Use, maintenance, and overhaul
1. The instrument should be installed in the surrounding environment of -25 ℃~55 ℃, with a relative temperature not exceeding 85% and an altitude below 2000m. At the installation location, the monthly average temperature should not exceed+30 ℃. Due to temperature changes, frost is allowed to form on the surface of the pressure gauge, and the temperature of the measured medium should be less than 70 ℃. (If used for measuring high-temperature media such as steam, a temperature resistant and explosion-proof electric contact thermometer should be selected).

2. The instrument must be installed vertically and strive to maintain the same horizontal position as the measuring point, otherwise additional errors caused by liquid level differences should be included.

3. After connecting the electrical circuit of the instrument, carefully check and perform a trial operation.

4. The instrument pressure section generally uses a temperature upper limit of 3/4.

5. When adjusting the instrument order (adjust the upper and lower limit pointers to the given value by adjusting the knob), adjust the offline set value first and then the online set value.

6. When opening the outlet box or adjusting the given value range, the power must be cut off before proceeding.
