4. Setup

4.1 Battery Installation

1. Ensure the multimeter is turned off.
2. Locate the battery compartment cover on the back of the multimeter.
3. Use a screwdriver to remove the screw securing the battery cover.
4. Insert two (2) AAA batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
5. Replace the battery cover and secure it with the screw.

4.2 Connecting Test Leads

1. Insert the black test lead into the 'COM' (Common) jack.
2. For most measurements (voltage, resistance, diode, continuity, and small current), insert the red test lead into the 'VΩmA' jack.
3. For high current measurements (up to 10A), insert the red test lead into the '10ADC' jack. Ensure the function switch is set to the appropriate current range.

5. Operation

To begin a measurement, turn the rotary switch to the desired function and range. Connect the test leads to the circuit or component under test.

Figure 5.1: The GLANSI Digital Multimeter in use, demonstrating its application for testing electrical circuits. The image shows a person wearing gloves, carefully using the test leads to measure components within an electrical panel, with the multimeter's display clearly visible.

5.1 DC Voltage Measurement (V—)

1. Set the rotary switch to the desired 'V—' (DC Voltage) range (e.g., 200mV, 2V, 20V, 200V, 600V).
2. Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side.
3. Read the voltage value on the LCD display.

Figure 5.2: This composite image illustrates different measurement applications of the GLANSI Digital Multimeter. It shows the multimeter performing DC voltage measurement (top left), AC voltage measurement (bottom left), DC current measurement in milliamperes (top right), and DC current measurement in amperes (bottom right).

5.2 AC Voltage Measurement (V∼)

1. Set the rotary switch to the desired 'V∼' (AC Voltage) range (e.g., 200V, 600V).
2. Connect the test leads across the AC voltage source.
3. Read the voltage value on the LCD display.

5.3 DC Current Measurement (A—)

1. IMPORTANT: To measure current, the meter must be connected in series with the circuit. Turn off power to the circuit before connecting the meter.
2. Set the rotary switch to the desired 'A—' (DC Current) range (e.g., 200µA, 2mA, 20mA, 200mA, 10A).
3. For measurements up to 200mA, connect the red test lead to the 'VΩmA' jack. For measurements up to 10A, connect the red test lead to the '10ADC' jack. The black test lead remains in 'COM'.
4. Break the circuit and connect the test leads in series with the load.
5. Apply power to the circuit and read the current value on the LCD display.

5.4 Resistance Measurement (Ω)

1. Ensure the circuit or component is de-energized before measuring resistance.
2. Set the rotary switch to the desired 'Ω' (Resistance) range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
3. Connect the test leads across the component to be measured.
4. Read the resistance value on the LCD display.

Figure 5.3: This image demonstrates two common uses of the GLANSI Digital Multimeter. On the left, it shows the process of measuring resistance across a component. On the right, it illustrates how to test the quality of a 1.5V or 9V battery by measuring its current output.

5.5 Continuity Test (♫)

1. Ensure the circuit is de-energized.
2. Set the rotary switch to the continuity symbol (♫).
3. Connect the test leads across the circuit path or component.
4. If the resistance is below approximately 50Ω, the meter will emit an audible beep, indicating continuity.

5.6 Diode Test (→|—)

1. Ensure the diode is disconnected from the circuit.
2. Set the rotary switch to the diode symbol (→|—).
3. Connect the red test lead to the anode and the black test lead to the cathode of the diode. The display will show the forward voltage drop.
4. Reverse the test leads. The display should show 'OL' (Open Loop) for a good diode.

5.7 Battery Test (1.5V / 9V)

1. Set the rotary switch to the 'BATT 1.5V' or 'BATT 9V' position.
2. Connect the red test lead to the positive (+) terminal of the battery and the black test lead to the negative (-) terminal.
3. The display will show the battery's voltage. A reading significantly below the nominal voltage indicates a weak or discharged battery.

5.8 HOLD Function

Press the 'HOLD' button to freeze the current reading on the display. Press it again to release the hold function and resume live readings.

5.9 Backlight

Press the backlight button (often indicated by a sun or light bulb symbol) to turn the display backlight on or off, improving visibility in low-light conditions.

7.1 Cleaning

To clean the multimeter, wipe the case with a damp cloth and a mild detergent. Do not use abrasives or solvents. Ensure the meter is completely dry before use.

7.2 Battery Replacement

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use fresh AAA batteries.

7.3 Storage

If the multimeter is not used for an extended period, remove the batteries to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

8. Troubleshooting

• No Display: Check battery installation and ensure batteries are not depleted. Replace if necessary.
• 'OL' or '1' on Display: This usually indicates an over-range condition (measurement exceeds selected range) or an open circuit (no connection). Select a higher range or check connections.
• Incorrect Readings: Verify the function switch is set to the correct measurement type and range. Ensure test leads are properly connected and making good contact. Check battery level.
• No Continuity Beep: Ensure the meter is in continuity mode and the circuit is de-energized. Check if the resistance is above 50Ω.
