Batterie : La batterie int\u00e9gr\u00e9e \u00e0 l'appareil est une batterie sp\u00e9ciale au lithium-ion polym\u00e8re. La tension de charge est de 5 V,<\/p>\n\n\n\n

et la temp\u00e9rature de charge varie entre 0 \u00b0C et 50 \u00b0C. Lorsque la temp\u00e9rature ambiante est trop \u00e9lev\u00e9e, le<\/p>\n\n\n\n

La charge s'interrompra automatiquement. Il est recommand\u00e9 de recharger la batterie de l'appareil tous les mois afin d'\u00e9viter<\/p>\n\n\n\n

d\u00e9faillance de la batterie due \u00e0 une autod\u00e9charge apr\u00e8s un stockage prolong\u00e9. La plage de temp\u00e9rature de la batterie pendant<\/p>\n\n\n\n

La temp\u00e9rature de stockage \u00e0 long terme est comprise entre -20 \u00b0C et 45 \u00b0C.<\/p>\n\n\n\n

Veuillez utiliser l'adaptateur secteur sp\u00e9cifique fourni avec cet appareil et vous en tenir strictement \u00e0 cette alimentation externe.<\/p>\n\n\n\n

conform\u00e9ment aux sp\u00e9cifications, sous peine d'endommager l'\u00e9quipement.<\/p>\n\n\n\n

Nettoyage de l'extr\u00e9mit\u00e9 de la fibre : avant le test, nettoyez l'extr\u00e9mit\u00e9 de la jonction de fibre optique \u00e0 tester avec de l'alcool.<\/p>\n\n\n\n

OPM
The function is used to test the power of optical signal 
and insertion loss of various devices and optoelec
tronic components. It can identify and measure the 
frequency of 270\/330\/1000\/2000Hz optical signal.
Wave: switch the working wavelength
Reference: set current power as reference power
CAL: enter the user calibration mode and 
calibrate with the standard light source
TWINS: identify the wavelength and frequency of the 
tested laser source. This function is used with the twins 
function of the local laser source-50~+26dBm: received power\uff1e-10dBm-70~+6dBm: received power\uff1e-30dBm
Absolute power, relative power andlinear power are converted as follows:PAbs.=10lgPLin.\/1mWPRel.=P Abs.-PRef.<\/p>\n\n\n\n

 VFL
Visible red light (650 nm) is injected into theoptical fiber, and the position of the opticalfiber fault point can be judged convenientlyand accurately by observing the leakageposition on the measured fiber. It is suitablefor the detection of bare optical fibers,jumpers and other high loss sections causedby near-end faults and micro-bending ofoptical fibers and cables which can leak red lights.
Normal: turn on red light, continuous light
1Hz: red light source flashes once in 1 second
2Hz: red light source flashes twice in 1 second
Close: turning off red light
