Logger
Introduction
Logger is a function that gives you the possibility to log multiple readings with high
resolution. The readings are observed during adjustable time intervals. At the end of the
interval the min, max, and average values of all readings are stored and the next
observation interval starts. This process continues for the Duration of the observation
period.
The Analyzer has as a default a predefined set of readings that is used for logging. This
set can be customized to your own set of readings. Via the Setup Readings from the
logger start menu you can Add or Remove readings to be logged.
You start the Logging function from the Start menu that allows you to select the Interval
time (0.25 s – 2 Hr.), the readings to be logged, the maximum duration of the logging
(1 Hr. – Max) and Immediate or Timed start of logging.
Readings are displayed in a Meter screen, a Trend screen, and an Events Table.
