To avoid over charging, a BMS was employed. With my understanding, BMS operated in this way. The BMS monitored voltage across each battery bank. If any one of the banks was over 4.2V, It shorted that bank plus and minus terminals with a resistor to bleed current out and lower its volta...
Connect the oscilloscope probe’s ground wire to the ground on the power supply. If the probe has a sensitivity switch, set it to X 1. Connect the probe to a positive power supply output. Watch for a ripple waveform on the oscilloscope. If you see one, adjust the sensitivity so its pe...
Averaging is great for measuring line regulation, load regulation, and switching ripple. An external trigger is often necessary for this to work. Quote So it is more like using a sufficiently large window (low deflection speed) to get averaging for the build in RMS calculation. One might have...

How to Calculate Instantaneous Voltage. Many circuits experience a time delay between the time a voltage is applied and the time that voltage appears at the circuit. This time delay happens because capacitors in the system have to first charge up to the
. This assumption ensures that the rise time provided is sufficiently fast for characterization. If the rise time needs to be slowed down, this can be achieved with either mathematical filtering in the oscilloscope, or using sufficiently lossy cables or filters. Using this 50% guardband as...
find several settings in the voltage group representing a progression in sensitivity from 200 millivolts (mV) to 500 volts. The dial selections may also include settings for DC and AC voltage. DC voltage is denoted by a straight line, or no line at all, while AC voltage is denoted by a...
