High safety: ASA testing does not require the circuit board to be powered on; ASA testing does not involve circuit principles and does not require the circuit to be in working condition _x000D_ 2. Strong adaptability: ASA testing does not involve the functions of components on the circuit board, so no matter what type of components the circuit is composed of, including digital, analog, mixed digital and analog, etc., it can be tested. _x000D_ Parameters: _x000D_ Voltage: 4V _x000D_ Internal resistance: 50R, 500R, 1K, 2K, 3K, 4K, 5K, 6K, 7K adjustable _x000D_ Frequency: 20Hz, 100Hz, 500Hz, 1kHz, 2kHz, 3kHz, 4kHz, 5kHz, 6kHz, 7kHz, 8kHz, 9kHz, 10kHz, 11kHz, 12kHz, 13kHz, 14kHz, 15kHz adjustable _x000D_ Battery capacity: 3000mah _x000D_ Casing material: ABS _x000D_ Product size: 140.00x80.00x40.00mm _x000D_ Product size: 5.51x3.15x1.57inch _x000D_ _x000D_ Note: _x000D_ 1. The blue terminal is a multiplexed port. When the A channel is the default, the blue terminal outputs a 5V pulse voltage with an interval of 1 second. After the A+B channel is turned on, the blue terminal becomes the B channel signal _x000D_ 2. It is forbidden to measure with electricity!
