Thank you for purchasing this MX2B multimeter.

To obtain the best service from your unit:

• Read these operating instructions carefully,

•

Comply with the precautions for use.

PRECAUTIONS FOR USE

• Never use on a voltage network over 600V with respect to the earth connection.

This voltage surge category III multimeter complies with stringent reliability and

availability requirements, corresponding to fixed industrial and domestic

installations (see IEC 664-1).

• Do not use on alternative and continuous voltages > 600V.

• Indoor use in environments with a maximum pollution level of 2 (cf. IEC 664-1),

temperature of -10°C to +50°C and relative humidity below 90%.

• Respect the value and type of the fuses to avoid damaging the instrument and

cancelling the warranty.

• 1.6A HPC fuse (6.3 x 32mm) 600V - 50kA

• 10A HPC fuse (6.3 x 32mm) 600V - 50kA

• Use accessories corresponding to safety standards (EN 61010 - 031) with 600V

minimum voltage and surge category III.

• Before any measurement, ensure correct positioning of the leads on the

multimeter and of the switch. When the value range of a measurement is not

known, place the switch at the highest calibre, then gradually reduce it until the

appropriate calibre is achieved: the reading should preferably be in the upper 2/3

of the range.

•

Never measure resistances on a live circuit.

• During current intensity measurements (without a clip-on ammeter), stop circuit

power supply before connecting or disconnecting the multimeter or changing

calibre.

• The leads must be disconnected to open the lower half of the MX2B casing.

• Never connect to the circuit to be measured if the casing is not properly closed.
