Working of “Intelligent Timer with Solenoid” With “Inclined Plane” and “Loop The Loop
Apparatus”
1. Connect the photo gates with the apparatus by using connecting lead (EPST male – EPST male).
Photo gate of “Inclined Plane” or “Loop The Loop Apparatus” which is connected on Gate 1 EPST
Female Socket on apparatus will act as IN Gate for passing object and the photo gate of “Inclined Plane”
or “Loop The Loop Apparatus” which is connected on Gate 2 EPST Female Socket on apparatus will act as
OUT Gate for passing object.
2. Select the working mode “Inclined Plane” or “Loop The Loop Apparatus” whichever is required at present.
3. Plug-in the power cord with an input of 90-240V AC.
4. Press the switch “MODE” once to select the mode of distance on the device.
5. Now press the “SET DISTANCE” key to set the distance as equal to the distance between photo gates, actually.
Resolution of the set distance is 100mm.
6. Now press the “MODE” switch again, to enter this device in “TIME” mode, as the object will enter from
gate1, the timer will start and as the object will exit through gate2, the timer will stop.
7. The result on LCD will be the time taken by an object to enter from gate1 and exit from gate2 within a
distance.
*The unit will be “SECOND” for this “TIME” result.
8. As again you will press the “MODE” key the device will enter in the “SPEED” mode and it will show you
the auto calculated result for the speed of that object which entered from gate1 and exit from gate2. This
calculation is done by the device through microcontroller programming.
9. Press the “MODE” key again, the device will enter in the “ACCELERATION” mode and it will show you the
auto calculated result for the acceleration of that object which entered from gate1 and exit from gate2. This
calculation is done by the device through microcontroller programming.
10. To store these results of “TIME, SPEED & ACCELERATION” you can press the “STORE MEMORY” key.
This device can store up to 10 results only.
11. Repeat all of above steps to obtain the more observations for your experiment.
12. Now you can press the “RESULT” key to see the “TIME, SPEED & ACCELERATION” together for all your
previous observations. Even after the power cut, your results will remain store.
13. To delete all the previous stored results, press the “STORE MEMORY” key continuous for 3 seconds, a
message for “DELETING...” then “MEMORY DELETED!!” will show up.
14. Press the “RESET” key to initialize the device again for new experiments.
(Press the “RESET” key, if any unexpected result shown during experiment.)
