Combining Measurement Definitions for a Location
You can use Emonitor to set up many different measurement definitions for
data collection at a location. These can include magnitude, spectrum, time
waveform, and numeric measurements. You can then select the measurement
definitions you want to load to the data collector by creating a list of those
measurement definitions. When you want to load the data collector, Emonitor
builds a load file containing the measurement definitions in the list.
Emonitor combines measurement definitions at each location to make data
collection more efficient. This allows you to collect two or more
measurements automatically, without having to start each measurement
separately. The rules for combining measurement definitions depend on

TIP
The "Voltage" transducer is for Volts AC. The "Voltage
DC" transducer is for Volts DC.
