Description
Information
                                    1-2. Your John Fluke Model 8020B is a pocket-size digital
multimeter that is ideally suited for application in the
field, lab, shop or home. Some of the features of your
instrument are:
• All VOM functions plus conductance and continuity (8 in
all) are included as standard.
DC Voltage - 100 μν to 1000V AC Voltage - 100 μν to 750V DC
Current - 1 μΑ to 2000 mA AC Current - 1 μΑ to 2000 mA
Resistance - 0.1 il - 20 ΜΩ Diode Test
Conductance - 0.1 ns to 200 ns and .001 ms to 2 ms (S =
siemens = 1/Ω). Continuity - Provides an immediate audible
indication when continuity is detected.
• CONDUCTANCE - A new multimeter function that allows fast,
accurate, noise free resistance measurements up to 10,000 ΜΩ.
• A high contrast 3-1/2 digit liquid crystal display that
can be easily read from across the room. No more worries
about bent needles, parallax, etc.
• Each range has:
Full auto-polarity operation
Overrange indication
Effective protection from overloads
• Dual slope integration measurement technique to ensure
noise-free measurements.
• Long term calibration stability - 2 years. Easy
calibration - few adjustments.
• Lightweight - 369 grams (13 ounces).
• Up to 200 hours of continuous operation can be expected
from a single, inexpensive, 9V, alkaline battery (transistor
radio/calculator type).
• Low battery voltage automatically detected and displayed.
• Line operation is possible using a Model A81 Battery
Eliminator (see Section 6, Accessories).
e Protected test leads - finger guards on the probes and
shrouded contacts on the connectors discourage accidental
contact with circuit voltages.
• A full line of accessories that extend the range and scope
of your instrument.
