When you press Graph/TEXT ( ) after performing a scan with the
USER SCAN button, you can see a user scan graph screen such as the
following.
OFFSET (VOLATILE)
The OFFSET function displays the
addition of set up dBm value and the
optic power value on the screen.
The user can increase reliability and
continuously maintain the measuring
instrument's own features and settings
by synchronizing the output value with
other measuring instruments using the
calibration function for each channel.
Note: As this value is saved in the volatile memory, it becomes zero after booting
and is not remembered if you turn the power off after set up.
