* This instrument performs a zero adjustment (auto-offset) when
the power is turned ON.
For low level measurement (-50 dBm or less), in order to cancel
out temperature changes and other effects, it is recommended to
power cycle the instrument before measurement to perform the
zero adjustment. The zero adjustment need not be performed
while shielded from light. The optical connector cap is designed
to protect the connector from dirt and collision, and does not
provide light shielding.

Remove the optical connector and attach the optical connector
