Ambient temperature
influence referring to
the control range / limit value
range When the ambient temperature on the switching head deviates from the calibration
ambient temperature of +22 °C, a switching point offset occurs.
Higher ambient temperatures = lower switching point
Lower ambient temperature = higher switching point
