Availaber for different Fiber
1.Available for 800nm~1700nm laser signal
250um bare fiber
900um fiber
2.0mm patch cord
3.0mm patch cord
Availaber for different Fiber
3.No need toreplace the clampblock for different fiber
2.Based on non-destructivetechnology
When measuring 2.0mmand 3.0mm fiberjumper,you must
jumpers,it is notguaranteed that alljumpers can bemeasured.
Tip line
see the promptline to ensurethe correct measurement.
Note due to different manufacturing processesof fiber optic

Operation
Put the fiberinto the fiberlocation and pushdown the
trigger to begintesting. After1~3 seconds, itoutput the
results.
The data in the LCDmeans the signalintensity, if too
weak,it will be"NO".
Use a hood under
strong light

7
Direction and tone
It is themain function totest the directionof the signal
in the fiber. The corresponding indicative ledwill be on.
And ifthe signal carrysdifferent frequency--270Hz,
1kHz, 2KHz, theindicative led willbe on also.

Low power indicate
When the equipmentis operated,the"POWER" ledis
always on,it meansthe battery isfully charged andyou can
keep using it.When the "POWER"led flash, itmeans low
battery energy,please replace thebatteries.
