1.0 INTRODUCTION
The new HTM mechanical hand-tachometer accurately measures RPM and surface
speed on a wide range of applications. Favored in several industries, including
elevator maintenance, mining and others, HTM mechanical tachometers use a
pointer and dial to display RPM or surface speed—without the need for batteries.
Four models are available (two English and two metric):
HTM-100F 10-10,000 rpm/5-5,000 ft/min
HTM-100M 10-10,000 rpm/1-1,000 m/min
HTM-500F 30-50,000 rpm/15-25,000 ft/min
HTM-500M 30-50,000 rpm/3-5,000 m/min
1.1 Unpacking
Unpack the gauge and inspect it for any shipping damage. Notices of defect must
be iled immediately, in writing, at the latest within 10 days on receipt of the goods.
1.2 Applications
RPM: Used to measure the speed of rotating motors, shafts, pulleys, gears, etc.
Linear Speed: Used to measure the linear speed of moving surfaces, such as
conveyor belts, printed materials, webs of fabric or paper, etc.
