• No part of the instrument or its accessories may be replaced by any parts other than parts certified by the manufacturer or the manufacturer’s suppliers.

Attention!

• The test instrument must only be used for the specified measurement range.
• Each time before use, inspect the instrument to ensure that it is working faultless-ly (for example, on known source of voltage). Please also refer to DIN VDE 0105, Part 1.
• The Responsible body or operator should refer to the instruction manual to pre-serve the protection afford by the equipment. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
• Any parts of the device and its accessories are not allowed to be changed or re-placed, other than authorized by the manufacturer of his agent.

Caution!
The instrument must only be used under the conditions and for the purposes for which it was designed and built. Thus, it is imperative to observe the notes on safe-ty, the technical data in conjunction with the ambient conditions and use the in-strument in dry conditions.

Maintenance
The instrument does not require special maintenance when used as specified in this operation manual.

3. General data

The accuracy relates to 1 year at a temperature between 18 °C – 28° and 75 % humidity (yearly calibrations are offered).

Autoranging and manual measurement range selection
Max. voltage between the connection socket and ground: 300 V DC/AC

Definition of measurement categories.
Measurement category II: Measurements on circuits directly connected to low volt-age networks electrically via plug. Typical short-circuit current < 10 kA.

Measurement category III: Measurements within the building installation (stationary consumer devices with non-plug-in connection, distributor connection, permanently installed equipment in the distributor). Typical short-circuit current < 50 kA.

Measurement category IV: Measurements at the source of the low voltage installa-tion (meters, mains connection, primary overcurrent protection). Typical short-circuit current >>50 kA.

To establish the measurement category in a combination of test lead and measur-ing instrument, the lowest category, either of the test lead or the measuring instru-ment, always applies.

4. Application description

DC VOLTAGE MEASUREMENT
Set the selector switch to measurement range V=.
Insert the black test lead into the ‘COM’ socket and the red test lead into the right-hand socket. Using the test probes, touch the test points of the test object.

The multimeter automatically searches for the most suitable measurement range. Read measurement value on the display.

AC VOLTAGE MEASUREMENT
Set the selector switch to measurement range V~.
Insert the black test lead into the ‘COM’ socket and the red test lead into the right-hand socket. Using the test probes, touch the test points of the test object.
The multimeter automatically searches for the most suitable measurement range. Read measurement value on the display.

The red test lead can be used for single-pole phase test by pressing the M-button, the display will flash and acoustic signal is emitted. Before the test, make absolute-ly sure to disconnect all other test leads. This test is not suitable for determining the presence of hazardous line voltage. During the test, even if display does not flash and no acoustic signal is emitted, a dangeous high voltage (>33 V AC or 70 V DC) may nevertheless be present.

Caution!
Before touching conductive parts the absence of hazardous voltage must be checked with the two-pole direct contact measurement of the AC-Voltage range.

CABLE BREAK DETECTION
The cable break detection is intended for non-contact localization of cable breaks on non-exposed live lines.

Set the selector switch to CABLE BREAK DETECT function.

When sensor on the top edge of the multimeter is held over a live cable (100 – 300 V AC) starting from the feeding point while the M-button is held pressed down, the display flashes and an acoustic signal is emitted before breaking point.

When carrying out the cable break detection, if the display does not flash and no acoustic signal is emitted, a dangerous high voltage (>33 V AC or 70 V DC) may nevertheless be present. The non-contact sensor can only detect voltage generat-ed by sufficiently strong electric fields from power sources (grids,

100 V AC). If the field strength is low, the instrument may not detect applied voltage and thus cannot locate the cable break correctly. If the instrument does not detect any existing volt-age, this can be due to the following factors, amongst other things:

• Shielded wires/cables
• Thickness and type of insulation
• Distance from the voltage source

Exercise caution at voltages above 30V, as there is a risk of electric shock.

Caution!
The non-contact cable break detection function is not suitable for the detection of hazardous line voltage.

Before touching conductive parts the absence of hazardous voltage must be checked with the two-pole direct contact measurement of the AC-Voltage range.

All equipment subject to this directive is marked with this logo.

Disposal of used batteries

As end user, you are legally obliged (battery law) to return all used batteries; disposal by the household waste is forbidden!

Batteries containing contaminant material are labelled with this symbol
indicating that they may not be disposed of in normal domestic waste.
The designations for the essential heavy metals are, amongst others:
Cd = Cadmium, Hg = Mercury, Pb = Lead, Mn = Manganese, Li = Lithium.

You can return your used batteries to collection points in your community or anywhere where batteries are sold free-of-charge.
