Warning
Should this test tool be used with AC coupling selected, or manual operation of amplitude or time base ranges, the measuring results displayed on the screen may not be representative of the total signal. This can result in the presence of dangerous voltages of more than 42V peak (30V rms), not being detected. To guarantee user safety, all signals should first be measured with DC coupling selected and in fully automatic mode. This ensures that the full signal content is measured.
