F. Duty Cycle Measurement (see figure 8)
To avoid harms to you or damages to the Meter
from eletric shock, do not attempt to measure
voltages higher than 600V AC/DC, although
readings may be obtained.
The duty cycle range is: 0.1%~99.9%.
To measure duty cycle, connect the Meter as follows:
Insert the red test lead into the V Hz terminal
and the black test lead into the COM terminal.
Set the rotary switch to %Hz. Press SELECT to
switch to % measurement mode.
Connect the test leads across with the object
