Tilt Stand Adjustment; Fuse Test; Fuse Replacement - Fluke 27/FM Operator's Manual

Fuse Test and Replacement
Clean the case with a damp cloth and detergent; do not use abrasives or
solvents.
Have the meter calibrated by a qualified technician once a year to
ensure specified performance.
Tilt Stand Adjustment
To use the tilt stand as a handle, lift the stand slightly (about 1 inch or
2.5 cm), pull the ends out, and insert the ends in the alternate set of holes.
Fuse Test
Use the following procedure to test internal fuses:
1. Turn the function selector switch to the
n position.
2. Connect a test lead from the V
n 44- input terminal to the A input
terminal.
3. The display should indicate between 0.1 ohm and 0.3 ohm. This tests
F3 (15A, 600V fast).
4. Move one end of the test lead from the A input terminal to the
mA/uA input terminal.
5.
The display should indicate between 4.5 ohms and 6.5 ohms. This
tests F1 (1A, 600V fast).
6.
If either of the above display indications is OL (overload),
replace the appropriate fuse.
