5. Setup

5.1. Battery Installation

The multimeter requires AAA and 9V batteries for operation. Batteries are NOT included in the package due to safety reasons during shipping.

  1. Locate the battery compartment cover on the back of the multimeter.
  2. Use a screwdriver to open the battery compartment.
  3. Insert the required AAA and 9V batteries, ensuring correct polarity (+ and -).
  4. Replace the battery compartment cover and secure it with the screw.

5.2. Connecting Test Probes

  1. Insert the black test lead into the "COM" (Common) input terminal.
  2. Insert the red test lead into the "VΩmA+" input terminal for most measurements (voltage, resistance, small current).
  3. For high current measurements (e.g., 10A DC), insert the red test lead into the dedicated "DC10A" jack (if available on your model).

6. Operating Instructions

Always ensure the multimeter is set to the correct function and range before making any measurements. Refer to the product overview for component identification.

6.1. General Measurement Steps

  1. Select Function/Range: Turn the gear knob to the desired measurement function (DCV, ACV, DCA, Ω, BATT, hFE) and appropriate range. Start with a higher range if the value is unknown to prevent damage.
  2. Connect Probes: Connect the black test lead to the COM terminal and the red test lead to the VΩmA+ terminal (or DC10A for high current).
  3. Connect to Circuit: Connect the test probes to the circuit or component you wish to measure.
  4. Read Measurement: Observe the needle on the dial and read the corresponding value on the selected scale.

6.2. Specific Measurement Procedures

6.2.1. Battery Test (9V)

To test a 9V battery:

  1. Set the gear knob to the "BATT" function, specifically the 9V range.
  2. Connect the red test lead to the positive terminal of the 9V battery and the black test lead to the negative terminal.
  3. Read the voltage indicated by the needle on the dial.
Video 6.1: Demonstration of battery testing (0:00 - 0:07).

6.2.2. Resistance Measurement

Before measuring resistance, you must calibrate the meter to zero:

  1. Set the gear knob to the desired "Ω" (Ohms) range (e.g., x1, x10, x100, x1k, x10k).
  2. Short the red and black test leads together.
  3. Adjust the "0Ω ADJ" (Resistance zero adjuster) knob until the needle points exactly to the "0" mark on the resistance scale.
  4. Once calibrated, connect the test leads across the component whose resistance you want to measure.
  5. Read the resistance value from the dial, multiplying by the selected range factor (e.g., if on x100 range and needle reads 50, resistance is 50 x 100 = 5000Ω).
Video 6.2: Demonstration of resistance measurement and zero calibration (0:07 - 0:26).

6.2.3. Diode Measurement

To measure diode load current (LI) and load voltage (LV):

  1. Set the gear knob to the appropriate diode test range (e.g., LI at X10 15mA).
  2. Connect the test leads across the diode.
  3. Observe the readings for load current (LI) and load voltage (LV) on the dial.
Video 6.3: Demonstration of diode load current and load voltage measurement (0:26 - 0:36).

6.2.4. AC Voltage Measurement

To measure AC voltage:

  1. Set the gear knob to the "ACV" function and select an appropriate range (e.g., 250V, 1000V). Ensure the selected range is higher than the expected voltage.
  2. Connect the test leads in parallel across the AC voltage source.
  3. Read the AC voltage value from the dial.
Video 6.4: Demonstration of AC voltage measurement (0:36 - 0:45).

6.2.5. Triode Measurement (hFE)

To measure triode (transistor) hFE:

  1. Set the gear knob to the "hFE" function.
  2. Insert the transistor leads into the corresponding slots in the triode socket (E, B, C for Emitter, Base, Collector). Ensure correct polarity (NPN or PNP).
  3. Read the hFE value from the dial.
Video 6.5: Demonstration of triode measurement (0:45 - 0:55).

6.2.6. Other Measurements (DCV, DCA, Audio Level)

For DC Voltage (DCV), DC Current (DCA), and Audio Level (dB) measurements, follow the general measurement steps, selecting the appropriate function and range on the gear knob.

7. Maintenance

7.1. Cleaning

Wipe the multimeter with a dry, soft cloth. Do not use abrasive cleaners or solvents.

7.2. Storage

When not in use for extended periods, remove the batteries to prevent leakage. Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures.

7.3. Fuse Replacement

If the current measurement function stops working, the fuse may be blown. Replace it with a fuse of the correct rating:

  • For general current measurements: 0.5A/250V (Φ5.2mm×20mm)
  • For 10A current measurements: 10A/250V (Φ5mm×20mm)

To replace the fuse, open the battery compartment cover on the back of the multimeter, as the fuse is typically located within or near this area.

8. Troubleshooting

ProblemPossible CauseSolution
No reading / Meter not turning onDead or incorrectly installed batteries.Check battery polarity and replace with fresh batteries.
Incorrect or unstable readingsIncorrect function/range selected; poor probe contact; uncalibrated resistance.Verify function and range; ensure firm probe contact; perform resistance zero adjustment.
Current measurement not workingBlown fuse.Replace the fuse with the correct rating (refer to Maintenance section).
Resistance measurement always shows infinite (needle doesn't move)Resistance zero adjustment not performed or battery low.Perform resistance zero adjustment; check/replace batteries.

9. User Tips

No specific user tips were available from provided reviews or Q&A. However, general tips for analog multimeters include:

  • Always start with the highest range when measuring an unknown voltage or current to avoid damaging the meter.
  • For resistance measurements, always ensure the circuit is de-energized and the component is isolated.
  • Regularly check the battery level, especially for resistance measurements, as low battery can affect accuracy.
  • When reading the analog scale, look directly at the needle to avoid parallax error. Some meters have a mirror strip on the scale to aid in this.
