Calibration Information
A daily system calibration must be performed each day the Atomlab 960 is to be used. Separate
calibrations are performed for the probe and well. The system keeps an internal listing of its
last calibration date and prompts when calibration is needed. The system will not allow
measurement procedures to commence until the calibration has been performed.
Calibration is performed automatically from the Quality Assurance Daily Calibration screen. The
Select Detector screen advises when the last high voltage and calibration were performed for
your detectors. It also checks to ensure that the MCA, detector and CPU are connected and
communicating with each other. This is noted in the on-line column and is set to display or not
in the system setup procedure.
