Connection of the test leads during LOW 10A test.
3. Set the conductor area by mean the F3 and F4 keys.
4. Connect the 230V~ 50Hz Power supply socket of the instrument to a power
socket using the C5700 cable.
5. Press the START key. The instrument will execute the measurement..
WARNING
If the instrument displays "Measuring" it means that it is effecting the
measurement. During this phase the instrument test leads are not to be
disconnected.

At the end of the test the
instrument emits an
acoustic signal (indicating
that the voltage Drop is
inside the limits displayed
in the following Table) and
display the screen
alongside.
