Manual Controlled Tester
Angular Adjustment Of Vertical Shaft And Counter Weights
Note:
The rocker arm 'H' is constructed so that the vertical shaft 'K' may be set out of perpendicular, in order to get corresponding cycle readings at both high and low elevations on a single specimen.
It has been set prior to shipment (see sketch below). In the event that the user would change this angle, it would be necessary to add additional weight, such as a washer, around the vertical Shaft or additional weight to the projection of rocker arm to the left of Fulcrum, in order to maintain the 275 grams load exerted on paper at bottom of 'O' ring.

New Subject:
Without changing angle and by adding weight to the left of Fulcrum, enough weight can be added to reduce the standard 275 grams pressure exerted at bottom of 'O' Ring, which may, in very unusual cases, be desirable if testing for improving a finish that shows extremely low wear quality. This should, if proper Counter Balance Weight is added, effect a non-standard but higher cycle count, which may be useful in determining wear effect due to material or process changes on extremely low wear quality finishing materials, I.E.; hot stamped bright foil.
