other Ranges:
All AC voltage ranges are specified from 10% to 100% of range except that the 600V range is
specified from 30% to 100% of range.
When the input terminals are shorted, the display may show a number between 0 and 30 counts;
and when the input terminals are open, the reading may fluctuate due to interference. This is normal
and will not affect measurements.
