3. Installation and attention
First closed the pipe value of the installation site, then use ribbons wrapped around the sensor on the sensor screw; Screwing in the sensor to the pipeline
Second: Open pipe valves to confirm whether there is no leakage phenomenon.
2. Battery change
(1) As shown in Configuration diagram, unscrew the back cover, battery connected through white plug and socket. The connector with lock and clear direction, please pay attention to use;
(2) When battery connected to the return circuit, liquid crystal display normally, means the battery connected successfully;
(3) Screw the back cover
(1) Sensor daily maintenance, mainly change the battery. Can get the battery voltage information via remote wireless acquisition, can also be observed in the liquid crystal, when the battery voltage is lower than 2.6 V, you need to replace the battery.
(2) If sensor do not use for a long time, please disconnect the battery.
(3) Battery access way as already described, the antenna is in the battery back cover, open the battery cover can saw it. When battery connected, return back the cover
