5.4. POSITION
“A ”: DC, AC+DC CURRENT MEASUREMENT
WARNING
The maximum measurable DC or AC+DC current is 1000A. When the
display shows “> 999.9A”, it means that the maximum value the clamp is
able to measure has been exceeded. Exceeding these limits could result in
electrical shocks to the user and damage to the instrument.
We recommend holding the clamp respecting the safety area created by the
hand protection (see Fig. 3)
By positioning the selector switch to “
A
”, the screen to the side
will appear.
