･ When the input is less than a certain level of measurement range, depending
on using the input unit, the display value is forced to zero. See the
specifications of the input unit to be used.
･
When measuring a high frequency voltage to earth (for example the
secondary side of an inverter), errors may occur in the measurement values.
