Features:
【2in1 Design with 2.8 Inch Color Display】: This product ingeniously integrates digital multimeter and signal generator functions into one device. 2.8-inch color display, with 320*480 resolution, and 5%-100% screen brightness adjustable. 
【Multimeter Function】: It supports DCVoltage, ACVoltage, resistance, diode, on-off, capacitance, frequency, duty ratio test function. Supports 4000 counts True RMS function.
【Signal Generator】: Built-in waveform signal generator, it can generate sine waves, square waves, combination waves, scanning waves, scanning waves and other waveforms. Support coil control and waveform signal storage.
【Manually Parameters Setting】: Support setting VP-p, time, frequency, voltage output, to meet different testing needs. By manually setting these parameters, the user can better control the testing process to achieve optimal test results.
【Coil Control】: Check if the ignition coil is normal, support ignition coil control, solenoid valves control, relay control (support 30V/1A and below coil control), that means it can be applied to most low voltage equipment testing.
【Scanning Waves Output】: It is equipped with a function to generate analogue crankshaft cam signals from low-speed to high-speed operation. Suitable for audio maintenance and coordination circuit maintenance.
【Combined Waves Output】: Support combined waves output, it can be arbitrarily set missing teethsignal without connecting to the computer. Maximum number of combined waves: 99+99.
【Waveform Signal Storage】: Manually adjusting waveform signal parameters allows for storage and loading. 50 sets of waveform parameters are stored.
