- Notes
-
The Weston model 904 AC Ammeter has terminals for 0.5, 1, 2, and 5 amperes. The meter is specified for line frequencies of 25 to 500 Cycles (Hertz). The approximate impedance figures for each range at 60 Hz are listed directly on the meter face in a hand-drawn lettering. Note that Weston used the same model number for an AC Voltmeter 904 of similar outward design, not unusual for Weston model numbers for meters.
