Testing DUT 1
Test procedure:
NOTES The following test procedure assumes a Model 7700 switching module installed
in slot 1 of the mainframe.
The procedure assumes that the instrument is operating in the continuous
measurement (triggering) mode (see “Defaults and user setups,” page 1-22).
Do not use the following procedure to perform thermocouple temperature
measurements with the INTernal or EXTernal reference junction selected. The
SIMulated reference junction will instead be used resulting in invalid readings.
The “ERR” annunciator will turn on to indicate that the integrity of the
temperature reading is questionable.
