Operation

The CEL-553 real time analyzer uses the concept of 'Runs' and 'Records' to make measurements where the operator is in complete command of the data capture. Up to 999 separate runs can be stored in the instrument memory and each run can save up to 9999 individual measurements. A run can then represent a measurement around a particular machine with the records representing the individual measurement positions associated with that machine. The run concept logically groups the individual measurements together for easy comparison when recalled from memory or downloaded to a PC.
