52 Setting Up Measurements
Temperature measurements
• Set up a temperature measurement definition by setting Data Type to
"Numeric" and Units to "RPM," "CPM," or "deg. C."
• Set up the temperature transducer in the Transducer Calibration
dialog box with Input type set to "DC Coupled" and Units to "deg. F"
or "deg. C." Make sure you enter the Calibration value that converts
the voltage to a temperature.
• Set up the collection specification to include a Signal detection of
"RMS."
Magnitude alarms in the Enpac Ex
You can use magnitude alarms with numeric measurements.
• The Enpac Ex supports above, below, in window, and out of window
magnitude alarms with numeric measurements.
• You must set Trigger to "Yes" for any alarms you want to appear in the
Enpac Ex during data collection.
• For more on how Emonitor combines alarms before sending them to
the Enpac Ex, see Alarms and the Data Collector on page 60.
Typical numeric measurement definitions
Figure 3.10 shows the setup for typical numeric measurement definitions.
Note that the first two measurements are numeric (DC) voltage measurements,
and the third is a numeric manual entry measurement.
