5. MAINTENANCE

5.1 Replacing the mains fuse

If the fuse blown, the display will be off and the power supply will not operate. The
fuse should not normally blow unless a problem has developed in the unit. Try to
determine and correct cause of the blown fuse, then replace only with a fuse of the
correct rating and type. The fuse is located on the rear panel (see Fig. 2).
For continued fire protection. Replace with 250V fuse of the specified type and
rating, and disconnect the power cord before replacing fuse.
For 230 V AC: Type IEC127 5 x 20 mm. 250 V Time-lag (T) 3.15 A
For 115 V AC: Type IEC127 5 x 20 mm. 250 V Time-lag (T) 6.3 A
AVOIDING THESE DIRECTIONS COULD DAMAGE THE EQUIPMENT
Make sure that only the fuses of the given types and nominal current ratings are
used as replacements. The use of repaired fuses or the bridging of fuse holders is not
permitted. A small flat-bladed screwdriver is required to change the AC fuse. Carefully
lever up the cover in the AC power socket and withdraw it. Remove the defective fuse
and replace it with an intact one of the same type and nominal current rating. Afterwards
replace the fuse cover.
The measuring instrument is operated only when the case is securely closed and
screwed up.

5.2 Cleaning Recommendations

Make sure that the device is disconnected when cleaning the casing.
Do not use aromatic hydrocarbons or chlorinated solvents for cleaning. These
products can attack the materials used in the casing.
