Specific Applications--Noisy Resistance
Measurements
Most digital multimeters are so sensitive they can not
tolerate as much as 50 mV of the line noise while making
resistance measurement; their digital displays become
unreadable due to the line noise. On the other hand,
because of the mechanical inertia of the analog needle,
the noise alternately pulls the needle to the left and then
to the right, averaging out any movement and leaving a
fairly stable resistance reading.
The Fluke 27 resistance measurement circuit is designed
to tolerate ac noise far better than the usual DMM.
Readable 2-kilohm readings can be obtained even in the
presence of 1 V ac noise. Readings of 1 megohm may be
obtained with up to 2 V ac noise. The noise appears as
about 50 counts of change and an oscillating bar graph.

Operator Maintenance
To avoid possible electric shock or personal
injury:
To prevent arc blast and resulting injury,
install only the EXACT replacement fuse
listed in the Maintenance section.
Do not allow water to get inside the case.
Remove any input signals prior to
removing test leads and opening case.
When servicing the meter, use only
specified replacement parts.
Before closing battery door, make sure
fuse cover is in place.
Make sure the battery door is closed and
latched before you operate the meter.
