Step 1 Temperature Calibration
Requirements: Activate Calibration mode
temperature
Sensor in normal func-
tion (LED green)
Activate Calibration mode 0x06 5000 0x0100
Activate temperature cali-
bration
0x06 5001 0x0103
Start calibration 0x06 5000 0x0101
Wait until Sensor LED gets blue
and FSM status gets 2
0x03 5002 1 2 Integer LED gets
blue
Step 2
Requirements: Calibrate temperature
FSM Status 2 Start calibrate temperature 0x06 5000 0x0103
Measure reference
temperature
Stable readings (poll
until stable)
Check read FSM Status register
until FSM Status gets 7 (takes a
little while)
0x03 5002 1 7 Integer

Notes: Check read FSM Status register
until FSM Status gets 2
0x03 5002 1 2 Integer
Step 3
Requirements: Apply and check Calibration
Calibration succeeded Apply calibration and wait for
FSM Status to get 11
0x06 5000 0x0108
FSM Status 2 Check read FSM Status register
until FSM Status gets 11
0x03 5002 1 11 Integer
Set FSM Status to 2 again 0x06 5000 0x0102
Check read FSM Status register
until FSM Status gets 2
0x03 5002 1 2 Integer
