5.3.15
TA - Pairs of values
Menu -> Settings -> Sensor -> TA Input -> Pairs of values
If pairs of values is selected (see 5.3.12.1), then the values stored here for determining the measured
value are applied as a calibration curve.
Selection:
Configuration
= enter the
quantity
of pairs of values (minimal 2, maximal 30) for
processing and display
Pairs of values
= display and change of the pairs of values.
A pair of values always consists of a velocity value in m/s
and a frequency value in Hz.
The condition being: the pairs of values must be ever
increasing, i.e. the next velocity and frequency value must always
be greater than the previous one.
Example for quantity = 03
01:000.50m/s, 06000Hz
02:010.00m/s, 08350Hz
03:040.00m/s, 12770Hz
If the frequency measured value is greater than in the last pair of values, then the velocity value is
calculated. However, this means that the measurement uncertainty increases as this value is then outside
the calibrated range.
Note:
For switching between different calibration gases each pair of values calibration for the respective
calibration gas can be saved in its own profile (see 5.3.26)
Resetting the factory settings (see 5.3.23) has no impact on the saved profile. Changing the pairs
of values for the various calibration gases can only be reconstructed via the documentation in the Tech-
nical Data Sheet and calibration certificate.
Pt100 input settings for temperature measurement :
5.3.16
Pt100 - Unit
Menu -> Settings -> Sensor -> Pt100 Input -> Unit
The parameter unit to be set here affects the measured value display
Selection:
°C
= display of
temperature
in °C
°F
= display of
temperature
in °F
Analog input settings:
5.3.17
Analog input
Menu -> Settings -> Sensor -> Analog input
Input:
Selection:
4-20mA
=
current input
4-20 mA is selected
0-10V
=
voltage input
0-10 V is selected
Designation:
for each of the two inputs a designation of up to 13 digits for the sensor can
be entered.
Example: pressure sensor
