terminal for electrical safety.
Thank you for purchasing this MX1 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).
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 MX1 casing.
Never connect to the circuit to be measured if the casing is not properly
closed.
