Attaching the PON meter to a different point in the PON network will require a different set of thresholds for power measurements of
PON wavelengths. It is important to set thresholds in the PON meter so that it can show PASS/FAIL/WARNING results.
Up to 10 different threshold sets can be configured in the PON -2M PON power
meter.
SET THRESHOLDS
Press the
THRESHOLD
button to enter the menu for setting PON thresholds.
DISPLAY
1
Threshold Set Number
Value: 1 - 10
2
Wavelength
1310, 1490, or 1550nm
3
Upper FAIL Threshold
Power levels above this value will be
reported as FAIL
4
Warning Threshold
Power levels below this value will be reported as a warning (WRNG)
5
Lower FAIL Threshold
Power levels below this value will be reported as FAIL

When finished setting thresholds, ensure that the desired threshold set number is selected, then press
THRESHOLD
twice
to exit.
After exiting the SET THRESHOLD screen, do NOT change any of the calibration values on the “Calibration”
screen that appears. Changing these calibration values will cause the device to lose its NIST calibration.
Press THRESHOLD to exit the “Calibration” screen.
