This primer describes methods for making measurements using inverter, motor and drive analysis software on oscilloscopes to provide stable, accurate electrical measurements on the inputs, DC buses, and outputs of variable frequency drives, as well as mechanical measurements on the motor. In this. . The inverter seems to have two opposing hot lines (e. -115VAC + +115VAC = 230VAC) rather than neutral/hot wire. Can I measure directly? I've got a DSO1054Z, which has a maximum input voltage of "CAT I 300 Vrms, CAT II 100 Vrms, transient overvoltage 1000 Vpk With RP2200 10:1 probe: CAT II 300. . In this video, you'll learn how to properly use a portable oscilloscope to test and analyze inverter air conditioner boards. We'll guide you through the basics of connecting the device, reading waveforms, and identifying faults in circuits commonly found in inverter AC systems. I am willing to pay for quality, but I don't expect to use it very much, just testing inverter output (so it has to be able to handle high voltage) and maybe. . It's the same as measuring any other AC signal. If the scope is rated for 120 VAC (most are), just place the AC across the vertical input. Visualizing Waveforms Inverters used in HVAC systems typically convert DC voltage to AC voltage. .
