Setting Up Measurements Chapter 2
The Enpac 2500 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 (for example, English g, in/sec, etc.), or you can mix units from different
systems (for example, English gs, in/sec and Metric m/s
2
, m/sec) in one list. The
Enpac 2500 loads the exact text string from Emonitor. The signal detection type
(peak, rms, true peak, etc.) is appended to the units on the Enpac 2500 screen.
Setting Up Collection
Specifications Measurement definitions are controlled in part by the collection specification
(Setup > Collection). You select the collection specification when you set up the
measurement definition. You can create new collection specifications based on
your specific measurement by choosing Setup > Collection.
