Unique function for accurate voltage and frequency measurements on adjustable speed motor drives and other electrically noisy equipment. Built-in thermometer conveniently allows you to take temperature readings without having to carry a separate instrument. Optional magnetic hanger for easy set-up and viewing while freeing your hands for other tasks. Large digit display with bright, two-level backlight makes the 80- Series V significantly easier to read than older models. Features: True-rms ac voltage and current for accurate measurements on non linear signals. Selectable filter for accurate voltage and frequency measurements on motor drives. 0.05 % dc accuracy. 6000 counts, 3-3/4 digits. 4-1/2 digit mode for precise measurements (20,000 counts). Measure up to 1000 V ac and dc. Measure up to 10 A, 20 A for up to 30 seconds. Built in thermometer lets you carry one less tool (TC probe included). Frequency to 200 kHz and % duty cycle.

Resistance, continuity and diode test. 10,000 µF capacitance range for components and motor caps. Min/Max-Average recording with Min/Max Alert to capture variations automatically. Peak capture to record transients as fast as 250 µs. Relative mode to remove test lead interference from low ohms measurements. Auto and manual ranging for maximum flexibility. Touch Hold to capture stable readings avoiding noisy signals. Large display digits and two-level bright white backlight for increased visibility. Analog bargraph for fast changing or unstable signals. Input Alert provides audible warning against wrong use of input jacks. Improved selectable sleep mode for long battery life.

Fluke 87-5 Review

First, even Fluke: Fluke 87-5 is the best quality meters. In fact, they are mostly available only feet better. This does not mean that there are no other very good brands (such as Agilent, Hioki), or the 2 tier brands (eg, EXTECH, Meterman not) in their place - IT. But Fluke meters generally offer the best combination of data, based on better and better protection (for you and the numerator). The trick is that you pay top dollar.

The 87 meters is very hard to use widely in this area. Counters 80 series, as the 70-series that preceded them, the reputation of pursuing its accuracy and decades. They are well protected and well shielded, sealed and covered stories of surviving Fluke meters, high voltages and currents, weather and many other challenges abound.

Details on the care and react style. Fluke 87-5 is sensitive. The continuity detection, for example, is extremely quick to the point where it is difficult not trigger so as to emit a beep when the test by touching the probes, no matter how fast and try to touch them briefly together. Compare that with other instruments and any response you dawn, how easy it is to an intermittent miss. The basic accuracy is very limited in the number 80 and the positions of over 1 or 2 in most areas. Compare this with many others, where there are often 4 or more, plus 87 can in a crowd of 20,000-mode are provided, and the relative mode can be used for greater precision and when you need it .

Finally, leads 80-Series offers a lifetime warranty. Since aggressive meters Amazon on these amounts, the premium on a counter below, say, the Fluke 117 (only guaranteed for 3 years) is low enough to be worth switching to a meter better.
