● Peripheral devices must be properly grounded so that no surges are applied to the product by a leakage
voltage. Do not allow a voltage exceeding the absolute maximum ratings to be applied to the product from
the measurement instrument, etc. (This tends to occur during ON/OFF switching of power sources, so use
caution.) If there is the possibility of a surge voltage, insert a filter (made up of a resistor and capacitor) to
protect the product. During operation do not attach or detach any connector, etc. that are connected to the
power supply line or output line.
(3) Carrying, storage and packing
Place the MS series and micro-spectrometers in a conductive case by inserting the leads into the conductive
mat (for shorting leads). For the RC series (head type), put the product in a conductive case. The PC board
to mount the head type should also be put in a conductive case. Avoid using plastic or styrofoam as they
may generate static electricity by vibration during shipping, etc. causing breakdown or deterioration of the
heed type.
Use a conductive carrying case and storage shelf.
Avoid storing the product near equipment that may generate high voltage or high electromagnetic fields.
When packing the product, short the leads so that they are at the same electrical potential, and use
conductive packing materials.
Note: It is not always necessary to provide all the anti-electrostatic measures stated above. Implement these
measures according to the extent of deterioration or damage that may occur.

3-2. Precautions for designing the circuit board
Driver circuits for mini-spectrometers are unique in that they contain a light input section and both digital and
analog circuits, so take the following precautions when designing the circuit board.
