actual input voltage and perform the following steps.
1. Turn off the instrument, and then disconnect the instrument from the power
source. Remove the power cord.
2. Insert a slotted screwdriver into the slot of the fuse holder to pry it out, as
shown in Figure 1-7.

3. Take out the fuse and replace it according to the fuse rating (refer to the "Fuse
Rating" on the rear panel of the instrument or Table 1-2).
4. Mount the fuse holder (pay attention to its direction when mounting it).
WARNING
To avoid personal injuries, turn off the instrument and cut off the power
supply before replacing the fuse; to avoid electric shock or fire disaster,
before connecting to the AC power, select the voltage specification that
matches the actual input voltage and replace a proper fuse that
conforms to the voltage specification.
