(In % from the scale range) referring to the limit value.
Deviation of the ambient temperature at the switching head and/or capillary from the +22 °C calibration ambi-
ent temperature produces a switching head offset.
Higher ambient temperature = lower switching point
Lower ambient temperature = higher switching point
