Figure 1-21. John Fluke, Model 8922A/AA, True Rms Voltmeter.
John Fluke, Model 8922A/AA, True Rms Voltmeter, offers low-frequency capabilities in the 2 Hz to 11 MHz bandwidth and
a switchable 200 kHz low pass filter which eliminates unwanted high-frequency noise from the measured signal.
Figure 1-22. John Fluke, Model 887AB/AN, Differential Voltmeter.
John Fluke, Model 887AB/AN, Differential Voltmeter (fig. 1-22) is capable of being used as a conventional voltmeter for
rapid determination of voltages from 0 to 1100 V dc and from 0.001 to 1100 V ac; as a differential voltmeter for precise
measurement of dc voltages from 0 to 1100 V; as an accurate ac voltmeter for measurement of ac voltages from 0.001 to
11,000 megohms. It is rack-mounted in the standard 19-inch rack by means of rack adapter kit 881A-102.
