  • Annotazioni
  • The Fluke 887AB AC-DC Differential Voltmeter provides conventional or differential measurements of ac voltages from 1 mV to 1100 V and dc voltages from 0 uV to 1100 V.

    Voltage Ranges 1,10,100,1000 Vac and Vdc.

    Null Ranges 100uV through 100 V end scale ac and dc in seven ranges.

    DC input resistance, infinite at null from 0 to +- 11Vdc,10 megaohms above.

    DC accuracy +- 0.0025% of input + 0.0001% of range +5uV from 0 to 1100 Vdc at nominal calibration temperature.

    AC accuracy +-0.05% of input +0.0025% of range from 1 mV to 500V and frequency up to 5 kHz, with reduced accuracy above 500V and/or at higher frequencies.

    Conventional (TVM) measurements are made with an accuracy of +/- 3% of the selected range to initially determine the magnitude of the measured voltage.The differential (NULL) mode is then used with above accuracy  to determine the exact value of the measured voltage,using the front panel 5 readout dials.

    The model 887AB can operate from line or internal rechargeable battery (3 Nickel cadmium Battery packs are installed).

    Fluke 887A has the same specifications, but is without battery operation.
