Setting Up Measurements 41
The table for the transducer specification in the STD (Hz) 2000 collection
specification would look like this.
Measurement Input Types
The input type is part of the transducer specification (Setup > Calibration).
The transducer is part of the collection specification (Setup > Collection).
You select the collection specification when you set up the measurement
definition.
Emonitor and the Enpac Ex support the following input types.
• ICP Accel - Use for ICP accelerometers requiring current from a power
supply.
• AC Coupled - Use for AC voltage measurements and non-ICP
accelerometers.
• DC Coupled - Use for DC voltage measurements. This includes
numeric (process) measurements taken from a DC voltage output.
• Manual Entry - Use for numeric (process) measurements where you
enter the value for the measurement with the data collector keyboard.
To specify an input type, select Setup > Calibration, then select the correct
Enpac from the Collector list. You can then assign Input types, Calibration,
and appropriate Units to the transducer you wish to use.
