• If having no idea about the scope of current measured, users shall rotate the range switch to the highest
level, and then rotate it to corresponding level according to the value displayed;
• If LCD shows “OL”, it indicates going beyond the range, and the range switch shall be rotated to a higher
level.
• The maximum input current is 200mA or 20A (depending on the inserting location of red probe). In case
of exceeding rated current, the fuse will be melted or even the instrument will be damaged.
3.5. AC current measurement
• Insert the black multimeter probe into “COM” hole, and the red multimeter probe into “mA” or “20A”
hole (maximum 200mA or 20A);
• Select the knob to a proper ACA range, and connect the test leads crossly to the electric circuit under
test.
Notes
• If having no idea about the scope of current measured, users shall rotate the range switch to the highest
level, and then rotate it to corresponding level according to the value displayed;
• If LCD shows “OL”, it indicates going beyond the range, and the range switch shall be rotated to a higher
level.
• The maximum input current is 200mA or 20A (depending on the inserting location of red probe). In case
of exceeding rated current, the fuse will be melted or even the instrument will be damaged.
3.6. Resistance measurement
• Insert the black multimeter probe into “COM” end, and the red multimeter probe into “VΩHz” end;
• Select the knob to a proper resistance range, and connect the test leads crossly with the resistor under
test.
Notes
• Under the mode of manual range measurement, if having no idea about the scope of resistance measured,
users shall adjust the switch to the highest level;
• If LCD shows “OL”, it indicates going beyond the range, and users shall adjust the range to a higher
level. If the resistance measured is more than 1M, it will take several seconds for the reading to become
stable, and this is normal for measurement of high resistance;
• If the input end is open-circuited, the overload sign “OL” will be displayed;
• The online resistance measurement may be started after it’s confirmed that, all power sources of tested
circuit are cut off, and all capacitors are completely discharged;
• Never input voltage at resistance level.
