NOTE
To supply power greater than 400 milliwatts to a single transducer, define multiple
channels and tie their power sources together. All the channels used for a single
transducer must have the same voltage settings.
6.4 SMART Module Input Channels
Add a SMART module channel to any ELHLS connector with an installed SMART
module. Complete the parameters for the ELHLS parent channel as well as the
SMART module specific parameters. Configure the SMART module parameters by
selecting the configure option in the SMART module section of the ELHLS channel
setup window (on page two). For more information on SMART modules, see “SMART
Modules” on page 101.
Using SMART Utilities
Access the SMART utilities in the TCE transducer setup window. Highlight a SMART channel or a set of SMART channels
and select SMART Utils. TCE offers the following three options.
•
Program
—Serially program all selected SMART modules with the transducer channel definition that currently exists
and with any added pass through keyword value entries.
•
Blank
—Erase the selected SMART modules, restoring the user-data areas to their original blanked states.
•
LED Locate
—Repetitively toggle the LEDs of the selected SMART modules indicating the physical location of the
selected SMART modules. This function must be manually aborted.
6.4.1 SMSTRB4 (Strain SMART Module)
NOTE
The parameters for the SMSTRB4 are integral to the channel calibration. To edit any
of these parameters, first delete the existing calibration.
Excitation Range
The excitation range setting determines the monopolar excitation voltage applied
across the bridge. Select either 5- or 10-volt excitation for nominal bridge resistances
of 350 ohms and greater. For smaller bridge resistances, only the 5-volt excitation
range is available.
The signal input levels for SMSTRB4 transducers are limited by the excitation range
selection and the nominal gain which is determined by the calibration curve and not
directly configurable. For a 5-volt excitation range, the inputs are limited to ±180
