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.

The instrument will provide six to eight hours of continuous operation on a single set of batteries, depending on the type used. The instrument is provided with a built-in charging network, which works in conjunction with the optional NiCad batteries. The optional recharger plugs into the single jack located next to the optical lens at the front end of the instrument.

Fourteen to sixteen hours is required for a complete recharge. When the battery voltage in the Phasar-Tach is getting low, the display will blink

“LO BAT” to indicate that the batteries need to be replaced.

NOTE: Only use model R-5B (115 Vac) or R-6B (230 Vac) rechargers with NiCad batteries. Do not attempt to charge non-rechargeable batteries.

ALWAYS DISPOSE OF BATTERIES IN A SAFE AND RESPONSIBLE

MANNER.

CLEANING

To clean the instrument, wipe with a damp cloth using mild soapy solution.

OVERVIEW

Each Phasar-Tach model combines the accuracy and safety of a non-contact optical tachometer with the convenience and ease of operation of a pistol grip instrument. The instrument provides non-contact measurement of rotational speed to an accuracy of .01% of reading. It reads RPM directly to the nearest RPM, and a ‘on-target’ indicator is provided to verify the instrument is properly aligned on a target and receiving valid information.

OPERATION

The Tachometer measures rotational speed from a single pulse per revolution.

This pulse is supplied by marking the rotating shaft with reflective tape in an easily accessible location. The Tachometer is equipped with a built-in incandescent or laser light source providing a beam which is aimed at the reflective tape located on the rotating shaft. The pulse from the reflective tape is received back through a single lens reflex optical system and detected by a photocell inside the instrument. The Tachometer then computes the rotational speed and displays it to a resolution of 1 RPM.

To operate the Phasar-Tach, simply aim it at the reflective tape while holding it at a distance of 1 inch [25.4 mm] to 3 feet [0.9 m] for incandescent lamp units or up to 15 feet [4.6 m] for laser units (observe laser safety precautions). Squeeze the pistol grip trigger, and read the indicated speed.

The on-target indicator must be on. The display is updated twice per second.

2

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. However, with this small tape size, it would be necessary to operate the instrument very close to the rotating shaft and insure it is held steady. For normal operation, a tape size of approximately 1/2 inch [12.7 mm] square or larger is recommended, and on very large diameter shafts or for very high-speed applications, a larger size piece of tape may be required. It is also recommended that the reflective tape be viewed just slightly off the perpendicular. The Tachometer will operate at angles from 0 to 45 degrees, but best results are obtained by aiming the instrument at the reflective tape at approximately a 10 to 20 degree angle. This insures that only pulses from the reflective tape are received by the tachometer and minimizes the problem of interference from a highly polished surface or varying ambient lighting.

USING THE PHASAR-TACH WITH AN REMOTE OPTICAL

SENSOR (ROS-5P)

The -R version of the tachometer has a provision for using the optional

ROS-5P Remote Optical Sensor. In addition to the standard built-in optics, a 1/8 inch [3.5 mm] phone plug is provided on the front panel to accept an

ROS-5P Remote Optical Sensor. A toggle switch on the optics panel selects internal or remote operation.

For applications requiring the ROS-5P Remote Optical Sensor, move the

Remote/Internal switch to the remote position to disable the internal optics of the Tachometer. When the trigger is pulled or latched, the ROS-5P

3

Remote Optical Sensor can be used for measurements. The ROS-5P operates

3 feet [0.9 m] and ±45° from the reflective tape.

NOTE: The standard ROS-5P cable length is 8 feet [2.4 m]. Longer cables up to 100 feet [30.5 m] are available.

CALIBRATION AND SELF-TEST

The Tachometer is a crystal controlled digital instrument that requires no calibration. However, the accuracy of the instrument can be checked at any time by aiming it at an old style fluorescent light and observing 7200 ±2

RPM. In countries with 50 Hz. power line frequency, the display will read

6000 ±2 RPM.

NOTE: The Tachometer will not read on energy-efficient fluorescent lights.
