1. Summary
PON Power Meter is specially designed for PON network
construction and maintenance which can be connected
between OLT and ONT. The voice, data, video signal
(1310nm/1490nm/1550nm) online can be measured
synchronously and optical power value can be displayed
with this meter. It has special burst mode measurement
function and you can process accurate burst optical power
measurement to upstream PON signal of 1310nm. You can
process pass/fail analysis conveniently through multiple
users’ adjustable threshold of every wavelength. It adopts
32 digits CPU with low power consumption, so the
functions are more powerful and rapid. More conveniently
measurement for field and equipment site owes to friendly
operation interface. It’s a useful site test tool for the
engineers of PON network and maintenance operators.
2. Main Features

5. Operation Instruction
5.1 ON/OFF
ON: Press "ON" key for about 3 seconds, meter will power
on, main menu will be displayed as figure 1. The meter is
on normal working mode, and then user can process
related measurement. (Note: Press key for 3 seconds is
long press, and press 1 second is short press, similar
hereinafter).
OFF: Long press "OFF" for 2 seconds, meter powers off.
Under main interface after power on: Press "F2" to
process unit conversion (dBm or xW); Press "F1", “Record
save prompt” will shine, press “OK” to complete the record
storage; exit save state automatically without operation in
10 seconds. 99 records could be stored.
5.2 Relative value (differential loss)
Under main interface, long press "▼" button to enter
relative test state; the unit is db, taking the current value as
relative value and the benchmark of the differential loss.

Press "F2" to exit relative value test after finishing test.
5.3 Threshold setup
5.3.1 Under main interface, long press "▲" to enter
threshold management interface.
5.3.2 Choose threshold group number by "▲", "▼", and
then browse three threshold values (1310nm, 1490nm,
1550nm) through "◄", "►" in chosen group.
5.3.3 When setting threshold value, please select the
group or wave need to be modified, and then long press
"OK" to enter threshold edit state. You can use "▲", "▼"
edit threshold value, and use "◄", "►" select value
location, press "OK" to save and exit, press "OFF" to exit
without save.
When browsing threshold value in management interface,
short press "OK" to enable current threshold value, then
you can press "OFF" to exit.
Automatically exit test interface without operation in 10
seconds.
Under main interface, long press “OK” button to delete the
threshold value. Then the value will not be displayed, and
threshold value judgment is invalid.
5.4 Time setting
Under main interface, long press "►" to enter time setting,
can edit time through "▲", "▼", and adjust position by

"►","◄", and then press "OK" to save or press "OFF" to
exit.
Exit automatically without operation in 10 seconds.
5.5 Auto power off
Under main interface, short press "OFF" to switch between
auto power off and manual power off, icon displays when
auto power off; default auto power off without operation in
10 minutes.
5.6 Record browsing and management
Under main interface, long press "◄" to enter record
browse interface, then you can press "▲", "▼" to choose
record. Long press "OK" to delete all records.
Exit automatically without operation in 10 seconds.
5.7 Battery under voltage
Once the battery voltage is below 6.7V (for Lithium battery),
the indicator will be , meter will start alarm and power off,
please charge meter (about 4-6 hours) in time, charge
indicator turns from red to green, it means battery is full
charged.

6. Maintenance
1. Keep the sensor’s head face clean, make sure there’s
no dust, no contamination, don’t use unclean and
nonstandard adapters, don’t insert poor polished surface,
or else it will damage the sensor’s head face.
2. Change the adapter carefully, keep the spared adapters
with sealing tight to avoid of touching dirt.
3. Please cover the dust cap timely if meter is unused,
keep the head face clean, don’t expose the sensor in air
for long time, or inaccuracy of measurement will be
caused if sensor touches dirt.
4. Clean the sensor’s head face regularly.
