4.12 AC CURRENT MEASURING
WARNING
Shut down the power of the tested circuit, then connect the meter with
the circuit for measurement.
4.12.1 Connect the black test lead to the COM jack and the red test lead to the mA jack for a maximum of 400mA
current. For a maximum of 10A, move the red lead to the 10A jack.
4.12.2 Set the transform switch at the desired A range position.
4.12.3 Put down the "FUNC." to enter the AC measurement. At mA range, auto range or manual range can be
transformed by putting the “RANGE”.
4.12.4 Connect test leads in series with the load under measurement.
4.12.5 You can get reading from LCD.
NOTE:
•
When only the figure ‘OL’ is displayed, it indicates over range situation and the higher range has to be selected.
•
When the value scale to be measured is unknown beforehand, set the range selector at the highest position.
•
“ ” means the maximum current of mA socket is 400mA, the maximum current of 10A socket is 10A, over-current
will destroy the fuse.
4.13 RESISTANCE MEASURING
WARNING
When measuring in-circuit resistance, be sure the circuit under test
has all power removed and that all capacitors have been discharged
fully.
4.13.1 Connect the black test lead to the COM jack and the red test lead to the
Ω
jack.
4.13.2 Set the transform switch at the
Ω
range position.
4.13.3 Put down the "FUNC." to enter the
Ω
measurement. Auto range or manual range can be transformed by
putting the “RANGE”.
4.13.4 Connect test leads across the resistance under measurement.
4.13.5 You can get reading from LCD.
NOTE:
•
When only the figure ‘OL’ is displayed, it indicates overrange situation and the higher range has to be selected.
•
When the input is not connected, i.e. at open circuit, the figure ‘1’ will be displayed for the overrange condition.
•
For measuring resistance above 1M
Ω
, the meter may take a few seconds to get stable reading.
4.14 CAPACITANCE MEASURING
WARNING
To avoid electric shock, be sure the capacitors have been discharged
fully before measuring the capacitance of a capacitor.
4.14.1 Connect the black test lead to the COM jack and the red test lead to the jack.
4.14.2 Set the transform switch at the
Ω
range position.
4.14.3 Put down the "FUNC." transformed at measurement.
4.14.4 Before connect test leads across two sides of the capacitor under measurement, be sure that the capacitor
has been discharged fully.
4.14.5 You can get reading from LCD.
NOTE:
•
It takes certain time (200
µ
F range 30 seconds) to steady the reading when measuring high capacity.
•
When measuring low capacity range under the open circuit, put down the “REL” to make the display show “000”,
then you might get reading from it.
4.15 DIODE TESTING
4.15.1 Connect the black test lead to the COM jack and the red test lead to the
jack.
4.15.2 Set the transform switch at the
Ω
range position.
4.15.3 Put down the "FUNC." transformed at test.
