DT-200LR-S12 Handheld Digital Laser TachometerOperation Manual• When using the 12” wheel, do not use the extension shaft - the wheelmay fly off the shaft and cause damage.• Although the tachometer alone is able to achieve the higherranges listed in the Range and Accuracy table on page 3, the wheelattachment has a maximum speed limitation of 5,000 FPM (for safetyreasons).• Laser radiation may be harmful to the human eye. Avoid directexposure of human eyes to laser light. Eye damage can result.• Never point the unit at another person.• Keep out of the reach of children.• Avoid indirect exposure via reflective materials such as glass andmirrors.SPECIFICATIONSDisplay Range: 6 - 99,999 rpmAccuracy: ±1 rpm: 6 -8,300 rpm; ±2 rpm: 8,300 - 25,000 rpm;±0.006% of reading ±1 digit (±6 rpm max.) 25,000 - 99,999 rpmDisplay: 5 digit 0.4” (10 mm) high LEDMeasuring Units: rpm (on contact using adapter, included) forYPM, mPM, FPM, IPM, and Length: YRD, m, FT and IN; Use wheelwith 200L adapterMeasuring Distance: 1” (25.4mm) to 20’ (6m)Memory System: 13 readings are stored in memory and retainedfor 5 minutes (last, max., min., and 10 extra measurements)Detection: Laser diode / contactUpdate Time: 1 second (typical)Power Requirement: 2 AA 1.5V batteries (Life: Approx. 25 hrs)Operating Temperature: 32º - 113ºF (0º - 45ºC)Construction: Die-cast aluminum housingProduct Weight: 0.8 lb (365 g)Package Weight: Approx. 2 lb (.91 kg)Approvals: CEDimensions: 6.6” L x 2.4” W x 1.8”H (167.5 mm x 60 mm x 46mm); with contact adapter: Length=8.25” (209 mm)Warranty: 2-YearIncluded Accessories: Reflective tape, 2 cone adapters, funneladapter, 3½” extension shaft, carrying case, NIST certificate, mas-ter wheel (12” cir.) & contact adapterSeries DT-200LR Combination Contact/Non-Contact Laser Ta-chometers Laser-enabled precise RPM measurement up to 20feet. The Series DT-200LR digital tachometers incorporate lasertechnology yet retain our hallmark rugged construction and reli-able quality components. Units offer incredible value and versa-tility as they can operate in non-contact and contact applications.These instruments feature a field-upgradeable contact adapter forlinear rate measure, conveniently allowing both non-contact andcontact measurements. Incorporating the precise laser technol-ogy and user-friendly functions as the DT-200LR tachometer, theDT-200LR-S12 provides an exceptional accuracy in measuringspeed and length via its 12” wheel. The larger wheel rotates moreslowly than a standard 6” wheel, enabling reliable and safe regis-tration of high speeds.All Series 200LR units come standard with a NIST traceable cali-bration certificate. We’re confident you’ll agree that these fine unitsare the most advanced handheld tachometers on the market!DT-205LR-S12LCD DisplayDT-207LR-S12LED DisplayWhen power button is depressed,laser is active.99 Washington StreetMelrose, MA 02176Phone 781-665-1400Toll Free 1-800-517-8431Visit us at www.TestEquipmentDepot.com
