3.2.8 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.
DC current ranges are:
DC: 200mA, 10A
AC: 200mA, 10A
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 red 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 of 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 overrange
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.
