4.1.1. Functions and use
The testo 6381 transmitter with Ethernet module is used together
with the plug-in, adjusted probes from the testo 6610 family.
Please refer to volume 2, testo 6610 probes, page 90 for
information about commissioning, operating and maintaining the
testo 6610 probe.
The testo 6381 transmitter is suitable for the following applications
with Ethernet networking, amongst others:
• Clean rooms
• Test benches
• Drying processes
• Filling processes
• Painting systems
• Monitoring flow velocities or volumetric flow rates in air
conditioning systems
In addition to the signal transmission of the readings to a control
unit via analog outputs, the measurement data can simultaneously
be recorded, documented and visualized via Ethernet.
Furthermore, it is possible to issue an alarm for those responsible

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:
◦ during delivery if no entries are made in the order code
◦ after exchanging the unit, the measuring range recorded in
Pos: 36 /TD/Produktbeschreibung/Übersicht/ MUF 63xx/Tabelle Skalier ung MUF 638x @ 3\mod_1236343950 039_79.doc @ 27502 @
the instrument is applied as standard.
The transmitter even retains its scaling with the voltage
disconnected.
Measuring range, see table (below).
3 The maximum settings for the manual scaling
◦ 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.
With the alarm definition, however, the physical measuring
range limits are decisive.

4.2.9. Alarm handling
For upper and lower alarm limits, individual alarms as well as
collective alarms can be specified. If the collective alarm function is
activated, an alarm is triggered as soon as the alarm limit of an
alarm is exceeded, if this alarm is assigned to the collective alarm.
The testo 6381 monitors limit values with the help of relays. If a
reading is outside the limit values, a relay to be specified by the
user is switched.
If the reading reverts to more than a specified hysteresis below or
above the limit value, the alarm is cancelled.
In addition, information about the occurrence of error/status
messages can be provided by means of a collective alarm relay,
Pos: 39 /TD/Überschriften/MUF/1.3/2.3 Inbetri ebnahme @ 3\mod_123425880576 8_79.doc @ 24027 @ 2
see Status, warning and error messages, page 81
If multiple alarm messages are activated at the same time,
the last alarm is shown. If the alarm is cancelled again, the
previous messages are no longer shown.
