The 7014 card with the 7001 or 7002 mainframe is designed to be used with the Keithley Model 2001 DMM. The 2001 uses the reference junction output from the 7014 to display properly compensated and linearized temperature readings from the thermocouples.
The 7014 is an excellent general purpose multiplexer that can be used for a wide variety of signals in addition to thermocouples. The 1μV–110V and 100pA–1A signal range of the card makes it well suited for both low and high level signals.
The 7014 has four independent banks of 2-pole multiplexer switching—three 1´10 and one 1´9 (the 10th channel on this bank is the reference junction sensor) configurations. These four banks can be combined for a wide variety of switching configurations. Each of the four multiplexer outputs can be connected to the 7001 and 7002 analog backplane through removable jumpers for even greater flexibility.
Thermocouple signals can be mixed with other measurement signals such as voltage, resistance, and current. Mixed signals can be switched on adjacent channels within the same bank, or separate banks can be allocated for different signal types.
This card will automatically configure the 7001 and 7002 mainframes.
