Calibration is typically performed using the HB Tool software connected via a USB cable. A zero calibration is done while the switch is in gas, and a span/max calibration is performed when the switch is covered with oil.
NO (Normally Open) provides no output until liquid is detected (contact closes), while NC (Normally Closed) provides an output until liquid is detected (contact opens). NC is common for fail-safe systems to detect wire breaks.
A flashing green LED indicates the sensor is in operation. A flashing red LED indicates no connection to the mechanical unit. If OFF, there is no supply voltage.
The HB Tool software for configuring sensors can be downloaded from the downloads section on the official HB Products website.
