Power Remote Control Comprehensive Tester/Power Simulation/Data Tester/Power Remote Control Channel TesterHAD-4055/H141266



Detailed instruction manual

The power remote control comprehensive tester is suitable for engineering construction, engineering acceptance, and daily maintenance testing of power systems. Its performance is reliable and stable, with complete functions and a compact size. It adopts a large screen Chinese display, and the operation is simple and easy.

1.1 FunctionInstructions

Users follow the power system's requirements for remote control signals(The standard for the baud rate and center frequency of FSK modulation transmission is used to send FSK signals with different baud rates from the instrument to the four wire channel. The instrument can detect the error rate of the four wire analog channel through measurement and environmental testing methods, or detect the reception of FSK signals through the monitoring system of remote control equipment. In addition, the instrument can automatically detect the baud rate of the received FSK analog modulation signal.
