Information

1-2. Your John Fluke Model 8050A is a portable bench- type Digital multimeter (DMM) with a 4-1 /2 digit liquid crystal display (LCD). The 8050A has all the following industry-standard features: » Voltage measurements from 10 μ to 1000V dcand 10 mV to 750V true-rms ac. • Current measurements from 10 nA to 2A dc and 10 μΑ to 2A true-rms ac. ® Resistance measurements from 10 mH to 20ΜΏ. The 8050A also has several special measurement features. These special features include the following: • Conductance measurements up to 100,000 Mil. • Voltage measurements in decibels, that can be referenced to 1 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, 10 microseconds. • Dual-slope integration a/d conversion to ensure noise-free measurements. • Long term calibration stability (1 year). 1-3. The 8050A is warranted for a period of one year upon shipment of the instrument to the original purchaser. Conditions of the warranty are given at the front of this manual. The 8050A is typically powered from ac line voltages but may be powered by the optional rechargeable battery.
