5.9. AC CURRENT MEASUREMENT

•
The maximum measurable AC current is 400Arms
Make sure that all the test leads are disconnected
from the meter terminals for current measurement.
•
Any value shown on the display with the
instrument
constitute a problem with the instrument and
these values are not added by the instrument
during the execution of a real measurement
