Temperature Output CalculationsTo calculate Temperature by measuring the current or voltage outputuse the following formulas.For Current output in ºC (0 to 100ºC)ºC = (Output measured in miliamps – 4) ÷ 0.16 = ºCEXAMPLE: (8.0 mA – 4) ÷ 0.16 = 25ºCFor Current output ºF (32 to 212ºF)ºF = (Output measured in miliamps – 4) ÷ 0.08888 +32 = ºFEXAMPLE: (8.0 mA – 4) ÷ 0 .08888 +32 = 77ºFFor Voltage output in ºC (0 to 100ºC)ºC = (Output measured in volts ÷ 0.10) = ºCEXAMPLE: (0.25 Vdc ÷ 0.10) = 25ºCFor Voltage output ºF (32 to 212ºF)ºF = (Output measured in volts ÷ 0.005555) +32 = ºFEXAMPLE: (0.25 Vdc ÷ 0.005555) +32 = 77ºF10. CalibrationYour transmitter has been factory calibrated to meet or exceed thespecifications outlined in this manual. To maintain originalspecifications it is generally recommended that your transmitter berecalibrated on an annual basis depending on operating conditions.6
