General Tools and Instruments LT2234C - Manual (Page 3)

INTRODUCTION
Thank you for purchasing General Tools & Instruments’ Model
LT2234C Non-Contact Tachometer. Please read this user’s
manual carefully and thoroughly before using the instrument.
The LT2234C is a general-purpose handheld instrument that
can measure the rotational speed of a motor’s or generator’s
spinning shaft. It does so by bouncing a laser beam off a
piece of reflective tape affixed to the shaft and using an in-
tegrated photocell to count the number of reflections pro-
duced per minute. 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 can be
stored, indexed and recalled, along with the last value, the
minimum value and the maximum value of a series. Thanks
to its five-digit display and the use of a non-contact meas-
urement technique, the tachometer can measure the speeds
of shafts spinning at up to 99,999 rpm.
The LT2234C is powered by three “AAA” batteries (included).
