8.1 Heating (ISDU index 4102)
To ensure good temperature stability over the whole temperature range, the
measuring cell is regulated to a constant temperature. The regulation of the
heating is activated by the factory and can be deactivated by writing the value 0 to
the parameter of the heating (ISDU index 4102).
This has the following effects
●
Reduction of temperature stability
●
Current consumption decreases when operating
●
Accuracies deviate from the indications in the data sheet
8.2 Measuring method (ISDU index 4106)
The required measuring method is set to the inclination or vibration measurement
via the ISDU index 4106.
8.3 Measuring cell and ambient temperature, heating power (ISDU index
4110...4112)
Measuring cell and ambient temperature inside the housing are redetermined
every 200 ms. They can be read via ISDU access (in any device status). The
signed 16-bit values (two's complement) indicate the temperature in 1/10 °C.
