Attention!
Current Measurements 10A and uA / mA range are protected by
fuses against over-current. Blown fuses must be replaced for other
measurement with new fuses of the same type. With blown fuses no
current measurement is possible. Do not exceed the maximum
current range, in order to avoid triggering the fuse!
1. Insert the black test lead into the negative COM jack.
2. For current measurements up to 5000µA AC, set the function
switch to the "µA" position and insert the red test lead into the
µA/mA-jack.
3. For current measurements up to 500mA AC, set the function
switch to the "mA" position and insert the red test lead into the
µA/mA-jack.
4. For current measurements up to 10A AC, set the function switch
to the 10A position and insert the red test lead into the 10A-jack.
5. Press the MODE-button until AC "~" appears in the display.
6. Remove power from the circuit under test and open the circuit at
the point where you wish to measure current.
7. Touch the black test probe tip to the negative side of the circuit
and touch the red test probe tip to the positive side of the circuit.
8. Apply power to the circuit.
9. Read the current in the display. The display will indicate the
proper decimal point, value and symbol.
