BATTERIES  
The Tachometer operates from four ‘AAsize 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.  
Dimensions (LxWxH):6.13” x 3.25” x 1.75 “ plus 4.75” handle

OVERVIEW  
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.  
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  
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.  
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.  
ALWAYS DISPOSE OF BATTERIES INASAFEAND RESPONSIBLE  
MANNER.  
CLEANING  
To clean the instrument, wipe with a damp cloth using mild soapy solution.  
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.

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.  
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  
When the trigger is released, the Tachometer will hold the last measurement  
taken and display it for up 90 seconds.  
up to 100 feet [30.5 m] are available.  
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)  
CALIBRATIONAND SELF-TEST  
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. Atoggle switch on the optics panel selects  
internal or remote operation.  
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.  
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  
NOTE: The Tachometer will not read on energy-efficient fluorescent lights.
