Introduction - General PCT2236B User Manual

INTRODUCTION

Thank you for purchasing General Tools & Instruments'
PCT2236B Combination Contact/Non-Contact Laser
Tachometer. Please read this user's manual carefully and
thoroughly before using the instrument.
The PCT2236B is a general-purpose instrument that can
measure the rotational speed of a motor's or generator's
spinning shaft using either a contact or non-contact technique.
In non-contact measurement mode, the instrument bounces a
laser beam off a piece of reflective tape that has been affixed to
the shaft and uses an integrated photocell to count the number
of reflections produced per minute. In contact measurement
mode, the instrument uses dedicated fittings that measure the
speed of the shaft by rotating along with it. In contact mode, the
PCT2236B also can measure the linear speed of a moving
surface (such as a conveyor belt or the circumference of a
wheel) and the dimensions of stationary objects.
In both operating modes, measurements are displayed in real
time on a 0.7 in. (18mm) high backlit liquid-crystal display and
stored in memory. Up to 96 measurements of rpm or linear
speed can be stored, indexed and recalled, along with the last
value, the minimum value and the maximum value of a series.
In non-contact mode, the tachometer can measure the speeds
of shafts spinning at up to 99,999 rpm. In contact mode, the
instrument can measure rotational speeds from 0 to 20,000 rpm,
linear speeds from 5cm/min (2 in./min) to 2km/min (6,562
ft./min), and lengths from 5cm to 10km (2 in. to 6.2 miles).
The PCT2236B is powered by four "AA" batteries (included) or
an optional 6V AC/DC adapter.
