Features of LOG
The Logging Option [order LOG] allows the 3030A to log data and store the log internally for later retrieval. Features of this option include:
- Ability to set the logging interval anywhere from once a second to once each 99 minutes.
- Ability to select which of 60 variables to include in the log.
- Ability to pause and resume logging so multiple setups or logs can be stored in the unit.
- With Extended Memory Option [MEM] ability to log 60 variables for 47 days at 15 minute intervals.
- With PC Control/Analysis Option [PCCA] ability to retrieve the log and graph it or import it into Excel.
The Importance of Logging
Simple monitoring of a circuit will tell what the average, maximum, and minimum values are, but will tell nothing about how they change over time. When you log, you record the average, maximum, and minimum values at regular intervals. This allows you to:
- graph averages over time
- identify when maximums and minimums occurred
- view how often and when extreme readings occurred.
In addition, graphical printouts of logs have much more impact in reports than simply reporting three summary measurements.
