Intended Use - VOLTCRAFT Multi-DMM MT-52 Notice D'emploi

Intended Use

- Measuring and displaying electric parameters in the range of excess voltage category III (up to max.
600V against ground potential, pursuant to EN 61010-1) and all lower categories. The measuring
device and equipment must not be used in the overvoltage category CAT IV (e.g. at the low voltage
installation source.)
- Measurement of direct and alternating voltage up to a maximum of 600 V
- Measurement of direct and alternating current up to 10 A
- Measuring resistance values of up to 40 MΩ
- Continuity test (< 50 Ω acoustic)
- Diode Test
- Capacity measuring up to 100 µF
- Frequency measurement up to 10 MHz
- Pulse width display in %
- Temperature measurement with external K-type sensor from -20 to +1300 °C
- Temperature measurement with internal sensor from 0 to +50 °C
- Measuring the relative air humidity form 33 - 99 %
- Measuring the illumination strength up to 40 000 Lux
- Measuring the noise level of 35 - 100 dBC (for orientation measurement)
- Contact-free AC voltage detection "NCV"
The measurement functions are selected using the dial switch. Except for the environmental measuring
ranges of temperature, humidity, noise level and illumination strength, automatic measuring range selec-
tion is active in all measuring ranges (autorange).
The two current measuring inputs are secured against overload with ceramic high-performance fuses.
The voltage in the measuring circuit may not exceed 600 V.
The multimeter is operated with a common 9 V alkaline battery block. The device may only be operated
with the specified batteries.
The measuring instrument must not be operated when it is open, i.e. with an open battery compartment or
when the battery compartment cover is missing. Measuring in damp rooms or under unfavourable ambient
conditions is not permitted. Unfavourable ambient conditions are:
- Wetness or high air humidity
- Dust and flammable gases, vapours or solvent,
- thunderstorms or similar conditions such as strong electrostatic fields etc.
For safety reasons, only use measuring cables or accessories which are adjusted to the specifications of
the multimeter when measuring.
Any use other than that described above damages the product. Moreover, this is linked to dangers such
as short circuits, fire, electric shock, etc. No part of the product may be modified or rebuilt!
Read the operating instructions carefully and keep them for later reference.
Always observe the safety instructions!
