4.2.3. Display and keypad
The display option allows operation of the testo 6383 transmitter via
the display and four keys.
The LCD display consists of two 7-segment lines for displaying
readings and units and of an information line (for status messages,
for example).
The brightness and contrast of the display and the background
lighting (permanent or off) can be changed via the user menu or the
P2A software.

4.2.5. Relay board (option)
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.

4.2.6. Analog outputs
As analog outputs, the testo 6383 has either
• 1 or optionally 3 current outputs of 0 to 20 mA (4-wire)/4 to
20 mA (4-wire) or
• 1 or optionally 3 voltage outputs of 0 to 1 V/0 to 5 V/0 to 10 V
(4-wire).
The transmitter can be ordered with three analog outputs as an
option.
The optional three channels are galvanically isolated.

4.2.7. Parameters
The following parameters are displayed
• Differential pressure in Pa, hPa, kPa, mbar, bar, mmH2O, inch
H2O, inch HG, kg/cm2, PSI
• Relative humidity in % RH (technical)
• Relative humidity in % WMO* (calculation according to the
WMO standard)
• Degree of humidity in g/kg and gr/lb
• Absolute humidity in g/m³ and gr/ft³
• Water content in ppm (vol) and % vol
• Psychrometer temperature in °Ctw and °Ftw
• Enthalpy in kJ/kg and BTU/lb
• Water vapour partial pressure in hPa and inch H2O
• Dewpoint temperature in °Ctd and °Ftd
• Standardized dewpoint in °CtdA , standardized at atmospheric
pressure (1013 hPa); precondition: Absolute process pressure.
• Dewpoint of H2O2mixture in °Ctm and °Ftm.
* It is possible that condensation appears as of a displayed
humidity starting from 70 % and is shown on the display. This
unit is used in meteorology, amongst others. When calculating
the relative humidity the Magnus coefficient with undercooled
water is used in accordance with WMO.
Calculated humidity variables correspond to the medium of
air. With other gases/gas compositions, deviations may
occur, e.g. with the enthalpy.
• Temperature °C and °F

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
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 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 53
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.
