D-1 DESCRIPTION
The Rosemount MPS 3000 Multiprobe Calibra- tion Gas Sequencer provides automatic calibra- tion gas sequencing for up to four probes. The MPS routes calibration gas to the selected probe under control of the CRE, IFT, or digital electronics package. The electronics package can be preprogrammed by the user for auto- matic periodic recalibration, or manually initiated calibration through the keypad on the front of the electronics package. The calibration pa- rameters held in the electronics package can be selected to automatically update after each calibration.
The MPS is housed in a NEMA 4X (IP56) non- hazardous enclosure, Figure
NOTE
A single multichannel MPS cannot be shared among a number of CRE electronics.
