NOTE
Select the measurement range. For the Frequency mode, three types of
measurement can be performed depending on the measurement range.
Frequency can be measured from 0.05 Hz to 5 kHz, RPM can be measured
from 5 to 500 rpm, or commercial power can be measured at P50 or P60 Hz.
In the Frequency mode, the measurement range can be set to P50Hz or P60Hz
for commercial power. Although 0 Hz is the usual zero position, in this case 50
or 60 Hz becomes the zero position.
