Your John Fluke Model 8050A is a portable bench-
type digital multimeter
(D
MM) with a 4-1/2 digit liquid
crystal display (LCD). The 8050A has all the following
industry-standard features:
•
Voltage measurements from
10
µV
to
IOOOV
de and
IO
mV
to 750V true-rms
ac.
• Current measurements from I 0 nA to
2A
de and I 0
µA
to
2A
true-rms ac.
• Resistance measurements from
IO
mil
to 20MO.
The 8050A also has several special measurement features.
These special features include the following:
•
•
•
•
Conductance measurements up to 100,000 MO .
Voltage measurements
in
decibels, that can be
referenced to I
of
16
user selected reference
impedances.
Resistance ranges that supply enough voltage to
turn
on a
PN
junction
to allow diodes
and
transistors to be tested.
The ability to store any input signal as an offset or
relative reference value.
•
•
•
Automatic polarity indication
and
overrange
indication.
Protection from overloads and protection from
transients
of
up to 6 kV,
IO
microseconds.
Dual-slope integration
a/
d conversion to ensure
noise-free measurements .
• Long term calibration stability (I year).
