Fuse Replacement
The current input terminals of your multimeter are fuse
protected. The fuses are located next to the battery
compartment.
• The
µA mA terminal is protected by a 10 × 35 mm
440 mA/1000 V 30 kA fast- acting fuse (Fuse 1).
• The
A terminal is protected by a 10 × 38 mm
11 A/1000 V 30 kA fast- acting fuse (Fuse 2).
If you are certain that the fuse is faulty, replace it with one
of the same size and rating.
1 Open the battery cover. Lift the tilt stand and loosen
screws with a suitable Phillips screwdriver and remove
the battery cover.
2 Locate the faulty fuse. Fuse 1 (see Figure 2- 3) is located
to the right of batteries, and Fuse 2 (see Figure 2- 4) is
located at the bottom of the batteries. See Figure 2- 5 for
the specific location, size, and ratings of Fuse 1 and 2.
Gently remove the defective fuse by prying one end of the
fuse with a flathead screwdriver and removing it out of
the fuse bracket. Replace a new fuse of the same size and
rating into the center of the fuse holder.
3 Close the batter cover. Place the battery cover back in its
original position and tighten the screws.
NOTE
No recalibration is required after replacing the fuse.
CAUTION
Before you proceed with the fuse replacement, remove all cable
connections to the terminals and ensure that the rotary switch is at the
OFF position.
