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. 
 
 

 

Ionizer

Conductive mat

Wrist strap

Conductive shoes

Conductive flooring (sheet)

Anti-static clothing

Conductive stool/chair
