WARNING
• Turn off the power supply to the object to be tested before connecting it
to the instrument. It is extremely dangerous to connect and disconnect
measurement lead cables while power is being supplied to the object.
• It is extremely dangerous to incorrectly connect the voltage input terminal H
and the current input terminal mA. Make sure that the measurement function
(FUNCTION) selection and terminal connections are correct. An incorrect con-
nection may not only cause damage to the circuit or device under test and the
instrument, but also result in injury to the operator.
• The maximum allowable applied voltage for the grounding of all input/output
terminals is 42 Vpeak. Be sure not to exceed this voltage because doing so
may not only cause damage to the instrument, but also result in injury to the
operator.
CAUTION
About the Fuse
There is a built-in current input protection fuse for the current input terminal.
The fuse blows when an excessive current flows. If the fuse does blow, be sure
to replace it with the designated fuse (model: A1566EF). For details on the pro-
cedure for replacing the fuse, refer to “3.2.4 Fuse.”
