3. Настройка
3.1 Падключэнне харчавання
The external power supply (9-14V DC, 200mA) is primarily for enabling the LED backlight function. It does not affect the measurement capabilities of the device. Ensure correct polarity when connecting the power cable:
- The black and white wires should be connected to the positive pole.
- The black wire should be connected to the negative pole.
3.2 Antenna and Transceiver Connection
The TX-502 features two sets of M-type (SO-239 female) interfaces on its rear panel, each corresponding to a specific frequency range:
- 1.6-200MHz Interface: For HF band operation.
- 125-525MHz Interface: For V/UHF band operation.
Connect your transceiver (transmitter) to the TX interface and your antenna or dummy load to the МУРАШКА interface, ensuring you use the correct frequency range ports for your application.
4. Інструкцыя па эксплуатацыі
4.1 Cross Pointer Reading
The TX-502 features a cross pointer display that simultaneously shows forward power (black pointer), reverse power (blue pointer), and standing wave ratio (red pointer). No calibration is required for this feature. The SWR value is read at the intersection point of the forward and reverse power pointers.
4.2 Функцыі кіравання
The front panel of the TX-502 includes several controls for operation:
- LED ON/OFF Switch: Toggles the backlight for the meter display.
- Ручка дыяпазону: Adjusts the power measurement range. Select between 2W, 20W, and 200W settings.
- FUNCTION Knob: Switches between Average Power (AVG) and Peak Envelope Power (PEP) measurement modes.
- HF/V/UHF Switch: Selects the operating frequency band.
5. Тэхнічнае абслугоўванне
To ensure the longevity and accurate performance of your NISSEI TX-502 SWR/Watt Meter, follow these general maintenance guidelines:
- Уборка: Для чысткі вонкавага боку прылады выкарыстоўвайце мяккую сухую тканіну. Пазбягайце выкарыстання абразіўных ачышчальнікаў або растваральнікаў.
- захоўванне: Захоўвайце глюкометр у прахалодным, сухім месцы, удалечыні ад прамых сонечных прамянёў і экстрэмальных тэмператур.
- Апрацоўка: Handle the device with care to prevent physical damage to the casinг або ўнутраныя кампаненты.
- Сувязі: Periodically check all cable connections for tightness and signs of wear.
6. Выпраўленне непаладак
If you encounter issues with your TX-502, consider the following basic troubleshooting steps:
- No Display/Backlight: Ensure the 9-14V DC power supply is correctly connected and the LED switch is in the 'ON' position. Check the power cable for damage.
- Няправільныя паказанні: Verify that the correct frequency band interface (1.6-200MHz or 125-525MHz) is being used for your application. Ensure all connections to the transceiver and antenna are secure. Check that the RANGE knob is set appropriately for the power level being measured.
- No Readings: Confirm that your transceiver is transmitting power and that the connections are solid.
If problems persist after performing these checks, please contact customer support for further assistance.
