1. Encoder knob adjustment; digital constant current control; can be connected to a computer host computer to view curves and control; four-tube synchronous discharge safety design; with timing discharge; stop voltage can be set; true four-wire, zero line loss measurement; accurate calibration ; LCM LCD large screen display; Exquisite animated discharge interface; Wide voltage 200V wide current 25A settings 2. After the main unit is powered on, use the computer online cable to connect to the computer's USB port, and then install the upper computer online software driver, open the software and use it online. Increase the PC computer online background setting function. The computer online background setting is consistent with the host setting. Color style optional function, you can choose your favorite color curve and grid background color arbitrarily 3. The four-tube discharge design is safer. This time, the high-cost multi-tube current evenly shunting synchronous discharge technology is adopted, so that a larger current can be used for long-term stable operation at low voltage and high current, and the anti-burning safety of the discharge tube at high voltage discharge etc. have been improved at the same time, making the overall technical performance of the equipment reach a higher level. 4. Set the required power and temperature. When the device reaches the set threshold, it will automatically display a double reminder of the alarm and the beeping sound of the buzzer and automatically disconnect the power supply Product Description Type: Digital voltage measuring instrument Measuring range: 0-200 (V) Input voltage: 0-200 (V) Output voltage: 0-200 (V) Color: As Shown Material: plastic Package Contents: 1 x host 1 x measuring line adapter board 1 x DC power cord 1 x temperature probe 1 x 10A experience line 1 x computer online line 1 x English manual Only the above package content, other products are not included.
