Question:

Where does the meter check the pressure gauge? How long is the training time?.

Where does the meter check the pressure gauge? How long is the training time?.

Answer:

Routine test items and regulations of pressure gauges1, appearance inspection1.1 assembly of pressure gauge parts should be firm and free of looseness.1.2 the newly made pressure gauge should be even and smooth with no obvious stripping.1.3 pressure gauge should have safety hole, safety hole must have dust-proof device. (media not allowed to be spilled outside the pressure gauge outside the table)1.4 pressure gauge on the indexing disc should have the following marks, manufacturing units or product name; trademark; units of measurement and digital measurement equipment manufacturing license mark and number, vacuum gauge should be "-" or "negative", the level of accuracy of the serial number.1.5 readings shall be colorless and transparent and shall not contain defects that interfere with readings. The indexing plate shall be level and smooth with distinct marks.The 1.6 pointer shall cover the minimum length of the index line 1/3~2/3, and the width of the pointer indicating end shall not be greater than the width of the graduation line.1.7 accuracy levels are 1, 1.6, 2.5, 4.1.8 zero, with a check of the gauge pin, without pressure or vacuum, the pointer should be close to the stop pin, "indented" should not exceed the allowable error value specified in Table 1, the pressure gauge without stop pin, without pressure or vacuum, corresponding to the zero mark pointer, zero mark should be 2 times the allowable error absolute value specified in table 1.
Where the metering and testing center is available, they will regularly train and collect evidence. Consult your location's measuring and testing center!
The Quality Supervision Bureau has a metering office where it can be trained
