Neurgailuaren funtzionamendua
Once properly set up and calibrated, the Zerone External S Meter provides real-time readings for various radio parameters. The meter's needle will indicate values on the selected scale (SIG, PWR, SWR, MOD, VOLT, DISC) based on your radio's operation mode (receive or transmit).
Refer to your Yaesu FT-857D or FT-897 transceiver's manual for specific interpretations of these readings in different operating scenarios.

Mantentzea
The Zerone External S Meter is designed for durability. Regular maintenance is minimal but important for continued accuracy and longevity.
- Keep the meter clean and free from dust. Use a soft, dry cloth to wipe the casing and display face.

This section addresses common issues you might encounter with your Zerone External S Meter.
Hidden Menu Access
If you are unable to find menu items No-060 or No-061 in your radio's setup menu, these menus might be hidden. To access them:
- Luze sakatu F key on your radio to open the menu settings.
- Set the relevant menu option to ON to reveal the hidden menus.
- Sakatu F key again to exit and save the settings.
Static Pointer / Zeroing Issues
The instrument is calibrated at delivery. However, transit bumps can sometimes cause the pointer to not rest at zero. If this occurs:
- Locate the black self-zeroing screw on the mask-side of the instrument.
- Gently adjust this screw with a small flathead screwdriver until the pointer rests at the zero mark.
