3. General Guidelines

Refer to the Velleman® Service and Quality Warranty on the last pages of this manual.

4. Maintenance

There are no user-serviceable parts inside the device. Refer to an authorized dealer for service and/or spare parts. Before performing any maintenance activities, disconnect the test leads from the jacks. For instructions on replacing the battery or fuse, refer to §11 Battery and fuse replacement. Do not apply abrasives or solvents to the meter. Use a damp cloth and mild detergent for cleaning purposes.

5. During Use

Risk of electric shock during operation. Be very careful when measuring live circuits.

  • Never exceed the limit value for protection. This limit value is listed separately in the specifications for each range of measurement.
  • Do not touch unused terminals when the meter is linked to a circuit, which is being tested.
  • Never use the meter with CAT III installations when measuring voltages that might exceed the safety margin of 600 V above earth ground.
  • Set the range selector at its highest position if the intensity of the charge to be measured is unknown beforehand.
  • Disconnect the test leads from the tested circuit before rotating the range selector in order to change functions.
  • When carrying out measurements on a TV set or switching power circuits, always remember that the meter may be damaged by any high amplitude voltage pulses at test points.
  • Always be careful when working with voltages above 60 VDC or 30 VAC RMS. Keep your fingers behind the probe barriers at all times during measurement.
  • Never perform resistance, diode, or continuity measurements on live circuits. Make sure all capacitors in the circuit are depleted.
  • Always hold the device behind the finger guard (see General Description, nr. 12).
  • Comply with the local and national safety regulations. Use personal protective equipment, such as approved rubber gloves, face protection, and flame-resistant clothing, to prevent shock and arc blast injury where hazardous live conductors are exposed.
  • Do not use this device to measure a current with a frequency above 1 kHz.
  • Only use this device as specified in this manual in order not to compromise the protection supplied by the device.

7. Overvoltage/Installation Category

DMMs are categorized depending on the risk and severity of transient overvoltage that might occur at the point of the test. Transients are short-lived bursts of energy induced in a system, e.g. caused by a lightning strike on a power line.

The existing categories according to EN 61010-1 are:CAT IA CAT I-rated meter is suitable for measurements on protected electronic circuits that are not directly connected to mains power, e.g. electronics circuits, control signals…

CAT IIA CAT II-rated meter is suitable for measurements in CAT I environments and mono-phase appliances that are connected to the mains by means of a plug and circuits in a normal domestic environment, provided that the circuit is at least 10 m apart from a CAT III- or 20 m apart from a CAT IV-environment. E.g. household appliances, portable tools…

CAT IIIA CAT III-rated meter is suitable for measurements in CAT I- and CAT II-environments, as well as for measurements on (fixed) mono or poly-phased appliances which are at least 10 m apart from of a CAT IV environment, and for measurements in or on distribution level equipment (fuse boxes, lighting circuits, electric ovens).

CAT IVA CAT IV-rated meter is suitable for measuring in CAT I-, CAT II- and CAT III environments as well as on the primary supply level. Note that for all measurements on equipment for which the supply cables run outdoors (either overhead or underground) a CAT IV meter must be used.

Warning:This device was designed in accordance with EN 61010-1 installation category CAT III 600 V. This implies that certain restrictions in use applications are related to voltages and voltage peaks which can occur within the environment of use. Refer to the table above.

This device is only suitable for measurements up to 600 V in CAT III

8. Pollution Degree

IEC 61010-1 specifies different types of pollution environments, for which different protective measures are necessary to ensure safety. Harsher environments require more protection, and the protection against the pollution which is to be found in a certain environment depends mainly on the insulation and the enclosure properties. The pollution degree rating of the DVM indicates in which environment the device may be used.

Pollution degree 1No pollution or only dry, nonconductive pollution occurs. Pollution has no influence. (only to be found in hermetically sealed enclosures)

Pollution degree 2Only non-conductive pollution occurs. Occasionally, temporary conductivity caused by condensation is to be expected. (home and office environments fall under this category)

Pollution degree 3Conductive pollution occurs, or dry non-conductive pollution occurs that becomes conductive due to condensation that is to be expected. (industrial environments and environments exposed to outside air – but not in contact with precipitation)

Pollution degree 4The pollution generates persistent conductivity caused by conductive dust or by rain or snow. (exposed outdoor environments and environments where high humidity levels or high concentrations of fine particles occur)

Warning: This device was designed in accordance with EN 61010-1 pollution degree 2. This implies that certain restrictions in use applications are related to the pollution which can occur within the environment of use. Refer to the table above.This device is only suitable for measurements in Pollution degree class 2 environments.

11. Battery Replacement

WARNING: To avoid electrical shock always disconnect the test leads prior to opening the housing. To prevent fire hazards, only use fuses with the same ratings as specified in this manual.Remark: refer to the warning on the battery compartmentThere are no user-serviceable parts inside the device. Refer to an authorized dealer for service and/or spare parts.Disconnect the test leads from the test points and remove the test leads from the measuring terminals before replacing the batteries or fuses.

  • When” -+” is displayed, the battery should be replaced.
  • Fuses rarely need replacement and blown fuses almost always result from human error.To replace the battery:
  • Switch of the meter.
  • Remove the screw at the back of the case and gently open the housing.
  • Remove the old battery and insert a new one.
  • Close the housing and fasten the screw.Battery: 3x AAA/LR03, make sure to respect the polarity

12. Troubleshooting

If the device acts abnormal while measuring, this means that the internal fuse is defective. Keep in mind that a low battery level could lead to incorrect measurements. Replace the battery on a regular basis. (tip: the reduced luminosity of the backlight/LCD display indicates a low battery level)
