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.
