If that is true, it''s also safe to measure voltage between two main lines (400V RMS), since the peak-to-peak would be about 112 volts? SAFETY: When I am measuring AC, I will be using the scope from its internal battery or with a isolating transformer (1:1) so
Measuring voltage is a crucial skill when working with electronic circuits, and an oscilloscope is one of the best tools for this task. Unlike a simple multimeter that only gives you a number, an oscilloscope shows you a detailed picture of how the voltage changes over time.

To measure current with an oscilloscope, special accessories such as current probes are needed to convert electrical current into a voltage that can be measured by the scope. This voltage is then displayed on screen along with other parameters such as frequency or power.
Accurate power measurements with an oscilloscope require simultaneous voltage and current measurements. Thus, robust voltage and current probes with appropriate ratings and ranges are critical. Three-phase power converters, such as EV traction inverters, involve more complexity, with more channels and more calculations.
voltage, the voltage drop during cranking, the starter motor current consumption and the battery recovery/charge rate once the engine has started (three component tests in less than 15 seconds). Above is a typical result sheet from the battery test, confirming that the battery, starter motor, and alternator are all functioning correctly.
Voltage probes are connected across the switch, and current probes are connected to measure current through the switch. You can add multiple measurements to get measurements for each switch. The 5/6-PWR analysis packages include these measurements:
Measure the voltage drop: Use the oscilloscope''s measurement functions to determine the peak-to-peak or average voltage drop across the resistor. Calculate the current: Apply Ohm''s law (I = V/R) using the measured voltage drop (V) and the known resistance (R) to calculate the current flowing through the circuit.
