SPECIFICATIONS OPTIONS AND ACCESSORIES This product is designed for indoor or outdoor use under the following conditions (per IEC1010-1): ROS-5P* Remote Optical Sensor with 8 foot [2.4 m] cable and mounting bracket Speed Range: 5 RPM to 100,000 RPM Accuracy: ± 1 RPM or .01% of reading Resolution: 1 RPM Display: 6-digit 0.45” high liquid crystal Display Update: Twice per second On-Target Indication: Target (Bullseye) on lower left of display Operating Distance: Range: 1 inch [25.4 mm] to 3 feet [0.
BATTERIES The Tachometer operates from four ‘AA’ size batteries which are located under the hinged top of the instrument. To access these batteries, grip the tapered cover at the optical lens end of the instrument and pull up. The cover is hinged at the display end of the instrument and pivots fully out of the way. It may also be convenient to keep a spare supply of reflective tape in the free area underneath this cover.
For longer duration measurements, the trigger latch on the side of the pistol grip handle can be depressed after pulling the trigger, and the instrument may be mounted on the 1/4-20 threaded bushing at the base of the handle. When the trigger is released, the Tachometer will hold the last measurement taken and display it for up 90 seconds. On very small shafts, the Phasar-Tach will work down to a reflective tape size of approximately 1/8 inch [3.2 mm] square.
