Color screen multi-function signal generator, DC voltage and current output, with input measurement, and PWM output. Voltage measurement range: ±50V; voltage DC analog output range: ±12V (with short circuit protection). Current DC analog output range: 0-24mA (can be short-circuited); current measurement range: ±50mA. Output adjustment range: users can set it arbitrarily, such as 0-20mA/4-20mA/0-10V/0-5V, etc., and the corresponding engineering display value can be set by users. PWM pulse square wave output: adjustable frequency 1-150kHz, voltage 5V, current Less than 20mA. With 2.0-inch TFT color screen, 320 x 240 pixels, all values are displayed on one screen, and the Chinese and English interfaces can be switched. High-end digital encoder with large knob adjustment. 3 power supply methods can be output: external 24VDC terminal/USB-TypeC/built-in lithium battery. Color: Black Material: plastic Package Contents: 1 * Multi-function signal generator 1 set * accessories (accessory colors are random, don't accept the specified color) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
