respect the safety precautions detailed.
SAFETY PRECAUTIONS
Respect the value and the type of fuses or there is risk of
deterioration of the instrument and invalidation of the warranty.
- Fuse 0.5A HBC (500V min - 10kA - 6.3 x 32mm)
- Fuse 12A HBC (600V min - 300kA - 10.3 x 38mm)
Never use on voltage to earth circuits above 600V, with a voltage
surge category of over III, that is to say, fixed industrial and
domestic installations (ref. IEC 664-1).
To be used indoors in environments with a maximum pollution
degree of 2 (ref. IEC 664-1), a temperature between 0 and 50°C
and relative humidity below 70%.
Use accessories which conform to safety standards
(IEC 1010-2-031), with a minimum voltage of 600V and a voltage
surge of category III.
Never open the multimeter case before disconnecting from any
electrical source.
Never connect up to a circuit to be measured if the multimeter
case is not closed correctly.
Before any measurements are taken, ensure the leads and switch
are in the correct positions.
Never measure resistances on a circuit with the power switched
on.

- digital 4000 counts and 42 segment bargraph
- automatic or manual range selection
- auto off after 30 minutes without action on a control or function
- possibility of permanent operation (see HOLD)
Various measurement accessories broaden the scope of application
or provide the multimeter with new functions.
See the list of accessories and references on the “To Order” page
(Documentation upon request).
Note : Always use accessories suitable for the voltage and the
