1Measuring uncertainty in accordance with GUM: ±0.5 % of measuring range
final value ±0.3 Pa.
The determination of measurement uncertainty takes place according to GUM (Guide to the Expression
of Uncertainty in Measurement):For the determination of measurement uncertainty, the accuracy of the
measuring instrument (hysteresis, linearity, reproduceability), the uncertainty contribution of the test site
as well as the uncertainty of the adjustment site (works calibration are taken into account. For this
purpose, the value of k=2 of the extension factor, which is usual in measurement technology is used as
a basis, which corresponds to a trust level of 95%.
2Minor mixtures of the media may occur at the positive and negative pressure
side due to the automatic zeroing cycle.

This has a floating switch capacity of 250 V AC/3 A. The switching
limits and hysteresis as well as the function as relay for the
collective alarm can be set via the display or the P2A software.
Further features include:
• Function of changeover contacts (NC/NO contacts) freely
selectable
• 12 terminals for a total of 4 relays.
If no relays are available, settings for monitoring limit values
or alarms can still be controlled via the display. The alarm
status will be shown on the display.
Only have the transmitter wired and connected by
authorized personnel with the voltage disconnected.

4.2.7. Scaling
There are three types of min./max. values:
1The 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).
2Standard 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
the instrument is applied as standard.
The transmitter even retains its scaling with the voltage
disconnected.
Measuring range, see table (below).

4 Transmitter
15
3The 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.

4.2.8. 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 6383 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,
see Status, warning and error messages, page 39

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.

Requirement for the connecting cable of the supply:
• Shielded and insulated with cross-section of at least
0.25 mm², maximum 1.5 mm² without wire end sleeves.
• The supply line must be secured against exceeding
0.5 A.
• An OFF switch must be installed in an easily accessible
position close by and be marked as such.
1. Disconnect terminal strip for voltage supply and analog outputs.
2. Strip the cable ends, clamp wire end ferrules on and screw
down with voltage terminals/channel terminals.

3. Tie together each of the two adjacent cores using a cable tie.
4. Attach terminal strip for voltage supply and analog outputs.

4.3.2.3. Connecting the relay outputs
Only have the transmitter wired and connected by
authorized personnel with the voltage disconnected.

terminals
There is the option of twelve terminals for a total of four relays.
1. Remove relay cover.
2. Disconnect relay terminal strip.
3. Strip cable ends and clamp on wire end ferrules.
4. Connect relays according to chosen function (NC/NO) (see
diagrams below; relay 1 is shown as an example of a
connection).
Connection note
• For the connection, a double-insulated mains cable
(sheathed cable) with a cross-section of at least 1.5
mm² must be used.
• Cable connection (2) may not be routed in a loop within
the relay trough (1).
• It is recommended that you always tie 2 adjacent cores
to one another using a cable tie (3).

• The insulation of the cable must be fed at least 5 mm
(4) into the relay tray up to the elevated part.
Use of relay as NC contact (NC = normally closed)
1Alarm/status light
(example of installation)
2250 V AC/DC, 3 A
The busy light (alarm/status light) is permanently on until
the relay opens or the circuit is interrupted. This circuit can
therefore be used to monitor the functionality of the alarm
circuit, as a cable break, for instance, is indicated by the
busy light going off.
