KKM781:
The KKM781 is an example of a combination of an oscilloscope and an auto range multimeter that combines all the features of the existing with the digital oscilloscope function. Compliant with the trend, small and portable handheld oscilloscope for field fault detection.
Features:
This is an oscilloscope and multimeter combined test instrument to improve your work efficiency.
200Msps high-speed sampling, 40MHz analog bandwidth, 6000 digital multimeter.
Rotary knob for switching oscillography with three types of waveform scanning mode i.e. automatic mode, regular mode and single-time mode.
Save function for data and waveform in the measurement; a total of 100 sets of data and 50 waveform can be saved.
Parameters i.e. time base and waveform scanning mode can be set in measurement of waveform.
TRMS, measure the virtual value of waveform without taking into account the waveform parameter and distortion.
REL, effectively eliminate the lead resistance, distributed capacitance and interference signal.
The functions include DC/AC voltage/current, resistance, capacitance, frequency, temperature, diode/continuity test, triode.
