Mean
ambient
temperature
error in % of scale span, referred to the limit value.
A deviation of the ambient temperature at the switch head and/or the capillary
from the +22 °C calibration ambient temperature produces a shift in the
switching point:
higher ambient temperature = lower switching point
lower ambient temperature = higher switching point
