Warning
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 temperature probe into the Hz Duty%
terminal and the black temperature probe
into the COM terminal.
