Máy phát điện áp và dòng chuẩn FLuke 707

Tính năng Máy phát điện áp và dòng chuẩn Fluke 707

  • Large display and simple, quick-click interface for easy one-handed operation.
  • Simultaneous mA and % readout for quick, easy interpretation of readings.
  • mA accuracy of 0.015%, superior to other loop calibrators in this price range.
  • 1 µA resolution for mA source, simulate and measure.
  • Push button 25% steps for fast, easy linearity checks.
  • 0-100% “span check” for fast confirmation of zero and span.
  • Selectable slow ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop functional tests.
  • 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM.
  • Measures V dc to 28 V.
  • Single 9V battery that is easily changed without braking calibration seal
  • 0 – 20 mA or 4 – 20 mA default start up modes.
  • Innovative output adjustment dial with 1 µA and 100 resolution.
  • HART ™ mode connects 250 Ω resistor in series with 24 V loop for compatibility with HART communicators.
