122 Frequently Asked Questions and Answers
How do I clear data from lists after unloading?
The Enpac Ex allows you to clear data from a list in the Enpac Ex after
unloading it to your Emonitor database. This enables you to collect the list
again as needed. Simply select the Clear list on unload check box in the
Unload Options dialog box. Another method is to use the Clear data from
list function in the Data Collector Functions dialog box.
How do I print reports after unloading data?
Emonitor allows you to print reports to a printer immediately after unloading
the data to your Emonitor database. This enables you to view the results of the
data just unloaded. Select the Print reports check box in the Unload Options
dialog box and highlight the desired reports.
Analyzing Data in Emonitor Why does the magnitude reading not correspond to the
calculated overall value?
Emonitor can calculate an overall value from a spectrum measurement. Under
some conditions, this value may not be the same as the magnitude
measurement for the same location. The common use for this are:
• The measurement filter is not the same for the magnitude and the
spectrum measurement definitions. In this case the two measurement
definitions are measuring different frequency ranges.
• The magnitude readings taken by the Enpac Ex are broadband readings
and ar not based on the spectrum data.
