Temperature coefficient: Direct current 10 ppm R/°C ; Pulsed current < 20 ppm Gauge/°C from 0°C to 18°C and
from 28°C to 50°C.
The above precision is given for a 4-wire connection to the gauge.
You should also take into consideration the actual error of the temperature sensor used. as well as the conditions
of its setup.
Settling time: < 5 ms in "pulsed current" mode.

For negative temperatures. use the value displayed L and not its absolute value.
Temperature coefficient: < 10 % of precision/°C from 0°C to 18°C and from 28°C to 50°C.
The above precision is given for a 4-wire connection to the gauge.
You should also take into consideration the actual error of the temperature sensor used. as well as the conditions of its
setup.
These specifications are given for a measurement current of 0.1 mA to 1mA in direct current mode.
