Veikimo režimai

The ATU-100 features several operating modes:

• Automatinis režimas: When a dot ('.') appears on the display, the tuner is in automatic mode. In this mode, the tuner automatically adjusts to achieve the lowest SWR.
• Bypass (BYP) Mode: When a dash ('_') appears on the display, the tuner is in BYP mode, meaning it is bypassed and not actively tuning.
• Rankinis režimas: When both the dot and dash disappear from the display, the tuner is in manual mode, allowing for manual adjustments.

Tuning Process:

1. Ensure the tuner is powered on.
2. Transmit a low power signal (e.g., 5-10W) from your transceiver.
3. Paspauskite žalią TUNE button. The tuner will automatically adjust the inductance (L) and capacitance (C) to minimize SWR.
4. Once tuning is complete, the display will show the SWR value.

Advanced Operating Modes (Test and Fast Test)

• Testavimo režimas: To enter Test Mode, press and hold both the BYP ir AUTO buttons simultaneously, then power on the device. This mode is used for diagnostic purposes.
• Fast Test Mode: To enter Fast Test Mode, press and hold the TUNE, BYP, ir AUTO buttons simultaneously, then power on the device. This mode provides a quicker diagnostic check.

Power Supply and Booster Board

The ATU-100 requires a 10-15 VDC power supply. A DC 5.5 x 2.1 power cable is included. For users who need to power the device from a 5V USB source, a USB 5V to 9V booster board is provided.

USB 5V to 9V Booster Board Instructions:

1. Connect the booster board to a 5V USB power source using a USB cable (not included).
2. Solder the 5.5 connector power cable (included) to the booster board's output terminals.
3. Connect the 5.5 connector to the ATU-100's DC12V input.

ttage Regulation Method:

Norėdami reguliuoti išėjimo tūrįtage of the booster board:

• Locate the potentiometer on the booster board.
• Turn the potentiometer clockwise to increase the voltage.
• Turn the potentiometer counter-clockwise to decrease the voltage.
• Jei išvesties ttage does not adjust initially and remains at the input voltage, rotate the potentiometer counter-clockwise more than 10 turns before attempting to adjust it normally.

Booster Module Characteristics:

• Didžiausia išėjimo srovė: 2A
• Įvesties tomastage: 2V-15V
• Didžiausia išvesties apimtistage: >5V-28V
• Efektyvumas: >93 %

Svarbios pastabos:

• Įvesties tūristage should not exceed the maximum input voltage.
• Peak current output should not exceed 2A.
