It is preferable to use the same type of connector at both ends of the
fiber being tested, to ensure the same connection conditions for
measuring P1 and P2.
Accuracy of measurements

perform a preliminary calibration without the fiber under test to elim-
inate the losses due to connections as far as this is possible. To do
this, use the «Reference Value» function.
