Page 5: Introduction
INTRODUCTION The Pocket LED Strobe (PLS) is a rugged, portable battery powered LED (Light Emitting Diode) stroboscope used for inspection and to stop motion to determine the speed of rotating objects. The unit is ergonomically designed for comfortable hand held operation or it may be mounted on a tripod using the integral ¼... -
Page 6: User Interface
USER INTERFACE The Pocket LED Strobe has a two-line backlit alpha-numeric liquid crystal display (LCD) and a four-key keypad that enables the user to control the operation of the unit. The user interface is described in Figure 2 and Table 2. MENU Figure 2 Pocket LED Strobe User Interface Table 2 Pocket LED Strobe User Interface... -
Page 7: Getting Started
GETTING STARTED The Stroboscope may be hand held or mounted on a tripod or other user supplied bracket using the ¼-20 UNC bushing on the underside of the unit. 3.1 Power The LED Strobe is battery powered and has internal rechargeable batteries. -

4.1 Internal Mode The strobe is in the Internal Mode when nothing is plugged into the input jack. In the internal mode the strobe generates its own timing signals and the user can adjust the fl ash rate as described below. 4.1.1 Adjusting the Flash Rate - RPM The fl... -
Page 10: External Mode
4.2 External Mode In the External Input Mode the user can’t make any flash rate adjustments. The fl ash rate is a function of the input signal. This mode is used to synchronize the fl ash to an external event (for example, from an optical sensor) to stop or freeze motion. -

Page 15: Strobe Brightness
STROBE BRIGHTNESS The strobe’s brightness depends on how wide the strobe’s fl ash pulse is; the wider the pulse, the brighter the fl ash from the LEDs appears to be. There is however, a downside to the wider pulses. All strobes work by giving short bursts of light (the pulse width) at a rapid repetition rate (the fl... -

When setting the pulse duration in degrees, what you set is what you get. Refer to the image on the right for the difference between a 1° and 5° (of rotation) fl ash duration. There are two methods of adjusting the fl... -

remains constant*. The degree of rotation visible changes to keep the pulse width of the fl ash constant*. *Note: There are two limits maintained by the strobe – the pulse can never be greater than 1300 µs nor can it exceed 10° of rotation. The strobe automatically adjusts these values as the fl... - Page 18 of the actual speed. You will see 2 images of the key way at 2 times the actual speed, 3 key way at 3 times, etc. The FPM equals the shafts Revolutions Per Minute (RPM) at the highest fl ash rate that gives only one stationary image of the key way.

Page 19: Batteries
BATTERIES The Pocket LED Strobe is fi tted with a rechargeable Lithium Ion battery pack. These batteries are prone to self-discharge over time. For maximum performance, charge the batteries prior to use and do not store in hot loca- tions. The strobe uses an external charger. Allow 3-5 cycles of charging and discharging for batteries to reach full capacity. -
Page 20: Ba Ery Disposal
CAUTION: Use of rechargers other than the one supplied (Model LBC-U) will damage the stroboscope and void the warranty. DO NOT LEAVE A CHARGER THAT IS NOT PLUGGED INTO THE AC POWER CONNECTED TO THE STROBE. When charging, the strobe will indicate CHRGE in the bottom right of the display when turned on and then it will shut off. -
