Intended Use; Safety Instructions - VOLTCRAFT CM-100 Notice D'emploi

Intended Use

The CM-100 is a portable measuring device for ascertaining the carbon dioxide concentration (CO
the surrounding air using the exact and long-term stable NDIR measurement method (Non-Dispersive-
Infrared-Absorption measurement). In addition the air temperature can be measured. Both measured
values are shown in the display at the same time. The measurement interval is 2 minutes. This provides
constantly current values. Threshold values can be individually adjusted by the user. An alarm is sound-
ed when these threshold values are exceeded. The external sensor is compensated for altitude and
temperature, so that the measured values are still exact at different altitudes and temperatures. The
temperature compensation is carried out automatically, the operational altitude must be manually adjust-
ed.
An RS-232 interface allows the further processing of the measuring data with an optional data cable.
The device is powered with 6 micro-batteries (type AAA, UM4). Operation with a power pack unit is also
possible. Batteries and plug-in power pack are not included in delivery.
Measurements must not be carried out under unfavourable ambient conditions.
Adverse ambient conditions include:
- Excessive dampness or humidity
- Dust and combustible gases, vapours or solvents Use other than that described above will lead to dam-
age to the product.
No part of the product must be modified or rebuilt!
The safety instructions must be observed!
