5. Switch on the transmitter's laser ([11] and [10]). A red dot will show
where it is aimed at.
6. Adjust the angle of the sensor block horizontally and vertically ([9] and
[7]) until the red dot is centred on the receiver and both the receiver's
LEDs ([2] and [3]) go out.
7. You may have to adjust the angle of the receiver's sensor block a little
as well.
8. Turn the transmitter's laser off.
9. Put the covers back on the units.
Fine-tuning the Receiver
1. Take the cover off the receiver.
2. The units can be fine tuned using a volt-ohm meter (VOM).
3. Set the range of the VOM to 0~10V DC.
4. Measure the voltage over the + and - measuring points [4] on the
receiver.
5. Adjust the angle of the sensor block until the VOM measures the
highest voltage.
6. 2.5 to 5 V is OK, 5 to 8 V is best.
7. Put the cover back on the receiver.
Delay Time
1. Take the cover off the receiver.
2. Adjust the delay time with the knob on the receiver [5].
Objects passing faster than the selected delay time will not be
detected.
A delay time of 50 ms corresponds to someone running by at full
speed.
A delay time of 700 ms corresponds to someone walking by.
3. Put the cover back on the receiver.
When finished tuning and adjusting the units, put the covers back on and fix
them with the bottom screw.
