Transfer Calibration
NOTE: Transfer calibration does not require an external voltmeter. It can be performed independently of the full calibration or the mainframe reference calibration. However, transfer calibration requires a 24 volt dc source to be connected to the power bus.
During transfer calibration, each individual channel is sequentially connected to the internal reference and gain and offset corrections are calculated and stored in
Mainframe Reference Calibration
Mainframe reference calibration (also referred to as standard calibration) calibrates the internal references in the Agilent MCCD mainframe. It requires an external voltmeter to be connected to Serial Port A of the Agilent MCCD. Refer to Figure
