- Construction
A typical measuring system consists of:
§ MAC
100 multiparameter signal converter
§ 1
(or up to 2) sensors of the OPTISENS series
§ Sensor
cable
§ MAA
mounting assemblies
- Option
The device is available as a one channel (one signal input) or a two channel
version (two signal inputs). You can connect one sensor to the one channel
version and up to two sensors to the two channel version.
- Sensors
For further information refer to the
manual of the relevant sensor.
- Also
note the table with the sensor input combinations on page 7.
Display
and User interface:

ambient temperatures below -25°C / -13°F" may affect the readability of
the display!
- Operating
elements: 4 push buttons for operator control of the signal converter without
opening the housing.

menu:
§ The
operation menu consists of the measuring mode and the menu mode:
§ Measuring
mode: 4 pages (first and second measuring page with measuring results, status
message and trend diagram).
§ Menu
mode: variety of main and submenus that allow to customise the device according
to the demands of the measuring point.

Note:
the manufacturer strongly recommends to protect the signal converter from
external heat sources such as direct sunlight as higher temperatures reduce the
life cycle of all electronic components.
