Type B Pressure Meter Troubleshooting 1

[poltroon]

I have been calibrating our labs inventory of these every 3 months (we have 12 pressure meters) and I am trying to find a troubleshooting guide so I can start making the technicians calibrate their own equipment. I can obviously make one up myself but figured maybe someone had one I could use or a link.

I think that having the techs calibrate their own equipment is not a great idea. Centralized calibration, even if you rotate the duty among all your techs for familiarity, is a better measure of internal quality assurance.

I think it is a good idea that the techs carry an air meter calibration kit and tools with them. Nothing stops arguments quicker than a 5 minute air meter calibration check.

As for trouble-shooting, that is a different area of concern. Techs need to know how to field-strip a guage, then check the calibration. It is not something I would recommend be done with a pamphlet, but should be demonstrated at a morning tail-board, then practiced by the techs. Show them what happens when air is observed leaking from the different trouble spots.

Tools required need to be nothing more advanced than a flat screwdriver and a couple of box wrenches.

This needs to be followed up with the three month calibration or as-required by the examination body.

What is the accreditation body (example A2LA, IAS, AASHTO) requirement regarding calibration? Most ABs require that you have procedures in place for this sort of thing.
