(7) Measure Capacitance
1. Connect the black test lead to the COM Terminal and connect the red test lead to the
VΩHz Terminal;
2. Turn the rotary switch to the Resistance Mode, press SELECT three times to toggle to
the Capacitance Mode;
3. Connect the red probe to the anode side and the black probe to the cathode side of
the capacitor being tested;
4. Read the measured capacitance value on the display once the reading is stablized.
*Caution:
a. Disconnect circuit power and discharge all capacitors before you test capacitance.
(8) Measure Frequency and Duty Cycle
1. Connect the black test lead to the COM Terminal and connect the red test lead to
the VΩHz Terminal;
2. Turn the rotary switch to the Frequency Mode; press SELECT once to toggle to the
Duty Cycle Mode if you want to measure duty cycle;
3. Touch the probes to the desired test points of the circuit;
4. Read the measured frequency/duty cycle value on the display.
*Caution:
a. The Frequency Mode only applies to measure high frequency with low voltage.
(9) Auto Power Off
1. The product automatically powers off after 15 minutes of inactivity;
2. The built-in beeper beeps 5 times 1 minute before power off;
3. To restart the product, press SELECT botton;
4. To disable the Auto Power Off function, hold down the SELECT botton when
turning on the product, you will hear five beeps if you have successfully disabled
the function.
E. Genearl Maintenance
Beyond replacing batteries and fuses, do not attempt to repair or service the product
unless you are qualified to do so and have the relevant calibration, performance test, and
service instructions.
(1) Do not operate the product around hot, wet, flammable, explosive or magnetic
environments.
(2) Clean the product with damp cloth and mild detergent; do not use abrasives or
solvents.
(3) Remove the input signals before you clean the product.
(4) Remove the batteries if you will not use the product for a long time to prevent
possible battery leak.
(5) When “ ” is shown on the display, batteries shall be replaced as below:
1. Loosen the screw and remove the battery cover;
2. Replace the used batteries with new batteries of the same type;
3. Place the battery cover back and fasten the screw.
(6) Replace fuses as above steps. Use only fuses of the same type as the original
ones.
(3) Measure AC/DC Voltage
1. Connect the black test lead to the COM Terminal and connect the red test lead to
the VΩHz Terminal;
2. Turn the rotary switch to the AC Voltage Mode or the DC Voltage Mode;
3. Touch the probes to the correct test points of the circuit to measure the voltage;
4. Read the measured voltage on the display.
*Caution:
a. Do not measure voltage that exceeds the MAX Value as indicated in the
Specifications;
b. Do not touch high voltage circuit during measurements.
(4) Measure Resistance
1. Connect the black test lead to the COM Terminal and connect the red test lead
to the VΩHz Terminal;
2. Turn the rotary switch to the Resistance Mode, and the display will show “OL”;
3. Touch the probes to the desired test points of the circuit to measure the
resistance;
4. Read the measured resistance on the display.
*Caution:
a. Disconnect circuit power and discharge all capacitors before you test resistance.
b. Do not input voltage at the Resistance Mode.
(5) Measure Diode
1. Connect the black test lead to the COM Terminal and connect the red test lead to
the VΩHz Terminal;
2. Turn the rotary switch to the Resistance Mode, press SELECT once to toggle to
the Diode Mode;
3. Connect the red probe to the anode side and the black probe to the cathode side
of the diode being tested;
4. Read the forward bias voltage value on the display;
5. If the polarity of the test leads is reversed with diode polarity or the diode is
broken, the display reading shows “OL”.
*Caution:
a. Do not input voltage at the Diode Mode.
b. Disconnect circuit power and discharge all capacitors before you test diode.
(6) Measure Continuity
1. Connect the black test lead to the COM Terminal and connect the red test lead to
the VΩHz Terminal;
2. Turn the rotary switch to the Resistance Mode, press SELECT twice to toggle to
the Continuity Mode;
3. Touch the probes to the desired test points of the circuit;
4. The built-in beeper will beep when the resistance is lower than 50Ω, which
indicates a short circuit.
*Caution:
a. Do not input voltage at the Continuity Mode.
Warning
：
1. Do NOT exceed the “maximum value” indicated in the Specification;
2. Do NOT input voltage at the Current Mode, the Resistance Mode, the Diode
Mode, or the Continuity Mode;
3. Do NOT use the product when the batteries or the battery cover is not placed
properly;
4. Turn off the product and remove the test leads from the test points before
changing batteries or fuses.
