ATU-100 Options:
Access Way:
After turning on power supply, press and hold TUNE button and turn on power switch at the same time. Release the TUNE button after hearing the sound of relay. OPTIONS is displayed on the screen, after a short stay, it automatically enters setting modes.
Description of Each Setting Item:
• Auto Mode (ON/OFF):
If you plan to use the device without additional buttons, you can enable the automatic mode by setting the value to ON. The default value is ON.
• Show Loss (ON/OFF):
Indicating the power delivered to the antenna and efficiency of fider and transmitter when input power is enough for correct SWR measuring.
• Fider Loss (0.0-9.9):
This value uses for counting the power delivered to antenna. The loss value can be found in the reference data for the used cable or you can measure the exact value yourself.
• Auto Delta (1.3-3.0):
The default value is 1.3. That is, when the automatic mode is activated, the tuning process will be triggered when the SWR is above 1.3 and when it changes to (1.3-1).
