Do not make 10 A current measurements 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 DC 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 DC, 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 DC, 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 10A DC, 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 "DC" 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 negative side of the cir-
cuit. Touch the red test probe tip to the positive side of the cir-
cuit,

Apply power to the circuit,

Read the current in the display.
