1. Brief description / 2. Assembly

1. Brief description

The panel instrument M1-1U is a 4-digit device for measuring of different kind of measuring signals such as
direct voltage/direct current, temperature and frequency and a visual limit value monitoring via the display.
The configuration happens via three front keys or via the optional PC-software PM-TOOL. An integrated
programming interlock prevents unrequested changes of the parameter and can be released again via an
individual code. The electrical connection happens on the rear side via plug-in terminals.
Selectable functions like e.g. the recall of the min/max-value, Tara-function, averaging, a direct change of
the limit value in operating mode and additional measuring support points for linearisation complete the
concept of a modern device.

2. Assembly

Please read the Safety instructions on page 23 before installation and keep this user manual for future reference.

1. After removing the fixing elements, insert the device.

2. Check the seal to make sure it fits securely.

3. Click the fixing elements back into place and tighten the clamping screws by hand. Then use a
screwdriver to tighten them another half a turn.

CAUTION! The torque should not exceed 0.1 Nm!
