SD card sold in commercial stores

Question

Why are the SD cards sold in commercial stores not recommended for use with HIOKI products?

Answer

HIOKI's optional SD cards are designed for industrial use and are not sold commercially.
Commercially sold SD cards are designed to save the large files (in 10's of MB) such as pictures and videos.
On the other hand,  measuring instruments primarily save smaller data files (few kB).
Even if the general SD cards function normally with your instrument, it may stop saving data suddenly and without warning.
Please use our optional SD cards which are confirmed to provide proper and continuous saving.
