Overload protection: 0.6A/250V fuse; 10A/250V fuse.
Frequency response: 40
－
400Hz. Duty Cycle Display: (0.1%-99.9%).
XII. Resistance
1. Press “ “ button, and respectively plug the red and black meter pens
into the holes of “ ”and “COM”.
2.Circularly press “ “ button and select resistance measurement.
Meanwhile, a corresponding symbol will appear on the LCD screen.
In automatic resistance measurement mode, you could select manual
measurement by pressing "Range".
Caution
:
a) When measuring the capacity, all the powers within the tested circuits must be disconnected and the capacitance shall be
sufficiently discharged.
b) When measuring the resistance, any occurrence of voltage may Lead to inaccurate readings, and if the 250V protection
voltage is exceeded, it may damage the meter or threaten the safety of the user.
c) When the range of 600
Ω
is in use, first sort-circuit the meter pens and measure the resistance of the lead wires and then
deduct it in the actual measurement.

XIII. Diode and On-and-Off Test
1. Press “ ” button and respectively plug the red and black pens
into “ ”and“COM”.
2. Circularly press “ ” button to select the diode or buzzer measurement. In Diode mode, LDC screen displays " "
and voltage symbol, and the buzzer symbol " " is also displayed on the screen.
3. Connect the red meter pen to the positive of the diode, the black meter pen to the negative of the diode.
Caution
:
a) In case the diode is open circuit or the polarities are connected reversely, “OL” will be displayed on the screen.
b) When checking the diode, all the powers within the tested circuits must be disconnected and the capacitance shall be
sufficiently discharged.
c) When the measurement is completed, immediately disconnect the meter and the measured circuit.
