Mastering the Art of Soldering
Note
:
1. If the range of the voltage to be measured is unknown, put the range switch to the highest
rank, then according to the value displayed, turn to the corresponding range;
2. If on the display is shown "1", this means that the range is exceeded and the range switch
must be set to a higher gear;
3. Do not measure a voltage over 500 V, because there is a risk to damage the instrument
circuit;
4. When measuring a high voltage circuit, pay attention not to touch any high voltage part of
the circuit.
AC voltage measurement
1. Insert the black probe to "COM" and the red probe to "V/Ω";
2.
Put the range switch to the corresponding ACV range and then put the test probes to the
source to be measured.
Note
:
1. If the range of the voltage to be measured is unknown, put the range switch to the highest
rank, then according to the value displayed, turn to the corresponding range;
2. If on the display is shown "1", this means that the range is exceeded and the range switch
must be set to a higher gear;
3. Do not measure a voltage over 500 Vrms, because there is a risk to damage the
instrument circuit;
4. When measuring a high voltage circuit, pay attention not to touch any high voltage part of
the circuit.
DC current measurement
1. Insert the black probe to "C
OM". The red probe can be inserted to "V/Ω" for measuring up
to 200 mA, or insert the red probe to "10 A" for a maximum 10 A measurement;
2.
Put the range switch to the corresponding DCA range and then put the multimeter (the 2
probes) in series with the part of the circuit that you want to measure how much current it
draws. The polarity will be shown on the display.
Note
:
1. If the range of the current to be measured is unknown, put the range switch to the highest
rank, then according to the value displayed, turn to the corresponding range;
2. If on the display is shown "1", this means that the range is exceeded and the range switch
must be set to a higher gear;
3. The maximum input current is 200 mA or 10 A (depending on the port that the red probe
was inserted). If you try to measure a current higher than the maximum input specifications,
the fuse will blow. Check the fuse if you have no reading on the display.
Resistance measurement
1. Insert the black wire to "COM" and the red wire to the "V/
Ω" port;
2. Put the range switch to the corresponding resistor range and connect the two test probes
to the element you want to measure.
Note
:
1. If the resistance value exceeds the selected range value, on the display will be shown "1"
and the range switch should be changed to a higher gear. When the measured resistance
