Chauvin Arnoux Metrix MTX 3293B User manual

Quick Start Guide
MTX 3292B / 3293B, ASYC IV
Portable 100,000 cts Graphic Multimeter
This guide is available in various laguages on the CD
supplied with the instrument.
We thank you for your confidence in the quality of your products.
A complete user’s manual is also provided on the CD supplied
with the instrument.
It can be download from : www.chauvin-arnoux.com.
Attention : for your safety and to protect your property,
please read carefully the safety datasheet enclosed with
your instrument.
This multimeter complies with the EN 61010-2-033 CAT IV
600 V – CAT III 1000 V, safety standard on double insulation for
electronic measuring instruments. IP 67 as per standard
IEC 60529. Then, if the instrument is immersed, it must be dried,
in particular the terminal block, before it can be used again.
This instrument has been designed for use indoors :
- in an environment with pollution level 2,
- at an altitude of less than 2000 m,
- at a temperature between 0°C and 50°C,
- with relative humidity < 80 % up to 35 °C.
It can be used for measurements on the circuits of :
- Category III installations for voltages up to 1,000 V
(AC or DC) relative to earth.
- Category IV installations for voltages up to 600 V
(AC or DC) relative to earth.
For safety reasons, only use suitable cords supplied with the
instrument: they comply with the EN 61010-031 standard.
Before each use, make sure that they are in perfect condition.
When the instrument is connected to the measuring circuits,
never touch a terminal which is not in use. Use only suitable
accessories delivered with the instrument or approved by the
manufacturer.
If the measurement category of the accessory is different from
that of the instrument, the lowest category applies to the unit.
