10.4. Connection to the Sensor Unit: “SENSOR” Connector
The table below gives the pin assignment in the connection with the sensor unit. In the
connection with the sensor unit, it is recommended to connect all of the following pins.
* Connector for connection “SENSOR”: D-sub 15 pin connector male, M2.6mm screw
* Connector for connection “SC1” : D-sub15 pin connector female, M2.6mm screw
“SENSOR” Description Details Sensor unit

The (V-E) calculated value may become 0.1 or lower due to errors in the sensor's output voltage
and errors with the measuring instrument. If it falls below 0.1 in this manner, we recommend
rounding up to 0.1 and calculating.
