Value
Specify the engineering value associated with the transducer when rezeroed.
NOTE
There is a limitation on rezeroing low level signal conditioners when using high level
input levels. If the rezero results in the situation where the full-scale values exceed the
voltage limits of the signal conditioner, a calibration error occurs before the test run
starts. For example, suppose the full-scale values are ±10.0 volts for a signal
conditioner with a range of ±10.2 volts. If the rezero offset is 0.5 volts, the eDAQ
lite
attempts to set limits of -9.5 and +10.5 volts causing a calibration error to occur
because the +10.5 volt limit cannot be achieved.
NOTE
For quadrature decoder channels, the eDAQ
lite
resets the internal counter value to
zero before rezeroing.
6.1.7 Display Control
Scope
Select the Scope button to open a scope plot display for the input channel. Note that
the Scope Plot is similar to an analog oscilloscope except that the display is not
updated until the eDAQ
lite
acquires all of the data samples and transferred them to
the host computer, which creates a delay in the data presentation. For more
information on the scope plot, see “Scope Plot” on page 77.
DVM
Select the DVM button to open a DVM display of the input channel. In this display
mode, the transducer signals are repetitively sampled and displayed in a digital format.
For more information on the DVM display, see “DVM” on page 75.
6.2 Digital Input Channels
6.2.1 Digital Input
Add a digital input channel to any bit on an ELDIO layer. The eDAQ
lite
uses standard
switching logic to determine the boolean state of the channels. For more information
on ELDIO digital inputs, see “ELDIO Digital Input/Output” on page 92.
NOTE
The last four bits (9-12) of the ELDIO are dedicated to wide range input channels.
Output Data Type
The output data type for digital inputs is always 8-bit unsigned (logical).
