Average
ambient tem-
perature
influence
(in % from the scale range) referring to the limit value.
When the ambient temperature on the switch head and / or the capillary devi-
ates from the calibration ambient temperature +22 °C, a switching point offset
occurs.
Higher ambient temperature = lower switching point
Lower ambient temperature = higher switching point
