PRECAUTIONS
(a) Power supply: Transient electric spike may cause a damage to the photodiode or IC chips.
A surge-free power supply and a slow starter circuit should be used.
To avoid causing an electrical surge, pins should not be connected or disconnected on the test fixture
before turning the power off.
(b) The product should be grounded for obtaininng the performance.
