Figure 2–38. Errors screen
If the PDM unit has encountered more than one status condition, pressing
the "B" button repeatedly allows viewing of all the error conditions that
occurred during the primary sample run.
The current screen number and number of screens is displayed in the lower
right corner. In this case, screen 1 of 2.
There are a number of status errors that may appear during a programmed
or primary sample run. A blinking 'E' in the upper right corner of the
display indicates that an error has been encountered. The blinking can be
stopped by navigating to the 'View Errors' screen. The 'E' will remain for
the duration of the sample run. If a new status error is flagged the 'E' will
start blinking again until the new error is viewed.
Below is a list of the status codes that can be encountered during a sample
run.
