11.5.2. View Channel Data
The View Channel Data menu will display the data that is currently being read from the analog to
digital convertor (A/D). This menu can be used as a diagnostic tool to verify that all of the channels
are able to receive data from the A/D. The information that is present can help determine if there
is a fault with one or more of the channels or if there is an offset in the data.
The information available for each of the four channels (transverse, vertical, longitudinal and
microphone. Channels 1, 2, 3, 4 respectively) is:
1) The Current value. This is refreshed once every second.
2) The Minimum value is the lowest value that has been read up to and including the current
sample. This value is reset to zero once every minute.
3) The Maximum value is the highest value that has been read up to and including the current
sample. This value is reset to zero once every minute.
4) The Average value is the average of all of the one second samples that has been read up to
and including the current sample. This value is reset to zero once every minute.
5) The Max Diff (maximum difference) is the greatest difference between the Minimum and
Maximum values that have been read. This value is refreshed every second and reset to
zero once every minute.
The Max Diff value is calculated by determining the difference between the minimum and
maximum values. For example the display screen below has a minimum value of -6 and a
maximum value of +11 on channel one. Therefore the max Diff is reported as 17.
Assuming the signals are relative centered, the minimum and maximum values are the same, the
average should be zero or very close. If the absolute average value is greater than five counts
without any vibration or overpressure, it is recommended that the Remove Offset command be
performed.
