Any marks on the surface, such as scratches, grease, dust or finger

marks, will invalidate the calibration value assigned to the standard.

It is important that the calibration tile has an up-to-date certificate and

the normal renewal period is 12 months. However, it should be noted

that if successive calibration certificates give the same value for the

tile, extension of the renewal period to 24 months is permitted. The

tile must be calibrated at all angles when it is to be used with dual or

triple angle gauges.

Calibration tiles can be re-calibrated by returning the tile to

Elcometer, your local Elcometer supplier or to a recognised gloss

calibration facility such as BAM (Germany) or NRC (Canada).

6.2 Gauge

The Elcometer 401 should always be checked to ensure that the

metal base is clean. Care must be taken to ensure that the base

remains free of any damage. The optical cavities and lenses must

also be free of dust or any other contamination.

The gauge is supplied with two replacement lamp assemblies. To

change the lamp, follow the instructions given below for the

appropriate model.
