Keithley 7057A
Scanner Card
Description
This Scanner Card, provides a higher change in reference output for improved cold junction sensitivity.
Formulae for converting the voltage outputs of all of the most popular thermocouple types are included in the manual.
The contact potential of <1µV per channel translates to <0.025ºC error for precision measurements on type K thermocouples.
Key Points
Cold junction compensated
2 pole Form A
<1µV of switch contact potential
Permits monitoring of up to nine thermocouples or other transducers
The nine signal channels use a guarded 2 pole configuration
Specifications
