(1): only for internal temperature measurement.
(2): Depending on sampling rate : given for 1 measure / 2mn .
(3): average value for standard lighting when temperature is above 0°C.

±
2°C. Drift: 0,01%/°C max in voltage and 0,05°C/°C typical in temperature measurement.
Except for the 1522-K, drift 0,02°C/°C max in temperature measurement and for the 1550-K1, drift 0,05°C/°C max +
100ppm/°C of the read value in temperature external measurement on Text1 Text2 Text3 et Text4.
(5): At temperature 23 °C ± 2 °C, accuracy 3% from 10 to 90%HR, 5% outside, drift 0.15% per °C typical.
(6): Drift maximum, except precision of probe PT100 according to the temperature of the datalogger.
Type 1511PT: 150ppm/°C of the gauge is maximum 0.03°C/°C
Type 1511PT1: 100ppm/°C of the gauge is maximum 0.1°C/°C
the compensation of the resistance of wire is ensured by the wiring 3 wires, precision given up to 10 Ohms per wire.
(approximately 120m of 0,25mm2 or 250m of 0,5mm2.pour of the wire of good quality).
Correction of zero of the PT100.
The zero of the PT100 can be adjusted precisely with the software of management of the dataloggers
(Coefficient safeguarded in Datalogger).
The variation can go from -10°C to +10°C is -18°F à+18°F.
