Measurement Units
Emonitor and the Enpac Ex support many different measurement units. The
measurement units that appear in the Enpac Ex are text that depend on:
• The type of measurement definition
• The units for the measurement definition
• The transducer specification used in the collection specification for the
measurement definition
The Enpac Ex can collect data for English units, Metric units, or Decibels. It
uses the units that you select in Emonitor. You can select units from a single
system (e.g. English g’s, in/sec, etc.), or you can mix units from different
systems (e.g. English g’s, in/sec and Metric m/s
2
, m/sec) in one list. The
Enpac Ex loads the exact text string from Emonitor. The signal detection type
(peak, rms, true peak, etc.) is appended to the units on the Enpac Ex screen.
IMPORTANT
Using the 0.36 Hz (21.6 CPM) low cutoff filter for
integrated measurements or the 0.18 Hz (10.8 CPM) low
cutoff filter for non-integrated measurements will always
cause the Enpac Ex to go into a long autorange mode.
Only use these filter settings when very low frequency data
is required.
