Calibrating the Meter

Caution

Devices with malfunctioning lasers must be returned to the manufacturer for calibration.

Annual calibration of the meter by JDS Uniphase is recommended. This section outlines how to do periodic adjustments to ensure the accuracy of backreflection, loss, and power measurements. Use only the calibrated jumper for all calibration procedures.
