This signal generator has powerful functions for you to use. The portable size of this signal generator makes it convenient for daily use and carry. This tool can be widely used for PLC and DCS system debugging, valves positioner adjustment, inverter detection , etc. Features: Portable Size: The small size of this tool is very convenient for everyday use, you can easily pocket it for storage and carrying. The 2.4-inch backlit display can clearly display data for your convenience data reading. With the function of real-time curve display, the curve can display the change trend of the input or output signal. Wide Applications: This tool can be widely used for PLC and DCS system debugging, valves positioner adjustment, inverter detection, etc. With a history viewing function, you can view past data at any time. Powered by built-in lithium battery, the remaining power is displayed on the screen, so that you can recharge it in time when there is no power, without affecting your use. The cover is made of ABS material and has silicone protection, which can effectively avert damage to the instrument from falling and greatly prolong its service time.
