Current measurement

Warning
To avoid damage to the meter
or injury if the fuse blows, never
attempt an in-circuit current
measurement where the open-
circuit potential to earth is greater
than 250V.
To avoid damage to the meter,
check the meter's fuse before
proceeding. Use the proper
terminals. function, and range for
your measurement. Never place
the test leads in parallel with a
circuit or component when the
leads are plugged into the current
terminals.
Current is the flow of electrons
through a conductor.
The Meter's DC current ranges are
20.00mA, 200.0mA and 10.00A;
AC current ranges are 20.00mA,
200.0mA and 10.00A.
To measure current:
1. Turn off the power of the measured
circuit. Discharge all the high
voltage capacitors.
2. Set the rotary switch to the proper
range.
3. Connect the black test lead to
the COM terminal and the the
red test lead to the mA terminal
for a maximum of 200mA. For a
maximum of 10A, move the red
test lead to the 10A terminal.

4. Break the circuit path to be tested.
Connect the black test lead to the
more negative side of the break;
connect the red test lead to the
more positive side the break.
(Reversing the leads will give
a negative reading but will not
damage the Meter).
5. Turn on the power of the measured
circuit, and then read the display.
Be sure to note the measurement
units at the right side of the display
(mA or A). When only the figure
"1" displayed, it indicates over
range situation and the higher
range has to be selected.
6. Turn off the power of the measured
circuit and discharge all the high
voltage capacitors. Remove the test
leads and recover the measured
circuit.
