isolation channels. Multiple channel operation should only be performed by experienced
test system engineers.
WARNING
NOTE
Careless multiple channel operation could create an electric shock haz-
ard that could result in severe injury or death. Improper operation can
also cause damage to the switching modules and external circuitry.
Multiple channel operation should be restricted to experienced test
engineers who recognize the dangers associated with multiple channel
closures.
Multiple channel operation cannot be used to perform thermocouple tempera-
ture measurements using the internal or external reference junction. The simu-
lated reference junction will instead be used and the integrity of the temperature
reading will be questionable ("ERR" annunciator turns on). See
measurements," page 3-25, for details.
