Replacing the Fuses

To avoid electric shock, disconnect the test leads from any source of voltage
before removing the meter cover.
• Disconnect the test leads from the meter.
• Remove the protective rubber holster.
• Remove the battery cover (two "B" screws) and the battery.
• Remove the six "A" screws securing the rear cover.
• Gently remove the old fuse and install the new fuse into the holder.
• Always use a fuse of the proper size and value (0.5A/1000V fast blow for the 500mA range,
10A/1000V fast blow for the 20A range
• Replace and secure the rear cover, battery and battery cover.
To avoid electric shock, do not operate your meter until the fuse cover is in
place and fastened securely.
