The front panel LED: red represents temperature collection status and sleep to wake up,
Front panel reset: by magnet, right in front of the shell cover, the magnet to reset up the arrow and remove the magnet stability for 3 to 5 seconds, LED red light flashes three times, liquid crystal display 8888 synchronous flash three times, also on behalf of the instrument reset successfully, the main purpose of the reset it is changed into the instrument internal parameters, or refresh the pressure value, and build up a network link to refresh.
5. Installation instructions
5.1. All transmitter through digital calibration, the different between the transmitter has the complete consistency and interchangeability;
5.2. In transit, all of the transmitter battery is in the off state, pressure transmitter installation on site, need to unscrew header back cover, open the battery switch, attention should be paid to tighten sheath, prevent leaking;
5.3. Pipeline and often stop well installed wireless cellular network pressure transmitter, pressure transmitter will be ready to install on the pipe first valve type needle valve or gate valve closed, and then there are two installation method: (1) the pressure transmitter directly screwing in type needle valve port; (2) will live or port adapter type screwing in the needle valve, then transfer transmitter screwing in live or joint on port, this kind of installation method to increase the living or connector to adjust the direction. Type installed, open the needle valve valve to confirm no leakage phenomenon, namely the installation qualification;
5.4. The cellular network wireless pressure transmitter after the installation is complete, can through the keys or debugging tools for network parameter Settings.
5.5. Transducer without using for a long time, can through the debugging tools set pressure transmitter to sleep patterns, (transmitter in the process of the factory warehouse, unified set to sleep mode or closed, the need to adjust and activation can be normal use). Debugging software interface online list below:
6. Matters needing attention
6.1. This product is the battery model used for ER34615H - 3.6 V38Ah; It is prohibited to use other model battery.
6.2. Product antenna casing for the plastic material, potentially dangerous electrostatic charge! Use should be avoided in the friction! Please use wet cloth to wipe clean!
