Specification: Item Type: Tuner Material: Aluminum Alloy Model: ATU 100 Pro+ Power Supply Voltage Range: 10-15V DC Display Screen: 0.96 Inch Organic Light Emitting Diode Operating Frequency: 1.8-55 MHz USB Charging Current: 1A Battery Model: 3.6V Lithium Battery 1350MAH (Built in) Maximum Current: 400mA Maximum Power: 100W Maximum Measurable Power: 150W Minimum Power for Setting Start: 5W Minimum Measurable Power: 0.1W Power Measurement Step Below 10W: 0.1W Power Measurement Step Above 10W: 1W Power Measurement Accuracy: 10% Specified Maximum Inductance: 8.53uH Capacity Minimum Installation Step of Inductor: 0.05μH Maximum Installation Capacity: 1869pF capacitor Minimum Capacitor Installation Step: 10pF ATU Tuner Product User Manual: 1. Update to the latest firmware version 3.1. 2. New configuration interface, eliminating the need for repeated flashing and purchasing a burner. 3. Optimized power measurement calibration algorithm, more accurate power measurement. 4. Configuration Interface Description: Access Method: Press and hold the TUNE button while simultaneously turning on the rear power switch. Release the TUNE button when the OPTIONS screen appears to enter the settings interface. Operation Mode: Short press the TUNE button to modify the current value. Long press the TUNE button to switch settings. Description of Each Option: Auto Mode (ON OFF): Freely control the automatic mode of the tuner, eliminating the need for an automatic button, more convenient to use. If you do not intend to use the device, you can set the value to ON to enable auto mode. The default value is ON. Loss Display (ON OFF): Arbitrary control loss calculation display interface, more intuitive display. When the input power is sufficient to accurately measure SWR, it indicates the power sent to the and the efficiency of the and transmitter. Fider Loss (0.0‑9.9): Define cable loss value for more accurate efficiency calculation. This value is used to calculate power sent to the . Loss value can be found in the reference data of the cable used, or you can measure the accurate value yourself. Auto (1.3‑3.0): Customize SWR starting value in auto mode, autonomously control SWR adjustment range, with a wider application range. The default value is 1.3. When the auto mode is activated, the optimization process will be triggered when the SWR is above 1.3 and becomes (1.3-1). Power on Display (0‑95s): Customized screen auto shutdown time, power saving during standby Set the luminous display time in seconds. When any button are pressed and RF power input, the backlit will light up. The default value is 00. PackageList: 1 x Tuner 1 x USB Cable 1 x User Manual Note: 1. Insufficient adjustments may occur within 5W, so do not lower it than 5W. 2. It is recommended to not exceed 30W of maximum power when tuning. (You can set it to 100W and operate at this power after tuning, otherwise it may burn out.) 3. You need to use a voltage of 9‑12V to start the ATU 100. If you use a mobile power source or a computer USB interface power output, you cannot start the ATU 100 due to their low voltage.
