1、7 inch color touch screen plus rotary encoder display operation. 2、the instrument has a group of pin-plug type electric output, group electric needle output, independently controllable, without interfering with each other. 3、time setting function: time range of 0min ~ 99min adjustable, a single step of 1min. 4、Electrotherapy output parameters: 1 Each channel has 1 group of electric output, including A/B two roads, A road and B road output is opposite. The output waveform is a combination of square wave and exponential wave; 2 The pulse frequency is adjustable from 0.5 Hz to 10 Hz, with a single step of 0.1 Hz for frequencies from 0.5 Hz to 1 Hz, and a single step of 1 Hz for frequencies from 1 Hz to 10 Hz; 3 Pulse width is adjustable from 0.1ms to 10ms, with a single step length of 0.05ms when the pulse width is 0.1ms to 1ms, and a single step length of 0.5ms when the pulse width is 1ms to 10ms; 4. Output intensity: the peak value of current Ip-p is adjustable from 0mA to 99mA. 5、electroacupuncture therapy output parameters: 1 The carrier frequency is 500Hz±10%; the frequency of modulating wave is adjustable from 0.5Hz to 10Hz; when the frequency is 0.5Hz to 1Hz, the single step is 0.1Hz, and when the frequency is 1Hz to 10Hz, the single step is 1Hz, with the tolerance of ±10%; 2 Pulse width is adjustable from 0.1ms to 1ms, with a single step of 0.05ms and a tolerance of ±10%; 3 Output intensity: the therapeutic instrument electro-acupuncture each channel independent output, in 250 load impedance; each road electro-acupuncture output current peak value Ip-p from 0mA ~ 99mA adjustable, tolerance ±15%. 4 Continuous operation time is more than 8h. The output of specific low-frequency pulse current stimulates the nerves and muscles, promotes the reconstruction of neural pathways and functional recovery, can cause rhythmic muscle contraction, improve muscle strength and prevent muscle atrophy.
