1. Application
The METRALINE EXM25 is an intrinsically safe multi-
meter which can be used in areas with a potentio-
nally explosive atmosphere in accordance with ATEX
(EN 60079-0 and EN 60079-11) and EN/IEC 61010
for voltage, resistance, current, frequency measure-
ments with measurement accessories for
measurement of temperature and high current.
Model M210A with rechargeable battery and model
M210B with Lithium battery.
1.1 Intended use
This device is intended for use in applications as
described in the operating instructions only.
Thus, it is imperative to observe the notes on safety
and the technical data in conjunction with the
ambient conditions.
Any other form of usage is not permitted and can
lead to accidents or destruction of the unit.
Any misuse will result in the expiry of all guarantee
and warrantly claims.
2. Safety Precautions
When used for its intended purpose, safety of the
operator, as well as that of the instrument, is assured.
The voltage measurement tips contain moulded
multipliers within both test prods. They are extreme-
ly safe and comply with overvoltage category CAT IV.
In order to maintain awless technical safety condi-
tions, and to assure safe use, it is imperative that you
read these operating instructions thoroughly and
carefully before placing your instrument into service,
and that you follow all instructions contained
therein.
The device may only be used in the designated
Ex zones (see section 5.1) and inside of the safety-
related limit values (see section 5.2).
Before starting resistance measurements make
sure that the test object is at zero-potential.
Perform voltage measurements most up to the
following limits:
With probes EXM 72010 up to 1000 V
Faultless indication of display values is only
guaranteed between -10°C ... +40°C.
Hold the instrument by its handgears only, to
avoid covering the display or touching the test
electrodes.
