This program is used for accurate steady state measurements, but also has PPM ballistics. Zero is referenced to Full Scale Digital, although this can be modified with the calibration adjustment to provide some headroom as required. If you need to run multiple meters for monitoring more than one source, there is a Multi-Channel Level Meter for up to 24 channels.
