Setting Up Measurements

The figures in a typical measurement setup in the following sections refer to
making selections in these dialogs. For example, a table for STD (HZ) 2000
collection specification would look like this.

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 2500 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, choose 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.
