•
For negative temperatures, use the value displayed (of rdg.) and not its absolute value.
•
Temperature coefficient: < 10 % of accuracy/°C.
•
The above accuracy is given for a 4-wire connection to the temperature sensor.
•
You should also take into consideration the actual error of the temperature sensor used, as
well as the conditions of its setup.
•
Measurement current: 0.65 mA
•
The relative accuracies shown are stated for 360 days and operative conditions from +18°C to
+28°C (+64 °F to +84°F).
•
Typical 90 days relative accuracy can be estimated by dividing the “% of rdg” specifications by
1.8.
•
Typical 2 year relative accuracy can be estimated by multiplying the “% of rdg” specifications
by 1.5.
