USE

 Hold the wheel by its central spindle. Begin at maximum thickness to reduce risk of inaccuracy caused by surface tension. Roll the wheel through the wet film with the side 1 in the diagram touching the substrate. Roll for at least one whole turn and slowly enough for wetting to occur. Roll the wheel backwards by at least on complete turn. The wet film thickness is read from the scale, at the end of the wetted segment of the middle circle, 2 in the diagram To use wheel on pipes, measure across the longitudinal axis (lengthways) of the pipe. On rough surfaces, measurements will be made from the surface peaks and represent the minimum wet film thickness.

SPECIAL CARE

 • Though robust in design, this instrument is precision-machined. Never drop it or knock it over

• Always clean the instrument after use.

• Clean the instrument using a soft dry cloth. Never clean the instrument by any mechanical means such as a wire brush or abrasive paper. This may cause, just like the use of aggressive cleaning agents, permanent damage.

• Always keep the instrument in its pouch when not in use.
