1 Make sure the ACpeak voltage does not exceed 350 V and the DC voltage does not exceed 250 V when the frequency is
1kHz or less.
2 Because all the fuses used by this instrument are inside the case, the user cannot exchange them. If you believe a fuse inside
the case is blown, contact your nearest YOKOGAWA dealer.
