When the measured field strength is below 5% of full scale for the range being
used, the under range indicator (
◄
) will appear and the display will flash on
and off. When possible, switch the range to permit a field strength reading which
does not trigger the under range indicator. If the field strength exceeds full scale,
the over range indicator ( ► ) appears and an alarm will sound. Select the next
appropriate range.
