The unit activated by with an easy accessible button.
Activated by pressing the center of the front-side of the device.
By pressing the start button:
1. Produce an audible beep to indicate the countdown has started;
2. After 60 seconds a double audible beep produced indicating the 60 seconds’ period has passed and the visual indicator should cease indicting the unit has stopped counting down.
3. Provide red visual indicator informing the user that the device has been activated and is counting down (For example a flashing LED could indicate the unit is currently counting down.)
4. Pressing the button during an ongoing countdown reset the unit which means: stop the countdown and the visual indicator.
One audible signal (beep) at start and tow audible signal (Beep, Beep) at the end of the cycle.
Visual indication (red LED flashing) during operation and progress during the cycle. (Each second flashing, till the timer is stopped or when it completes the one minute count)
A provision included to ensure that the battery is not connected to the internal circuit at the time of delivery. This to avoid unwanted activation, leakage or accidental short-circuit of the unit.
The unit not make any sounds during the countdown (to avoid causing confusion for the person counting the breaths) .
Accuracy should be ± 0.1 second.
The unit battery powered and full batteries allow the unit to support 10 ,000 cycles of 60 seconds as a minimum.
The indicator LED integrated in the casing and not protruding.
It is used to demonstrate experiment of plant photosynthesis, respiration and transpiration. It consists of transparent container, funnel, top head, test tube, test tube rack and gas collecting cap.
