5. Torolàlana fananganana
5.1. Fametrahana bateria
- Locate the battery compartment on the back of the KPV-53 device.
- Sokafy ny fonon'ny batterie.
- Insert three (3) AAA 1.5V alkaline batteries, ensuring correct polarity.
- Akatona tsara ny saron'ny efitrefitra bateria.
5.2. Fampifandraisana ny tariby fibre optique
The KPV-53 features a 2.5mm universal interface for the Optical Power Meter and a dedicated port for the Visual Fault Locator. Ensure to use the correct adapter for your fiber type.
- Remove the dust cap from the desired port (OPM or VFL).
- Clean the fiber optic connector end-face thoroughly using appropriate fiber cleaning tools.
- Insert the cleaned fiber optic connector into the device port. For OPM, the standard connector is SC UPC, but adapters for FC, ST, and LC are available (optional).
- Ataovy azo antoka ny fifandraisana azo antoka.

6. Torolàlana miasa
6.1. Power On/off
- Mba hampandeha ny fitaovana, tsindrio ary hazòny ny fahefana bokotra (
) mandra-pahazava ny fampisehoana. - Mba hialana amin'ny herinaratra, kitiho ary hazony ny fahefana button again. The device also features an automatic shutdown function after 5 minutes of inactivity.
6.2. Optical Power Meter (OPM) Function
- Connect the fiber optic cable to the OPM port as described in Section 5.2.
- Tsindrio ny Halavany onjam (λ) button to cycle through the available calibrated wavelengths (850nm, 980nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm) until the desired wavelength is displayed.
- The current optical power measurement will be shown on the LCD in dBm, dB, or uW.
- Setting Reference (REF) and Unit (dB/dBm): Tsindrio ny REF/dB button to switch between absolute (dBm) and relative (dB) measurements. To set a reference value for relative measurements, press and hold the REF/dB bokotra.
- calibration: For calibration, connect the KPV-53 to a light source of the same wavelength. Simultaneously press the REF/dB SY VFL keys to enter the adjustment interface. Use the Halavany onjam (λ) key for downward adjustment and the REF/dB key for upward adjustment. Once the desired calibration is achieved, press the VFL key to save the parameters.

6.3. Visual Fault Locator (VFL) Function
- Connect the fiber optic cable to the VFL port as described in Section 5.2.

8. Famahana olana
- Tsy mandeha ny fitaovana:
- Jereo raha voapetraka tsara ny bateria ary ampy ny fiampangana. Soloy ny bateria raha ilaina.
- Famakiana OPM tsy marina:
- Ensure the fiber optic connectors are clean. Verify that the correct wavelength is selected on the OPM. If readings are consistently off, consider recalibrating the device as per Section 6.2.
- VFL laser is not visible:
- Confirm that the fiber optic cable is properly connected to the VFL port. Ensure the VFL function is activated by pressing the VFL button. Check for any obstructions in the VFL output port.
9. Torohevitra ho an'ny mpampiasa
- Always clean fiber optic connectors before use to ensure accurate measurements and prevent damage to the device's optical ports.
- Utilize the appropriate fiber adapter for your specific connector type (SC, FC, ST, LC) to ensure a proper and secure connection.
- Regularly check the battery levels, especially before critical testing, to avoid interruptions during operation.
- When using the VFL, be mindful of the Class 3b laser and avoid direct eye exposure.
