routine calibration or maintenance. Note that any alternative Certifier Plus Flow Module may be
used with the .
All re-calibrated flow modules are returned from TSI
®
with a certificate of calibration and a summary of
performance before and after the calibration. A calibration consists of pressure calibrations over the
full range of pressures and flow calibration over the full range of flows. All calibration data is stored in
the flow modules. The interface module does not contain any factory calibration information.
