38 Setting Up Measurements
RSS Overall
The Enpac Ex allows you to take a digital overall measurement, instead of
analog. This set up makes measurement collection faster. Be aware that this
Root Sum Squares (RSS) overall value is not as complete because it does not
include the power in the signal from below the first spectral bin or above the
highest spectral bin. Please note that the RSS overall values may not trend well
with analog overall measurements.
To use the RSS filter, you must create a Band Filter in Emonitor. Select
Setup > Band Filter and click New. Then select RSS (digital) as the filter
type.
EXAMPLE
Emonitor uses the 5.30 Hz (318 CPM) filter for an
integrated measurement. It uses the 2.67 Hz (160.2 CPM)
filter for a non-integrated measurement.
IMPORTANT
The available filters in Emonitor depend on the data
collectors you select as active data collectors using Tools >
Set Active Collectors. If you have two or more active data
collectors, you may not see all the selections available for
the Enpac. If you have no active data collectors, you see all
the selections for every data collector, not just the
selections for the Enpac.
