11.5 Temperature Calibration
11.5.1 Internal Temperature Sensor Calibration
1. Apply a known temperature in 0.1°C, and ensure that temperature Temp
TINT
is applied to the device.
2. Read the TINT offset
old
from Internal Temp Offset.
3. Read the reported temperature from DAStatus2():
• TINT = AAaa of DAStatus2()
Is TINT > 0? If yes, TINT = AAaa – 2732.
4. Calculate temperature offset:
= - +
TINT
old
TINT offset TEMP TINT TINT offset
5. Write the new Internal Temp Offset value to data flash.
6. Recheck the DAStatus2() reading. If the reading is not accurate, repeat the steps.
11.5.2 TS1 Calibration
1. Apply a known temperature in 0.1°C, and ensure that temperature TEMP
TSx
is applied to the thermistor
connected to the TSx terminal. "TSx" refers to TS1.
2. Read the TSx offset
old
from External × Temp Offset, where × is 1.
3. Read the appropriate temperature from the DAStatus2() block as TSx.
4. Calculate the temperature offset:
= - +
TS x
old
TSx offset TEMP TSx TSx offset
where × is 1.
5. Write the new External × Temp Offset (where × is 1) value to data flash.
6. Recheck the DAStatus2() reading. If the reading is not accurate, repeat the steps.
