DC current measurements
WARNING:
To avoid electric shock, do not measure DC current on any
circuit whose voltage exceeds 250V.
CAUTION!
Do not make 10A 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 4000µA DC, set the function
switch to the µA position and insert the red test lead banana
plug into the V
Ω

µ
A jack,
•
For current measurements up to 400mA DC, set the function
switch to the mA position and insert the red test lead banana
plug into the V
Ω
TEMPHz%mA
µ
A jack,
•
For current measurements up to 20A 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
circuit. Touch the red test probe tip to the positive side of the
circuit,
•
Apply power to the circuit,
•
Read the current in the display.
