• Do not point laser directly at eye. Use caution around reflective surfaces. Keep out of reach of children. WHAT’S IN THE CASE The PCT2236B comes fully assembled in a carrying case along with the following accessories (see Figure 1):... - Page 5 • Three rubber fittings—called rpm adapters—for making contact with the end of a rotating shaft of a motor or generator. Two have cone-shaped rubber tips that fit into a hollowed (concave) end of a metal shaft; one (B) has a large cone compatible with a 1/2 in.

OPERATING INSTRUCTIONS SIMULATE MAKING, STORING AND RECALLING RPM MEASUREMENTS IN CONTACT MODE Before using the PCT2236B on actual equipment, General suggests that you familiarize yourself with the way the instrument measures, stores and recalls speeds by spinning the tachometer’s shaft by hand. By simulating readings you can expect to see in practice, you will safely gain expertise that will save you time later. - Page 8 thumb. Note that this illuminates the display window. The display should show “0”, either with the letters “rpm” directly below it or with the letters “m/min” below it to the left, depending on the position of the function switch. To simulate a speed measurement, keep the tachometer cradled in your right hand and spin its shaft by “flicking”...
- Page 9 To simulate recalling stored measurements, press the MEM button once and hold it. This illuminates the display, which now shows the highest of the three readings you have just stored. Note that if you continue holding the MEM button, the display alternates between showing the highest value and the letters “UP”, signifying the maximum speed.
- Page 10 To complete this simulation exercise and put your new expertise to the test, make and store a set of five simulated measurements by hand-spinning the tachometer’s shaft and using the MEM button. Then , remembering not to press the Measurement button, press and hold the MEM button as ma ny times as needed to make the display go into countdown mode.

MAKING RPM MEASUREMENTS IN NON-CONTACT MODE To use the PCT2236B to make non-contact rpm measurements, you must first remove the black plastic housing at the top of the instrument that covers the laser light source and lens. - Page 14 Caution: The Phillips head screws securing both the housing and the battery compartment cover are not equipped with retainers, so they are easy to lose. The PCT2236B includes three spare screws designed to serve both purposes. To measure the rotational speed of a motor/generator shaft: 1.
