Optical Power Measurements
8.1 Mode for Optical Power Measurements
PM (PM1 or PM2)/TLTS
: use the OPM test mode to measure any incoming optical signal level
(CW, 270, 330, 1000, or 2000 Hz) between the wavelength range of 800 - 1700 nm. Then select
a calibrated wavelength that matches the incoming source wavelength.

8.2.1 Setting ZERO Level
Set the ZERO level before the first use of FX87 for broadband power
measurements. We also strongly advise to set the ZERO level before every new
batch of measurements, and after measurement conditions have changed.
To set the ZERO level:
1. Press the
|MODE|
button to enter the optical power measurement mode (PM);
2. Press
|F3|
(MORE), then press
|F1|
(ZERO). The
ZERO
notification will show briefly
