Setting Measurement Range
To set the measurement range,
1. If necessary, select the desired channel (PM-1620).
2. Press Range until the required measurement range marker is shown at
the top of the display for the matching channel. The table shown below
displays the permitted manual ranges when the currently selected
measurement unit is dB or dBm. The power range values displayed are
typical at 1310 nm.
Note: Select a manual range in power measurement mode when the input signal
has unstable or modulated variations. This prevents !!!!!!! from being
displayed upon constantly changing gain scales.
