For better accuracy when measuring the DC offset of an AC voltage, measure the
AC voltage first. Note the AC voltage range, then manually select a DC voltage
range equal to or higher than the AC range. This procedure improves the accuracy
of the DC measurement by ensuring that the input protection circuits are not activated.
