Thermal effects with reference to the set
span
TD = nominal value/set span
for -10 °C … +60 °C (+14 °F … +140 °F):
±(0.2 % x TD + 0.2 %)
for -40 °C … -10 °C (-40 °F … +14 °F);
+60 °C … +85 °C (+140 °F … +185 °F): ± (0.4 % x TD + 0.4 %)
Temperature coefficient (maximum TK)
(But not exceeding the error due to thermal
effects.)
for zero signal and span:
for -10 °C … +60 °C (+14 °F … +140 °F): ±0.08 % of nominal
value/10 K
for -40 °C … -10 °C (-40 °F … +14 °F); +60 °C … +85 °C
(+140 °F … +185 °F): ±0.1 % of nominal value/10 K
