Scaling - TESTO 6381 Instruction Manual

4.2.8.

Scaling

There are three types of min./max. values:
1 The measuring range: The maximum sensor performance is in
this range. Values outside of the measuring range are displayed
via messages, for example. Measuring range, see table
(below).
2 Standard scaling: The output signals are assigned to this
measuring range as standard:

◦
Measuring range, see table (below).
3 The maximum settings for the manual scaling

With the alarm definition, however, the physical measuring
range limits are decisive.

0 to 1000 hPa
during delivery if no entries are made in the order code
after exchanging the unit, the measuring range recorded in
the instrument is applied as standard.
The transmitter even retains its scaling with the voltage
disconnected.
The maximum limits can be calculated as follows:
X = difference between MIN. and MAX. value of the
standard scaling
(Max. value of standard) + (50 % of X)
(Min. value of standard) - (50 % of X)
It is thus possible to scale beyond the measuring range, e.g.
for the adjustment of the scaling limits to standard values of
a PLC.
