On our PPM's we obtain a printout of the results for the equipment and follow the guidelines in the manuals. They should all have a daily monthly or annual test to be conducted. This is all attached to the job sheet that is filed. The database is then updated to say when the equipment was last seen and whether the equipment has had been calibrated or had its calibration checked.
There is the odd piece of equipment that gets a visual inspection and a tick to say it still exists but the manuals are used if available.
Its all about covering your arse if it comes to the court situation.
