Register Range Register description
01h -4000 ÷ +8500
The temperature measured with a resolution given to 2 decimal places
(in the U2 code, excluding decimal point, for example, the value of
3523 means the temperature of 35.23°C)
02h
00h, 10h,
20h,40h, 80h
Status of the temperature contains the error code which must be
interpreted as follows:
00h - measuring correctly
10h - flooding the interior of the sensor
20h - damage temperature sensor
40h - measured temperature is lower -40°C
80h - measured temperature is upper 85°C
03h 0÷2
Specify the decimal point as a result, the value of 2 means that a point
precedes the last 2 digits, the value of 0 means no decimal point
