Readings in % refer to the measuring span
For a correct determination of the overall measuring deviation, 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) ±0.2 % for measuring ranges with a lower limit less than 0 °C (32 °F)
3) Use resistance thermometers with shielded cable and ground the shield at at least one end
of the lead if the lines are longer than 30 m or leave the building. Operate the instrument in a
grounded state.
4) During transient interferences (e.g. burst, surge, ESD) take into account an increased
measuring deviation of up to 2 %.
