Monitoring only peak
and bottom amounts
of received light
[P2] Hold display The peak (highest) value and bottom (lowest) value of the
received light amounts that have been measured are saved
and displayed.
With reference to the peak and bottom values, manual
adjustment of the threshold can be made at the correct
values.

Stretching the
received light amount
to check the margin of
the set threshold
[P9] Stretch mode A stretched (magnified) amount of received light is
displayed.
In situations such as when the value of the received light
amount is low, this function makes it easy to check the
margin of the received light amount in relation to the set
threshold.
