Ac Current Measurements - Sonel CMM-10 Manual De Uso

AC current measurements

To avoid electric shock, do not measure AC current on any
circuit whose voltage exceeds 250 V.
Do not make current measurements on the 10 A scale for
longer than 30 seconds. Exceeding 30 seconds may cause
damage to the meter and/or the test leads.
In order to realise a measurement of AC current, it is necessary
to realise the following actions:

Insert the black test lead banana plug into the negative COM
jack,

For current measurements up to 4000 µA AC, set the function
switch to the µA position and insert the red test lead banana
plug into the VΩTEMPHz%mAμA jack,

For current measurements up to 400 mA AC, set the function
switch to the mA position and insert the red test lead banana
plug into the VΩTEMPHz%mAμA jack,

For current measurements up to 10 A AC, set the function
switch to the 10A position and insert the red test lead banana
plug into the 10A jack,

Press the MODE button to indicate "AC" on the display,

Remove power from the circuit under test, then open up the
circuit at the point where you wish to measure current,

Touch the black test probe tip to the neutral side of the circuit.
Touch the red test probe tip to the "hot" side of the circuit,

Apply power to the circuit,

Read the current in the display.
