6.3. DC CURRENT MEASUREMENT
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.
1. Insert the black test lead banana plug into the
input jack.
COM
2. For current measurements up to
, set the function
6000
µ
A DC
switch to the
µA AC/DC
position and insert the red test lead banana
plug into the
µA/mA
input jack.
3. For current measurements up to
, set the function switch
600mA DC
to the
position

10A DC
the
position and
10A AC/DC
insert the red test lead banana plug
into the
10A
input jack.
5. Press the
Button to indicate "
" on the display.
MODE
DC
6. Remove power from the circuit under test, then open up the circuit at
the point where you wish to measure current.
7. Connect the black test probe tip and the red test probe tip in series to
the circuits current you want to measure
8. Apply power to the circuit.
9. Read the current on the display.
6.4. AC CURRENT (FREQUENCY, DUTY CYCLE) MEASUREMENT
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.
1. Insert the black test lead banana plug into the negative
COM
input
jack.
2. For current measurements up to
6000 µA AC
, set the function
switch to the
µA AC/DC
position and insert the red test lead banana
plug into the
µA/mA
input jack.
3. For current measurements up to
600mA AC
, set the function switch
to the
mA AC/DC
position and insert the red test lead banana plug
into the
µA/mA
input jack.
4. For current measurements up to
10A AC
, set the function switch to
the
10A AC/DC
position and insert the red test lead banana plug
into the
10A
input jack.
5. Press the
MODE
Button to indicate "
AC
" on the display.
6. Remove power from the circuit under test, then open up the circuit at
the point where you wish to measure current.
