D. Instructions

1. Front Panel

The front panel features a clear LCD display (1) for readings. Below the display are two buttons: 'HOLD' (2a) for freezing the current reading and activating the backlight (long press), and 'SELECT' (2b) for toggling between different measurement modes or functions (AC/DC, Diode/Capacitance/Continuity, °C/°F). A prominent rotary switch (3) allows users to select the measurement mode or range, starting from 'OFF' and proceeding clockwise through AC/DC Voltage (V), AC/DC Voltage (mV), NCV (Non-Contact Voltage), Capacitance, Temperature, AC/DC Current (A), AC/DC Current (mA), Diode/Continuity, and Resistance. The device has three input terminals: VmAµA Hz (4) for voltage, resistance, capacitance, frequency, and low current measurements; COM (5) as the common terminal for all measurements; and 10A (6) for high current measurements.

2. Measure AC/DC Current

1. Connect the black test lead to the COM Terminal and connect the red test lead to the VmAµA Hz Terminal or the 10A Terminal (choose based on the value of current).
2. Turn the rotary switch to the 400µA~10A Mode.
3. Break the circuit path to be measured. Then connect the test leads across the break and apply power.
4. Read the measured current on the display.

Caution: a. Do not measure current that exceeds the MAX Value as indicated in the Specifications. b. Use the 10A Terminal and the Current-10A Mode when you are measuring an unknown current. Then switch to the other terminals if necessary. Do not input voltage exceeding 36V DC or 25V AC when you are at the setting of measuring current.

3. Measure AC/DC Voltage

1. Connect the black test lead to the COM Terminal and connect the red test lead to the VmAµA Hz Terminal.
2. Turn the rotary switch from 400mV~600V range.
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 NCV (Non-Contact Voltage)

1. Turn the rotary to NCV Mode.
2. Hold the product and move it around; the built-in beeper will beep when the inner sensor detects AC voltage nearby. The stronger the voltage is, the quicker the beeper beeps.
3. Put the red probe into the VmAµA Hz terminal, then use the black probe to touch the Live line and Neutral line of the Main supply. You can judge the L-line or N-line by the beeps; if you can hear strong beeps, this is the L-line, or it's an N-line.

5. Measure Resistance

1. Connect the black test lead to the COM Terminal and connect the red test lead to the VmAµA Hz Terminal.
2. Turn the rotary switch from 400Ω~40MΩ range, 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.

6. Measure Continuity

1. Connect the black test lead to the COM Terminal and connect the red test lead to the VmAµA Hz Terminal.
2. Turn the rotary switch from 400Ω~40MΩ range.
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.

7. Measure Diode

1. Connect the black test lead to the COM Terminal and connect the red test lead to the VmAµA Hz Terminal.
2. Turn the rotary switch 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.

8. Measure Capacitance

1. Connect the black test lead to the COM Terminal and connect the red test lead to the VmAµA Hz Terminal.
2. Turn the rotary switch 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 stabilized.

Caution: a. Disconnect circuit power and discharge all capacitors before you test capacitance.

9. Measure Frequency

1. Connect the black test lead to the COM Terminal and connect the red test lead to the VmAµA Hz Terminal.
2. Turn the rotary switch to the Frequency Mode.
3. Touch the probes to the desired test points of the circuit.
4. Read the measured frequency value on the display.

Caution: a. The Frequency Mode only applies to measure high frequency with low voltage.

10. 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 the SELECT button.
4. To disable the Auto Power Off function, hold down the SELECT button when turning on the product; you will hear five beeps if you have successfully disabled the function.

E. General 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.

• Do not operate the product around hot, wet, flammable, explosive or magnetic environments.
• Clean the product with a damp cloth and mild detergent; do not use abrasives or solvents.
• Remove the input signals before you clean the product.
• Remove the batteries if you will not use the product for a long time to prevent possible battery leak.
• 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.
• Replace fuses as above steps. Use only fuses of the same type as the original ones.

Warning:

• Do NOT exceed the "maximum value" indicated in the Specification.
• Do NOT input voltage at the Current Mode, the Resistance Mode, the Diode Mode, or the Continuity Mode.
• Do NOT use the product when the batteries or the battery cover is not placed properly.
• Turn off the product and remove the test leads from the test points before changing batteries or fuses.
