c.
Either 12 or 24 volts is selected as an output from
the source as shown in Figure 1-3 by the positioning of the
RESISTANCE AND VOLTAGE FUNCTION SWITCH. The
precise values shown on the VOLTMETER dial are
obtained
by
utilizing
the
COARSE
AND
FINE
RHEOSTATS, which provide compensation for varying
conditions of the 45 volt battery source. Stepped precision
resistance values are selected for output by setting the
TEMPERATURE SELECTOR SWITCH pointer to a
particular temperature indicated on the dial, while matching
the bulb resistance to that of the resistance thermometer
under test.
