Insert the different BNC connect of the sensor in the 3 holes, following this sequence : pH, O2, Conductivity. .. figure:: Image/Physico_Chemical/Hardware/BNC_inbox.JPG :width: 646px :align: center :height: 771px :alt: alternate text :figclass: align-center #. Fix all the BNC connector with a seal and a nut. .. figure:: Image/Physico_Chemical/Hardware/BNC_inbox_fixing.JPG :width: 629px :align: center :height: 758px :alt: alternate text :figclass: align-center #. Cut 12 cm of **red wire diameter 3 mm**. use a **stripped clamp** for 1 cm of both side of the wires. .. figure:: Image/Flowmeter/Hardware/red_wire_stripped.JPG :width: 816px :align: center :height: 778px :alt: alternate text :figclass: align-center #. Cut 12 cm of **black wire diameter 3 mm**. use a **stripped clamp** for 1 cm of both side of the wires. .. figure:: Image/Flowmeter/Hardware/Black_wire_stripped.JPG :width: 867px :align: center :height: 827px :alt: alternate text :figclass: align-center #. Take **1 crimp lug**. use a **crimping tool** to set one pod on **red wire diameter 3 mm**. .. figure:: Image/Flowmeter/Hardware/red_wire_pod.JPG :width: 792px :align: center :height: 682px :alt: alternate text :figclass: align-center #.

Set the red banana connect inside his hole. Then, connect the red wire on the red banana connector with the pod side, then screw the nut after. Do the same for the black banana connect (Ground). .. figure:: Image/Physico_Chemical/Hardware/banana_plug-on-box.JPG :width: 849px :align: center :height: 668px :alt: alternate text :figclass: align-center #. Connect the otherside of the **red wire diameter 3 mm** from the banana connect and the red wire wire from the **voltage divider** in the **Vin outlet of the MKR CARRIER**. Then connect the black wire from the banana connect and the black wire from the **voltage divider** in the **GND outlet of the MKR CARRIER**. .. figure:: Image/Flowmeter/Hardware/input_Wire.JPG :width: 824px :align: center :height: 674px :alt: alternate text :figclass: align-center #. Set the "**push button**" inside his hole, and use a nut to make sure it didn't move. .. figure:: Image/Physico_Chemical/Hardware/push-button-inbox.JPG :width: 884px :align: center :height: 701px :alt: alternate text :figclass: align-center #. Connect both wire of the "** push button**" on the Grove board (one of the wire need to be connect to the VCC port and the other to the D2 port), then screw it. The wire connection place is not important. .. figure:: Image/Physico_Chemical/Hardware/push-button-connect.JPG :width: 871px :align: center :height: 763px :alt: alternate text :figclass: align-center #. Set a cable gland on the both hole remaining. One is for the **ORP sensor wire**, and the other one is for the **temperature sensor**. .. figure:: Image/Physico_Chemical/Hardware/stuffing-box.JPG :width: 437px :align: center :height: 729px :alt: alternate text :figclass: align-center #. Set the "**ORP sensor**" wire inside the cable gland (from outside to inside the box), then, screw them on the screw terminal block. ** caution: the blue and red cables must not touch each other as this could damage the sensor.** .. figure:: Image/Physico_Chemical/Hardware/ORP_sensor_screw.JPG :width: 900px :align: center :height: 648px :alt: alternate text :figclass: align-center #. Set the "**Temperature sensor**" inside the cable gland (from inside to outside the box). Then, connect the other different sensor on the BNC. .. figure:: Image/Physico_Chemical/Hardware/sensor_plug.JPG :width: 900px :align: center :height: 758px :alt: alternate text :figclass: align-center #. Close the box. The Physico-chemical datalogger is ready to be use. **Please be careful, the datalogger need to be powered by a 12V direct current, use an adapted power supply**. .. figure:: Image/Physico_Chemical/Hardware/box_close.JPG :width: 900px :align: center :height: 520px :alt: alternate text :figclass: align-center
