The connector panel (Item 1) provides connectors for the external (DUT) Type-K
thermocouple and the computer interface cables. The alumel (-) leg of the thermocouple plug
is slightly smaller than the chromel (+) leg and must be inserted in the top of the receptacle.
The system is equipped with an automatic condensate drain (Item 5) which will drain off any
water or oil trapped by the inlet pre-filters that are present in the supplied air stream. It will
automatically drain from the unit at the right rear corner, beneath the machine. A collection
