What is the True Max DC Input Voltage for the DLM2000 Mixed Signal Oscilloscope?
The actual input limit for the DLM2000 Mixed Signal Oscilloscope is 212V (DC+ACpeak) for not only a 0.01 or 0.001 Hz AC signal but also a DC signal. The reason why 150 Vrms is indicated on the DLM2000 specification sheet is that the safety standard requires the max input voltage to be defined by units of rms.
