5. ACA Measurement
1. Insert the black lead into "COM" terminal, and red lead into
"mA" terminal (max 200 mA), or red lead into "10A" terminal
(max 10A)
2. Tern the knob to the ACA Range, then connect the test
leads into the tested circuit in series.
Note:
1. If the tested current is unknown beforehand, should turn
the knob to the highest range, and then turn to the relative
range according to the value displayed on LCD.
2. If LCD displays "1", it indicates overload, should turn the
knob to the higher range
3. The max input current is 200mA or 10A, it depends on the
location the red lead is inserted. When measuring 10A,
note it will affect the accuracy of measurement and
damage the instrument to continuously measure large
current to make the circuit heat
6. Resistance Measurement
1. Insert the black lead into "COM" terminal, and red lead into
"V/Ω/Hz" terminal
2. Turn the knob to the Resistance Range, then connect the
test leads across the tested circuit
Note:
1. If the tested value exceeds the range selected, LCD
displays "1", should turn the knob to higher range; When
the tested value exceeds 1MΩ, it is normal to take several
seconds to make the reading stable.
2. When the input terminal is open circuit, LCD displays the
status of overload.
3. When measuring in-circuit resistance, to make sure the
power of the tested circuit has been turned off and all the
capacitors has been discharged completely.
