This product deals with ultrasonic signals in a differential manner. Therefore, probe wiring must include "Signal ㊉", "Signal ㊀" and "Ground Isolation ". Use 2-core cable (2C) with a grid structure, outside diameter (OD) of less than 7 millimeters, conductor cross-section of 0.5-0.75 mm2 , with a total length of less than 10 meters, so as to avoid signal attenuation caused by poor measurement quality. In addition, the upstream and downstream probe wire length must be consistent to avoid transmission error. The wiring method is as shown below:
After removing the cover, Erminals can be seen inside: "Signal ㊉", "Signal ㊀" and "Ground Isolation " . Secure the wires through the waterproof packing head to the corresponding terminals in the sequence shown below.
Before replacing the cover, it may be advisable to reinforce the waterproof features of the cover by screwing, gluing, etc., as shown by the dotted line on the figure below-left. After covering, screw the cover on tightly to complete the probe wiring procedure.

1.The quality of the wiring will affect ultrasound signal quality and measurement accuracy. It is important to install the wiring correctly and securely.
2.After cutting the length of wire required, first pass one side of the head through the waterproof packing head of the probe and then peel off the 40-millimeter insulation layers on both sides. Finish the insulation layer as shown in the figure below.
3.Separate the jacket with a corresponding 35-millimeter heat shrink sleeve and a 20-millimeter heat shrink sleeve on the outer circumference of the cable. Heat to fasten, then clip the Y-shaped terminal.
4.Secure each terminal of the probe in the correct position, as shown in the following figure. Tighten and fix the wires, then glue the probe cover shut as described in the previous section. (If there is further need for waterproofing, waterproof resins or rubbers can be used to fill in the space.
5.Equipped the other end of the wire with a corresponding 35 millimeter heat shrink sleeve on the isolation layer, and a 20 millimeter heat shrink sleeve on the outer side of the cable. Heat to fasten, and then clip the European style terminal to complete as shown below.
