Fluke 87-5 (87V) True RMS Digital MultimeterNew features for maximum productivity! 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. Access door for fast battery changes without breaking the calibration seal. "Classic" design with new removable holster with built in test lead and probe storage. Lifetime warranty.
