1 The typical value is a representative or standard value. It is not strictly warranted.
2 Make sure that the peak AC voltage does not exceed 350 V and that the DC voltage does not exceed 250 V when the
frequency is 1 kHz or less.
3 Because the fuses used by this instrument are all inside the case, you cannot replace them yourself. If you believe that the
fuse inside the case has blown, please contact your nearest YOKOGAWA dealer.
