Value range "Filter":
For noise reduction, the filter level can be adjusted. The filter number determines from how
many measurement values the average value is calculated.
• The setting range is 0x00 to 0x0B

The filter delays the measurement. With a filter number of 0x02, the delay is about 0.2
seconds and with 0x0A about 51.2 seconds.

* 50 ms.
Value range "beta low/beta high":
If 0x02 has been selected at the sensor type parameter "NTC with known B or Beta", the
associated B or Beta [K] should be set here. B or Beta is a four digit number in [K], which can be
found in the NTC sensor data sheet. In order to be stored in the memory bank, the four-digit
number must first be converted to hex format and then stored in the beta low and beta high
bytes.
Example: B or Beta = 4580 which corresponds to Hex 11E4
• Beta low = 0xE4 factory setting
• Beta high = 0x11 factory setting
• The setting range for beta low is 0x00 to 0xFF and for beta high 0x00 to 0xFF.
