Service and Calibration
The SEM5000 should be regularly serviced. QED recommends that the instrument is
calibrated on an annual basis.
NOTE: The next calibration date can be seen during the warm up sequence after

charging connector.
The hydrophobic internal filter should be checked periodically, (typically this will be
weekly during periods of heavy use).
