It is important, for accurate readings, that your SUN inclinometer (1) is mounted to a true vertical surface, (2) operates within the temperature range shown on this website's Inclinometer Specifications page, and (3) operates in a vibration-free environment. Vibration can cause static electricity, which can inhibit movement of the indicator ball. If mounting your angle gauge with the provided pressure-sensitive tape, the mounting surface should be at or above 60 degrees F (16 degrees C). If mounting with tape, clean the mounting surface with Isopropyl alcohol or other grease cutting cleaner, so the surface is free of dirt, grime, oil and grease. Surface must be dry. Mounting member must be at true vertical.* Once the inclinometer is in the desired location (with indicatorball at zero), press the tilt gauge firmly against the mounting surface to set the adhesive.
* We offer an inclinometer bracket, Item #2000-I, which allows true vertical-surface mount.
