OPTIONS OVERVIEWThe 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.

4 The PLT200 can be tripod mounted and Locked-On for accurate and continuous operation. This tachometer also stores minimum, maximum and last measurement in FEATURE LOCATIONSMin / Scroll Down arrowStart / Reset buttonMax / Scroll Up arrowLCD displayMenu / Select and Lock-on buttonBattery compartmentAVOID EXPOSURE - LASER BEAM IS EMITTED FROM THIS APERTUREO utput socketInput socketBelt clipTripod mounting bushing (underside) LCD DISPLAY SYMBOLSOn Target Indicator.

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 TACH ometer Setup1. Turn Power ON2. Enter Setup 3. Enter selection of Mode4. Select TACH Mode5.
