Binding post side panel.
(2) The "BAT" position connects the metering circuit to the battery
circuits in the test stand. This permits the voltage condition of the batteries to
(3) The "EXT" position permits the voltmeter to measure DC voltage from
sources outside the test stand circuitry. In this position the metering circuit is
connected to the positive and negative DC voltmeter binding posts.
(4) In the "VAR DC SUPPLY" position the metering circuit is connected to
the negative and positive DC power supply binding posts (10, fig 7). Variable DC
voltage supplied by the test stand to a DC system under test can be monitored with
the switch in this position.
