1A or 2A fuse replacement is necessary when there is no meter deflection on any
of the DC VOLTS, AC VOLTS or OHMS ranges, but the DC AMPS range operates
properly.
c.
NOTE: A spare fuse is located in a cavity next to the fuse clip.
When maintenance other than battery and 1 ampere fuse replacement is required,
remove the Instrument from its case. Proceed as follows:

c.
A 1 Amp 250 Volt quick-acting and 2 Amp high voltage, high interruption capacity
fuse is connected in series with the input circuit an additional protection to the
VOM against excessive energy fault current, such as a power line overload.
It is important to replace the 1 Amp fuse with Littlefuse Type 312001 only to pre-
vent the 2 Amp high interruption capacity fuse from opening on nominally high
overload.
If the Instrument fails to indicate, the 1 Amp or the 2 Amp fuses may be burned out.
(Refer to Paragraph 5.2 for fuse replacement.) A 1 Amp spare fuse is furnished
with each Instrument. (Both 1 Amp fuses are located in the battery and fuse com-
partment.) The 2 Amp fuse is located on the instrument panel under the printed
circuit board.
a. Immediately clean all spilled materials from the Instrument and wipe dry. If
b. When the Instrument is not in use, rotate the range selector switch to the
c. Whenever possible, avoid exposure or usage in areas which are subject to
To replace the 9V battery
1.withdraw old battery and mating connector from the compartment.
2. Remove the connector from the old battery and connect it to new battery.
3. Put the new battery into the compartment.
4. Place the connector leads so they rest between the cavity walls and clear
the fuse terminals. Place the extended leads between the battery holder and
top wall of the case.
To Replace the 1 Amp Fuse:
1. Pull the defective fuse from its retaining spring clips (fuse holder).
2. Snap in the replacement fuse and reinstall cover.
Case Removal
Place the Instrument face down on a soft padded surface.
Remove the battery and fuse compartment cover, located at the top rear of
the 260 case (paragraph 5.2). Unscrew the four screws located at the four
corners of the case.
Lift the case off the Instrument and set it aside. Maintenance now can be
performed on the Instrument.

and then gently push the + side of the battery into place.
