Readings in % refer to the measuring span
For a correct determination of the overall measuring error, both sensor and transmitter
measuring deviations have to be considered.
1) The temperature transmitter should therefore be protected from temperatures over 85 °C (185 °F).
2) For measuring spans smaller than 50 K additional 0.1 K
3) ±0.2 % for measuring ranges with a lower limit less than 0 °C
4) Use resistance thermometers with shielded cable, and ground the shield on at least one end of the lead, if the
cables are longer than 30 m or leave the building.
