Electronic indicator with adjustable ratio of spindle displacement to displayed value
First Claim
1. An electronic indicator that internally scales all measurements by an adjustable displacement-to-display ratio, said electronic indicator comprising:
- (a) a housing;
(b) a transducer having a sleeve mounted within and extending from said housing, an axially reciprocating spindle extending from said sleeve and having a displacement relative to said sleeve, and a sensor measuring said displacement and providing a sensor measurement representative of said displacement;
(c) a controller within said housing, said controller receiving said sensor measurement and including sensor measurement scaling means for scaling said sensor measurement to an actual displacement in standard length units, display scaling means for scaling said actual displacement by said displacement-to-display ratio to obtain a display value, and adjustment means for adjusting said displacement-to-display ratio; and
(d) a display within said housing for displaying said display value.

Abstract
An electronic indicator that includes a means for a scaling the actual displacement of the spindle by a user-adjustable scale factor representing the ratio of the actual displacement of a spindle to the value displayed. The indicator includes a body, transducer assembly, controller, and display. The transducer outputs a value representing the spindle displacement to the controller. The controller converts the value to standard length units and scales the standard units by the desired ratio of the actual displacement to the displayed value, as set by the user prior to use of the indicator.

6. An electronic indicator that scales all measurements by an adjustable displacement-to-display ratio, said electronic indicator comprising:
-
(a) a housing including a body and a bezel rotatable mounted to said body; (b) a transducer having a sleeve mounted within and extending from said body, an axially reciprocating spindle extending from said sleeve and having a displacement relative to said sleeve, and a sensor measuring said displacement and providing a sensor measurement representative of said displacement; (c) a controller within said bezel, said controller including at least one pushbutton and a programmable processor for receiving said sensor measurement, said processor being programmed to scale said sensor measurement to an actual displacement in standard length units, to scale said actual displacement by said displacement-to-display ratio to obtain a display value, and to use said at least one pushbutton to for adjusting said displacement-to-display ratio; and (d) a display within said housing for displaying said display value. - View Dependent Claims (7)
