Note: The reading on the voltmeter should read null. 0.000 mV. Adjusting
the U.U.T. to any temperature and adjusting the Temperature Simulator to
the same temperature should result in a null, or 0.000 mV on the volt-
meter.
11. Disconnect the cables from the equipment and UUT and reconfigure the set-up
per figure 12.
