tighten both sides with the attached screws.
1)Power connection
Connect power to connector terminals Nos. 17 or U and 18 or V(+).
Use a DC voltage of 5V±10% (AI-406-11, AI-406-12) and 12V±10%
(AI-406-22)
(Note that because this instrument is not provided with a power
supply switch, it starts operating when power is supplied.)
