1. ALMEMO® D6 digital sensors
ALMEMO® D6 digital sensors incorporate not only an I2 interface integrated in the
plug but also a second serial interface. Each such sensor can thus be connected to any
ALMEMO® device with the 'DIGI' setting; (from V5 up an update may be required).
It will thus be possible to configure and use new functions and quantities not actually
supported by your ALMEMO® devices; this is achieved by means of the ALMEMO®
ontrol software and a sensor menu stored in the sensor itself. For measured values
all functions for correction, spot adjustment, and multi-point adjustment are available
as in previous versions. (see 2.2) A new function is the possibility of programming an
internal measured value smoothing factor over multiple channels, (see 3.3).
2. Operation as sensor on any ALMEMO® instrument
The ALMEMO® D6 sensor, using measuring range ´DIGI´, supplies digital measured
values from up to 4 measuring channels to the ALMEMO® device, where these are
then processed as usual. Any channel can be switched off, deactivated, and reacti-
vated via the ALMEMO® device itself; and concealed channels (marked with ~) can
be managed in exactly the same way. ertain function channels can also be pro-
grammed and used. The sensor is powered via the measuring instrument. To operate
certain sensors in sleep mode it will be necessary to program a sleep extension.
The operating radius of these sensors when connected to a measuring instrument can
be extended by means of universal extension cables ZA9090-VK xx; measured val-
ues and connector programming can then be transmitted interference-free in serial
form via an RS485 driver.
When configuring the sensor menu, given the absence of drivers for the second inter-
face, the extension must be no more than 10 meters in length. When using the exten-
sion cable sleep mode operation is not possible.

2.1 Atmosp eric pressure measurement and compensation
Some measurable variables (those in the measuring range list marked 'with P ') are af-
fected by atmospheric pressure; failure to take account of this may lead to substantial er-
rors. To ensure the highest possible level of accuracy these D6 sensors are fitted as stan-
dard with an atmospheric pressure sensor; this is always used automatically for atmo-
spheric pressure compensation (P ) - even if the channel concerned is not activated.
Atmospheric pressure is programmed by default as a climate variable; it can thus be con-
figured as a reference function and the measured value can be used to also compensate
other sensors.
2.2 Correction of measured values
For the primary measuring channels it s possible in the D6 sensor to store values not
only for spot adjustment but also for multi-point adjustment; (the device must have
option KL). On completion of calibration the measuring accuracy will thus be deter-
mined no longer by the measuring instrument but exclusively by the sensor itself.
2.3 Sensor menu
Each D6 sensor has a stored individual sensor menu; this can be downloaded via the
serial interface; it is used to configure measuring quantities and ranges, an averaging
period for measured value smoothing, or other specific sensor functions. As operating
device either a P or a new ALMEMO® V7 measuring instrument can be used.
3. Configuration on PC via USB adapter cable
The ALMEMO® D6 sensor can be connected directly to a P using USB adapter cable
ZA1919-AKUV at a baud rate of 115.2 kilobaud. A microcontroller incorporated in the
adapter cable automatically sets the power supply, baud rate, and device address that the
sensor requires.
onnecting a D6 sensor directly to the P is performed primarily for the purpose of sen-
sor configuration.
Each such sensor can be configured in various ways, depending on its operating mode,
i.e. connected to an ALMEMO® measuring instrument or directly to a P via the USB
adapter cable. (See the following table):

** with device option KL
3.1 Using t e sensor menu
To access and use the sensor menu the ALMEMO® ontrol software should be used
(from V. 5.14.0.330 up). 'Sensor menu' is located in the measuring points list under
'Edit'. Here the four measuring points can be programmed with the special D6 mea -
suring ranges for the D6 sensor and other settings. At the interface the available mea-
suring ranges appear with new easy-to-understand abbreviations, while on the measur-
ing instrument itself only the 'DIGI' range can be used. Not only the range is pro -
grammed but also automatically the units (2 characters) and a comments text; the
channel is then locked at level 5. Ranges can be deleted by selecting '- - - -' in the list.
Function channels * are determined in the measuring instrument - either as parame-
ters or the result of calculations. They can therefore only be programmed and used by
the device itself. The following function channels are available :
Batt, Mess, Alrm, Diff, Max, Min, M(t), n(t), M(n), Flow, Time
However, if connected directly to the P , these are not available. The advisory note '!
unusable' will be displayed in the comments text.
Further parameters, depending on sensor type, can be set (e.g. temperature / atmo-
spheric pressure compensation).
Once configuration has been completed the D6 sensor can be connected to any
ALMEMO® measuring instrument.
- 7 -

3.2 Atmosp eric pressure compensation
If the sensor incorporates an atmospheric pressure sensor atmospheric pressure com-
pensation is set by default to ´Sensor´; i.e. in the sensor menu the current measured
value is displayed under ´Value´. However, if a particular value needs to be used (e.g.
altitude above sea level, weather forecast, channel), this value can be programmed in
menu item ´value´. It is also possible, by simply clicking on the ´Reference´ option
here, to use the measured value ´Atmospheric pressure´ to compensate other sensors
connected to the same ALMEMO® device. This programs abbreviation ´*P´ in the
designation of measuring channel ´D AP´ thus ensuring that this measured value is al -
ways available in the ALMEMO® device for the purpose of atmospheric pressure
compensation.(see Manual, 6.3.6).
3.3 Averaging period (smoot ing)
All measured values on the primary channels are internally scanned all the time at the
individual refresh rate. (see 12.4) If measuring conditions make these values too un-
stable an averaging period can be entered in the menu automatically for both primary
channels; measured values will then be smoothed by a sliding average.

6. D6 temperature / umidity sensor FHAD46
The FHAD46 comprises a fully adjusted digital capacitive sensor which can be exchanged
at any time without any loss in accuracy. For automatic pressure compensation, an air
pressure sensor is installed. The humidity quantities are calculated from the real measur-
able variables - temperature, relative humidity, atmospheric pressure - on the basis of for-
mulae as per Dr. Sonntag and the enhancement factor as per W. Bögel (correction factor
´fw(t,p)´ for real mixed gas systems). The measuring range and accuracy of this system
are thus much greater than with earlier sensors. The measured atmospheric pressure can
also be used in the ALMEMO
®
measuring instrument as reference atmospheric pressure.

7. D6 temperature / umidity sensor FHAD46C
D6 temperature / humidity sensors FHAD46 are based on the fully adjusted Multi-
sensor module FH0D46- x; this comprises a capacitive temperature / humidity sensor,
a barometric atmospheric pressure sensor, and an EEPROM. (see Figure 7-1) This
means that the Multi-sensor module can be replaced or adjusted quickly and easily
without any loss in accuracy. The Multi-sensor module incorporates a unique serial
number designed to exclude any risk of incorrect replacement; this serial number can
be displayed via the sensor menu. (see Figure 7-1) The barometric atmospheric pres-
sure sensor is used to determine atmospheric pressure directly at the measuring loca-
tion. On this basis atmospheric pressure compensation can then be performed
automatically in the ALMEMO® connector. Information stored in the integrated EEP-
ROM ensures that the Multi-sensor module can be adjusted quickly and easily. The
humidity variables are calculated from the real measurable variables - temperature,
relative humidity, atmospheric pressure - on the basis of formulae as per Dr. Sonntag
and the enhancement factor as per W. Bögel (correction factor 'fw(t,p)' for real mixed
gas systems). The measuring range and accuracy of this system are thus much greater
than with earlier sensors. The measured atmospheric pressure can also be used in the
ALMEMO® measuring instrument as reference atmospheric pressure (see 3.2).

8. D6 temperature / umidity sensor FHAD467
Humidity sensor FHAD467 is much the same as type FHAD46 (see 7.) - with the ex-
ception that it is specially designed for use in compressed air pipes up to 16 bar. In
cases involving a pressure-dependent variable pressure compensation can be per-
formed by specifying the appropriate atmospheric pressure up to 16 bar. This amount
can also be displayed as a channel with range ´D p´. (see Table 8.2.1 ´with P ´)

3. Dew point DT, tdB-03 DIGI -1 °C 0.1 K
The new D6 humidity ranges can be partly configured on the device itself; however, the
appropriate ALMEMO® standard ranges ´H DT´, ´H AH´, H VP´, ´H En´ must have
been programmed accordingly. ´DIGI´ will replace these ranges automatically with the
new ones..
Please note that new ranges ´D dv´ or ´D p´ may be lost in this process.
They can then only be restored via the P .

9. D6 temperature / umidity sensor FHAD46C7
Humidity sensor FHAD46 7 is much the same as type FHAD46 . (see chapter 7)
However, it is specially designed for use in compressed air pipes up to 16 bar. In
cases involving a pressure-dependent variable pressure compensation can be per-
formed by specifying the appropriate atmospheric pressure up to 16 bar. (see Table
9.2.1 'with P ') This amount can also be displayed as a channel with range 'D p'.

3. Dewpoint DT, tdB-03 DIGI -1 °C 0.1 K
Providing the appropriate ALMEMO® standard quantities 'H DT', 'H AH', 'H VP', 'H En'
have been programmed accordingly, the D6 humidity ranges can be configured partly on
the device itself. 'DIGI' will substitute these ranges automatically with the new ones.
Please note that in this process new ranges 'D dv' or 'D p' may be lost.
They can then only be restored via the P .
