RANGE* The range setting determines the maximum distance shown on the trace. Select the range that is
nearest to, but not less than, the distance to the event you want to study. If the tester does not
correctly identify the end event, run the OTDR test again using the next highest range.
Auto: the tester selects the maximum range that is valid with the RESOLUTION setting. If RESOLUTION

These ranges are not limited to the fixed ranges provided.
