Whichever value is greater. The instrument must be at a constant
ambient temperature for a minimum of 15 minutes.
A correct temperature measurement is impossible if the
temperature of the object is more than 85 °C below the sensor head
temperature (temperature reading is too high, no error message)
Repeatability:
0.5% of measured value °C or 0.5 °C
whichever value is greater, ambient temperature is constant
