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 led 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.

2.0 SAFETY PRECAUTIONS

All operators should wear safety goggles when using this or any other tachometer.
Failure to do so could result in serious injury!

1. Check condition of the mounting hubs of the cone tip, funnel tip, shaft extension
and surface speed wheel. Replace those that are worn, loose-tting or cracked.

2. When using the Surface Speed Wheel, make sure it ts the tachometer shaft snugly.
In operation, keep the wheel perpendicular and parallel to the moving surface to
prevent it from running off the tachometer shaft.

3. Store the instrument in its carrying case when it is not in use.

3.0 COMPLETE KIT

All models are supplied as a
complete kit that includes the
gauge, cone tip and funnel tip
adapters, shaft extension and
instruction manual, packaged
in a foam-tted carrying case.

NOTE: Calibration
Certicates are optional.

Pointer Button

Pin

Range Switch

(Top View)

1. Slide the Red Range Switch to select a multiplier for your application. If the
range is unknown, start at “x100” and adjust to lower range as needed. When
properly set, the needle will register a value between Min. and Max. on the dial.

2. Manually rotate the measuring shaft to engage the gear for the selected range.

3. Slide the measuring wheel contactadapter the over the shaft of the instrument.
Be sure to align the pin on the side of the shaft with the slot in the adapter.
Push on securely.

4. To begin measuring, bring the tip adapter into contact with the moving surface
of the material being measured. The gauge will take and display a reading,
either RPM, ft/min, min/min).

5. To lock in the reading, press and hold the Red Pointer Button to activate the
pointer. When the pointer button is released, the pointer will remain in the last
position.

6. To reset the pointer, press and release red button again.
