The latest firmware version is 3.2: -SWR greater than 1.1 automatically activates tuning. 3.2 The program can be tuned under 5W. However, too low a value may result in insufficient fine-tuning. Parameter description: - Power supply range: 10-15 VDC. -Max current: 450 mA. - Maximum working power: 100 watts. - Maximum measured power: 150 watts. - Minimum power for tuning start: 1 watt. -Recommended maximum power when tuning does not exceed 30 watts. (After tuning, you can set 100 watts and work with this power) - Minimum measured power: 0.1 watts. - Step for measuring power below 10 watts: 0.1 watts. - Step for measuring power over 10 watts: 1 watt. - Accuracy of power measurement: 10%. - Maximum inductance set: 8.5 uH -Minimum step to adjust the inductance: 0.1uH - Maximum installed capacity: 1870 pF -Minimum step to adjust the capacity: 10 pF Box contents: weight: 550 g. - 1 x automatic antenna tuner mounted machine with metal housing (no battery). - DC5.5 x 2.1 power cable x 1. - 1 x USB 5 V to 9 V booster board. Note: 1. Insufficient tuning may occur within 5W. So don't try to be lower than 5W. 2. Recommended maximum power when tuning not over 30 watts. (After tuning, you can set larger watts, otherwise it will burn easily) 3. You need to use 9-12V for the ATU-100 to start. If you use a mobile power supply or computer USB port for power output, you cannot start the ATU-100 because its voltage is too low.
