stable.
6. This DC currrent measurment result is more accurate.
The Meter adopts relative value zeroing.
When measuring DC current, if the reading is positive, then the current direction
is from up to down (see figure 9: the front case face up while the bottom case
face down)
When current measurement has been completed, disconnect the connection
between the conductor under test and the jaw, and remove the conductor away
from the transformer jaw of the Meter.
