Explanation
Switches the measuring range between “AUTO range” and “MANUAL range.”
Two modes are provided for the measuring range of the optical sensor; one is
“AUTO range” which automatically changes the measuring range depending on
the input optical level, and the other is “MANUAL range” which measures in an
arbitrary specified fixed range.
“AUTO range” is set when the parameter is “ON” or “1”, and “MANUAL range”
is set when it is “OFF” or “0.”
When the “MANUAL range” mode is used, specify the range using “SENSe<n>:
POWer:RANGe[:UPPer].”
POINT
It is recommended that measurements be carried out in
the “AUTO range” mode, when the optical level to be
measured is unknown or varies significantly (by 10 dB
or higher). On the other hand, when the optical level to
be measured is known and I-L measurements are to be
performed, it is recommended that measurements be
made in the “MANUAL range” mode by fixing the mea-
suring range.
