1. Before installation, check whether the model, specification and accuracy level of the instrument meet the requirements of the instrument. Check whether the joint thread of the instrument is consistent with the female thread installed.
2, the pressure gauge should be installed vertically, the inclination is generally not more than 30°, and try to keep the same level with the measuring point, so as not to bring an indication error.
3. After installation, under the condition of no pressure, observe whether the pointer is at zero or close to the disk stopper, otherwise it is not suitable for use.
4, when measuring the steam pressure, the lower end of the pressure gauge should be equipped with a ring tube, the use of water to transfer the steam pressure, in order to avoid high temperature steam rushed into the spring tube, affect the accuracy of the instrument, or accidentally make solder melt, resulting in meter leakage, accidents or scalded people.
