Fuse 2: Glass fuse 10A, 250V, fast type, 5x20mm.
To avoid electrical shock or arc blast, or personal injury or
damage to the Meter, use specified fuses ONLY in
accordance with the following procedure.
To replace the Meter’s fuse:
Press the POWER to turn the Meter off and remove all
connections from the terminals.
Remove the screw from the battery compartment, and
separate the battery compartment from the case bottom.
Remove the 2 rubber feet and 2 screws from the case bottom,
and separate the case top from the case bottom.
Remove the fuse by gently prying one end loose, then take
out the fuse from its bracket.
Install ONLY replacement fuses with the identical type and
specification as follows and make sure the fuse is fixed
firmly in the bracket.
