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 handheld 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 the table below. -
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. Power The LED Strobe is battery powered and has internal rechargeable batteries. -

Common (GND) Signal Input +3.2V Out to +3.2V Out to Sensor Sensor Signal Input Common (GND) Figure 3 Input Connector Detail (Stereo Plug) Common (GND) Signal Output Common (GND) Figure 4 Output Connector Detail (Mono plug) With no external input, the output jack provides a TTL compatible pulse from the strobe’s internal oscillator. -
Page 9: Internal Strobe Mode
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 flash rate as described below. 4.1.1 Adjusting the Flash Rate - RPM The flash rate can be adjusted by pressing the large UP/DOWN button. -
Page 10: External Mode
4.2 External Mode In the External Input Mode the user can’t make any flash rate adjustments. The flash rate is a function of the input signal. This mode is used to synchronize the flash to an external event (for example, from an optical sensor) to stop or freeze motion. -
Page 11: Menu Options
SETUP MENU OPTIONS To enter the Setup Mode it is necessary to press the MENU button twice. The first press will enter the x2 /2 mode as described in Section 4.1.2; the second press will enter the Setup Mode. The top line of the display will show SEtUP and the bottom line will show the setup options. -

Press MENU to select, use the UP/DOWN button ▲▼ to select on or off. As the status changes, the backlight will activate accordingly. BKLIT Press MENU to save and exit back to the main menu. 5.7 DECPT (Decimal Point) Set the number of decimal places to display. -
Page 15: Strobe Brightness
STROBE BRIGHTNESS The strobe’s brightness depends on how wide the strobe’s flash pulse is; the wider the pulse, the brighter the flash 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 flash rate). -
Page 16: Brightness In Degrees Of Rotation
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) flash duration. There are two methods of adjusting the flash pulse width and hence the brightness and consequently the blur. -
Page 17: Using The Stroboscope To Measure Rpm
*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 flash rate is increased or decreased to maintain these limits at all times. USING THE STROBOSCOPE TO MEASURE RPM The primary use for a stroboscope is to stop motion for diagnostic inspection purposes. - Page 18 Stopped Image 1/4 times 1/2 times 1 time 2 times 3 times 4 times Flash Rate (FPM) 1250 2500 5000 10000 15000 20000 Example: Object Rotating at 3000 RPM If the speed is outside the full scale range of the stroboscope (300,000 FPM), it can be measured using the method of harmonics and multipoint calculation.

Page 19: Batteries
BATTERIES The Pocket LED Strobe is fitted 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 locations. The strobe uses an external charger. Allow 3-5 cycles of charging and discharging for batteries to reach full capacity. -
Page 20: Battery 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. -
