By pressing PLAY or PAUSE the user can move forward or backward
(respectively) through the logged error codes. The highlighted number
indicates which error code is currently on display (in the example
above, error code number 4 is displayed). If “0000” is displayed at all
positions, the error log is empty. Display of the logged errors is done
in a cyclic manner. The error code with the lowest highlighted number
is the most recent.
By pressing NEXT on the local keyboard, the user can proceed to the
next test.
See below for ERROR LOG information.
Error Bits
Reading the error bits is done in the Level ReadBits. The display during
the error bits readout looks as follows:
