Current Measurement-high current
①Switch to the high current range, and the
maximum measured current is 9.999A,
connect the red test pen to the input
terminal , while the black test pen to
the input terminal .
Notice
if the measured current is greater than 10A, it will burn out the fuse.
Please preliminarily evaluate the current before measuring.
NCV measurement
①Switch to NCV gear.
②At this point, slowly approach the NCV
area on the top of the multimeter to the test
point. If the built-in sensor senses an AC
electromagnetic field, the buzzer will emit a
"DiDi" sound. The stronger the electromag-
netic field, the faster the "drip" sound, and
the screen display will change synchronous-
ly, as shown in the following figure:
