Welcome to our shop! The multifunctional signal generator kit is designed to generate ampere and voltage signals through one module. It features a simple and convenient operation, allowing you to generate 4 to 20mA current signals by rotating a multi-cycle precise potentiometer. The signal generator is equipped with a bright and clear 4-digit LED digital display, which can be used to monitor the output current and voltage. You can easily switch between current and voltage monitors by pressing the switch under the monitor. For accurate display, the module is equipped with current and voltage display calibration potentiometers on the back. If the displayed values are not accurate, you can calibrate them yourself. This signal generator has a wide range of applications, including signal generation, valve adjustment, inverter control, PLC debugging, panel debugging, LED testing, and analog transmitter output. With coarse and fine tuning dual modes, you can set the number of turns separately. The minimum adjustment number of the knob is 0.01mA, and the last number is added or subtracted by 1. After calibration, you can achieve high accuracy linear output with an actual error of 0.01mA. The signal generator is reliable and durable, featuring a 4-bit 0.4-inch high brightness large digital tube for clear visibility. The digital encoder knob is durable and unaffected by the environment. The power supply has reverse polarity protection, and the output can be short-circuited.
