6 Bases for measurement
6.1 Special functions
Zero point shift
A zero point shift can be made for each of the two temperature channels T1 (only
TFS0100) and T2.
Formula
Displayed temperature = measured temperature - zero point shift
Standard setting is off. That means 0.0° and that a zero point shift cannot take place.
The zero point shift is used primarily to compensate for sensor deviations. If a different
value than off is adjusted, it is displayed briefly when the device is switched on and in-
dicated by the Corr arrow in the display during operation.
Display correction factor
This factor only has an effect on the Typ-K input T2.
Formula
[°C]:
Displayed temperature = measured temperature * Corr
[°F]:
Displayed temperature = (measured temperature - 32 °F) * Corr + 32 °F
Standard setting is off = 1.000
This factor is provided to compensate for thermal transition losses in surface measure-
ments. These occur when very high temperatures of objects should be measured, the
surface of which is cooled down by the cooler environment. Similar effects can also
occur with sensors with a greater mass. If a different value than off is adjusted, it is
displayed briefly when the device is switched on and indicated by the Corr arrow in the
display during operation.
Base address
Multiple products can be queried simultaneously via an interface using the GRS3105
interface converter. For this purpose, it is prerequisite that all products have a different
base address. If multiple products are connected together via an interface, the base
addresses must be configured accordingly.
Channel 1 of the product is addressed via the adjusted base address. Channels 2 to 6
have the following addresses.
Example
Base address 21 + Channel 1 = 21
+ Channel 2 = 22
etc.
6.2 Measurements with the TFS 0100E combination
measuring probe
The TFS 0100 is specially developed for room climate measurement. TFS 0100
probes are not interchangeable without recalibration. It includes a sensor for measure-
ment of relative air humidity and a sensor for measurement of environmental temper-
ature T1.
6.2.1 Relative air humidity r.H.
Air humidity measured in the probe tip with 0.1% resolution.
