity testing with buzzer
8.5 Current measurement
8.5.1 Preparation for measurement
Store and use the MPC2 only under the correct temperature conditions stated. Always avoid long exposure to sunlight.
- Strong sources of interference close to the MPC2 may produce unstable readings and measurement errors.
Do not apply voltage to the output contacts of the 03&. If necessary, remove the safety measuring wires connected.
When measuring DC current, observe correct polarity.
8.5.2 Current measurement
- Select the desired measuring function with the sliding switch and the function button .
- Press the “ZERO” button to set the MPC2 to the starting point.
- Operate the opening lever . Grip the single wire containing the current to be measured with the prongs of the MPC2.
- Read the value in the digital display .
See fig. 6: AC/ DC current measurement
9. Maintenance
Before opening the 03&, ensure that it is not
connected to a source of voltage! Electrical hazard!
Any work required on the MPC2 when it is under voltage must be done only by a qualified electrician. Special steps must be taken to prevent accidents. Before opening the MPC2, remove it from all sources of voltage as follows:
- Remove first the black and the red measuring tip from the measurement object.
- Then remove the black and red safety measuring wires from the
2008 Pinces-multimetre-MPC2-mpvnotice.pdf
www.motor-pump-ventilation.com
MPC2.
- Move the sliding switch to the position “OFF”.
9.1 Making the unit safe
Under certain circumstances, the safety of the MPC2 can no longer be guaranteed. This may be the case if:
- there are visible signs of damage on the unit,
- errors occur in measurements,
- the unit has been stored for a long period of time under the wrong conditions, and
- if the unit has been subjected to rough handling during transport.
In these cases, the MPC2 must be switched off immediately, removed from the measuring points and secured to prevent it from being used again.
9.2 Cleaning
Clean the outside of the unit with a clean dry cloth. (Exception: any type of special cleaning cloth). Never use solvents or abrasives to clean the clamp meter. Ensure that the battery compartment and the battery contacts have not been contaminated by electrolyte leakage. If any electrolyte or white deposits are seen in the battery compartment or battery housing, remove these with a dry cloth.
9.3 Battery replacement
Before opening the MPC2, ensure that it is not
connected to a source of voltage! Electrical hazard!
The MPC2 is powered by two 1.5 V batteries. The batteries must be replaced (see fig. 8) when the battery symbol appears in the display . To replace the batteries, proceed as follows:
- Remove the black and red measuring tips from the measurement circuit.
- Remove the black and red safety measuring wires from the MPC2.
- Lay the MPC2 on its front and unscrew the screw on the cover of the battery compartment.
- Push the cover of the battery compartment to the side out of its guide.
- Remove the discharged batteries from the battery holder.
- Insert the new batteries into the battery holder. Make sure that they are connected to the correct battery poles.
- Push the cover of the battery compartment into its correct position and replace the screw.
See fig. 7: Replacing the batteries.
Remember the environment! Do not dispose of used batteries with domestic waste. Dispose of them at a battery-collection
point or as toxic waste. Your local authority will give you the information you need.
9.4 Calibration
To maintain the specified precision of the measurement results, the instrument must be recalibrated at regular intervals by our factory service. We recommend a recalibration interval of one year. Send the appliance to the following address:
