4.2.2 Data logger
The data logger feature is used to sample and record up to ten actual values at a
selectable interval. The datalogger can be run with Continuous mode Enabled, which will
continuously record samples until stopped by the user; or with Continuous mode Disabled,
which will trigger the datalog once without overwriting previous data.
Viewing and saving of the Datalogger is performed as follows:
1. With EnerVista MM300 Setup running and communications established, select the
Diagnostics > Datalog menu item to open the datalog setup window:
2. If Continuous mode is enabled, click on Stop to stop the datalog
3. Click on the Save to File button to save the datalog to the local PC. A new window will
appear requesting for file name and path.
4. One file is saved as a COMTRADE file, with the extension ‘CFG’. The other file is a DAT
file, required by the COMTRADE file for proper display of data.
5. To view a previously saved COMTRADE file, click the Open button and select the
corresponding COMTRADE file.
6. To view the datalog, click the Launch Viewer button. A detailed Datalog window will
appear as shown below.
