1.0 OVERVIEW
The Pocket Laser Tach 200 is a multifunction Tachometer, Ratemeter,
Totalizer and Timer. It is programmable to read in English or Metric units.
An input socket accepts remote sensing devices and an output socket allows
for pulse output to external indicating devices. The PLT200 can be tripod
mounted and “Locked-On” for accurate and continuous operation. This
tachometer also stores minimum, maximum and last measurement in memory.

WARNING: Making measurements in direct contact with rotating
equipment can be dangerous. Keep all loose clothing and hair away from
exposed moving machinery. Keep the hand holding the instrument well
behind the back end of the Remote Contact Assembly. Properly replace
all machinery guards after completing measurement. Do not use for
rotation greater than 20,000 RPM.

7.0 TACHometer Mode
Tachometer measures speed or linear rate with respect to time. Time
intervals are sceonds, minutes, or hours. Rotational speed can be measured
in Revolutions (Revs) per second, per minute, or per hour. The most common
measurement is RPM or Revs per minute using the optical tachometer mode.

8.0 RATE Mode
Measurement of units in addition to Revs requires the attachment of the
Remote Contact Assembly and tips/wheels. With this attachment, the unit
can measure RATE inputs-revs, inches, feet, yards, centimeters and meters
either per second, per minute or per hour, as well as miles per hour.
NOTE: External Remote Contact Assembly (RCA) must be inserted into
input socket.

9.0 TOTALizer Mode
Totalizer accumulates input on an ongoing basis. In the simplest form the unit
acts as an optical counter, incrementing the display each time an input pulse
is sensed. Using the Remote ContactAssembly with various tips and wheels,
the unit can totalize in revs, inches, feet, yards, centimeters, and meters.

10.0 TIMER Mode
Accumulates time in minutes, seconds, and tenths of a second. There are two
modes of operation. The Manual mode operates like a stopwatch, the timing
period being started and stopped by the user. TheAuto mode can be stopped and
started by the user or a piece of reflective tape on objects. The user can freeze
the display-and view/record a LAPtime-at any time without affecting the count.
