1. Product shall not be used to test mediums that not compatible with stainless steel;

2. Make sure power supply is conformed with power requirements of the probe, and positive and negative wiring connection correct. Ensure max pressure of the medium is in range of the product capacity;

3. During measurement, please exert or release the pressure slowly to prevent a high or low pressure occurred in very short time;

4. In case of medium spout, disconnect the pressure source before probe disassembly.

5. To avoid damage caused by misusage, please DO NOT disassemble the product or touch the diaphragm.
