errors. To ensure the highest possible level of accuracy these D6 sensors are fitted as
standard with an atmospheric pressure sensor; this is always used automatically for atmo-
spheric pressure compensation (PC) - even if the particular channel is not activated. The
atmospheric pressure is programmed by default as a climate variable and can thus be
configured as reference function (s.6.3.6); the measured value can thus also be used to
compensate other sensors.
1.2.Correction of measured values
For the primary measuring channels adjustment values or multi-point adjustment can
be stored in the D7 sensor (either at our factory or via a V7 measuring instrument using
option KL). Correction values (zero-point, gain, base value, factor) are already proces-
sed in the sensor.
1.3.Sensor menu
To ensure the long-term future sustainability of the new ALMEMO
®
V7 measuring
system without having to change the measuring instrument each D7 sensor incorpora-
tes an individual sensor menu which can be downloaded over the serial interface. It is
possible in this way to configure measuring quantities and ranges, the averaging times
for measured value smoothing, or other specific sensor functions. As operating device
either a new ALMEMO
®
V7 measuring instrument or a PC can be used.
1.4.Configuration on PC via USB adapter cable
The ALMEMO
®
D7 sensor can be connected directly to a PC using USB link adapter ca-
ble 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.
To run the sensor menu via the PC the ALMEMO
®
Control software should be used
(from V. 5.14.0.330 up). The 'Sensor menu' is located in the measuring points list under
'Edit'. Here it is possible to program up to 10 measuring points with specific D7 measu-
ring quantities and ranges for the D7 sensor and also other settings. The measuring quan-
tities and ranges are shown at the interface using new clear and informative abbreviati-
ons. Not only the quantity and range are programmed but also automatically the units
(up to six characters) and a comments text; and 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 parameters
or the result of calculations. They can therefore only be programmed and used by the de-
vice itself. The following function channels are available :
