MW device
Process/laboratory
TMV can be used to control process and laboratory measuring devices and the operating proce-
dure during measurement is distinguished on the basis of the setting made here. If Process is
chosen, TMV is set up for continuous measurement during an ongoing process and if Laboratory
is chosen, it is set up for single measurements in the laboratory.
The pre-defined setting is appropriate for the device in question and must not be changed, since
doing so can stop the system from working.
However, in principle it would be possible to use a laboratory device with a planar sensor for
process measurement using this setting, for example.
Auto start (only for process measurement)
Option activated: The measuring device starts taking measurements automatically after
being switched on.
Option deactivated: After switching the device on, you have to start measuring manually
in TMV by pressing the Start button.
Simulation
You may wish to run the software in simulation mode for presentation purposes. You select this
option here.
Temperature
Product temperature
These settings influence the temperature correction function applied for calibration.
Source: Here, you select whether to measure the temperature of the product and, if so, which
temperature sensor to use. The selection options in the list depend on the individual system
configuration. Temperature measurement can also be deactivated (Source = Off) or given a
predefined value (Source = Fixed).
Port: If one of the analog outputs of a TC MPC card is used for temperature measurement, you
define which of the four outputs is to be used here.
Fixed: If Fixed is selected for Source, you can enter the temperature value to be used in all
cases for measurements here.
Stability: Specify a time span in seconds and a variation range in ºC here. If the measured
temperature does not fluctuate by more than the selected value within the specified period of
time, it is considered to be stable.
Analog: If you are using analog temperature measurement or are measuring the temperature
via the IO-MPC, you define the temperature values that correspond to the input values 0 mA (or
4 mA) and 20 mA here.
Sensor temperature
These settings are required for the temperature correction function for the empty sensor state.
The options correspond to the options for the product temperature.
Analog outputs
In addition to the digital outputs, the process measuring devices have a different number of
analog outputs. The number of analog outputs depends on the configuration level of the device
in question, i.e. the number of installed circuit boards (see Technical data from page 63).
