11 Notes

1. Please pay attention to the compatibility of the tested medium and the shell when selecting the model. If you are not sure, please refer to the medium compatibility table on the back cover of the manual or consult our company.
2. When selecting digital display products, the working environment temperature range of the display head is -30ºC~60ºC, the product power supply should not be less than 15VDC.
3. Sealing measures are taken at the interface connection to prevent leakage of pressurized liquid and cause pollution or accidents.
4. When using in a dangerous environment such as flammable and explosive, please install a safety isolation barrier as required, and the cable connection must be sealed and reliable.
5. Tighten the junction box cover before energizing work to ensure that the inner cavity of the junction box is isolated from the environment.
6. When cleaning and repairing products, you need to power off, remove the transmitter,. live operation on site is strictly prohibited.
