10.0 CHARGING
WARNING - This product emits a visible beam of laser
light. Avoid exposure to the laser radiation. The use of
optical viewing aids (binoculars, for example) may
increase the ocular hazard.
CAUTION - The laser beam should not be intentionally
aimed at people or animals.
CAUTION - Use of controls or adjustments or
performance of procedures other than those specified
herein may result in hazardous radiation exposure.
WARNING - Use only the “PR Universal” charger supplied
with the product.
Read and follow all instructions in this manual carefully,
and retain this manual for future reference.
Do not use this instrument in any manner inconsistent
with these operating instructions or under any
conditions that exceed the environmental specifications
stated.
This instrument is not user serviceable. For technical
assistance, contact the sales organization from which
you purchased the product.
Slide the Power switch (8) to the Off/Charge position and plug in the
charger. The Power LED (4) will blink red while the unit is fast charging.
The Power LED will blink amber when slow (trickle) charging. It will be
solid amber when the batteries are fully charged.
Note: If the charger is plugged in when the Power switch is the on
position, the batteries will be trickle charged during operation.
CAUTION: Use only the supplied PR-Universal charger with the
sensor.

To change the setting, move the Polarity switch (5) to the left (positive
pulse) for a white target or to the right (negative pulse) for a black target.
Turn the Sensitivity Adjust knob (7) to Max. Press and hold the Learn/
Gain button (6) until the Auto/Gain LED (3) blinks.
8.0 AIMING THE LASER
The proper operation of the Laser Sensor is dependent upon the alignment
to and reflectivity of the target. In order to aim the beam it is necessary to
stand behind the sensor and view the target along the plane of the beam. Do
not stare directly into the laser beam or the reflected light. For targets
greater than 5 feet and up to 65 feet from the sensor, mount the laser on a
tripod using the ¼ - 20 bushing on the bottom of the unit and attach T-5
reflective tape to the target.
To aid in locating the laser dot over a large distance, hold a piece of white
cardboard or equivalent in front of the laser. Progressively move the white
surface closer to the desired target. Then adjust the aim of the laser as
necessary.
In areas of high ambient light (outdoors), performance can be enhanced at
long distances by slipping a piece of black tube with a minimum inner
diameter of 0.6 inches, over the nose piece to act as an extension nose piece.
This tube should not deflect the beam in any way.
9.0 RS232
Baud rate = 9600, 8 bits, 1 stop bit, no parity.
When the unit is turned on, it will send out: “SLS<lf><cr>Vx.x<lf><cr>
0.0<cr>”. Where <lf> is the linefeed character, <cr> is a carriage return
character, and x.x is the firmware version number.
The unit will send out the current RPM as a right justified 7-digit ASCII
number that will always include a decimal point followed by carriage return.
The update rate is a function of the speed of the target and will not exceed
twice per second.
