    2 Operational Theory Model 2010A Figure 2-1: Thermal Conductivity Cell Operating Principle If the thermal conductivities of the gases in the two chambers are different, the Wheatstone bridge circuit unbalances, causing a current to flow in its detector circuit. The amount of this current can be an indication of the amount of impurity in the sample gas, or even an indication of the type of gas, depending on the known properties of the reference and sample gases.

    (See Remote Calibration Protocol below.) Remote Calibration Protocol: To properly time the Digital Remote Cal Inputs to the Model 2010A Analyzer, the customer's controller must monitor the Cal Relay Contact. When the contact is OPEN, the analyzer is analyzing, the Remote Cal Inputs are being polled, and a zero or span command can be sent.

  • Page 30: Range Id Relays

    However, if you have the –C, -P, or -Q Internal valve option, which includes zero and span gas inputs, the 2010A automati- cally selects the zero, span and sample gas flow.
