4. Opstelling

4.1 Battery installasie

The GVDA GD128 Multimeter requires 3 x 1.5V AAA batteries (not included) for operation.

1. Maak seker dat die multimeter afgeskakel is.
2. Vind die batterykompartement aan die agterkant van die toestel.
3. Gebruik 'n skroewedraaier om die batteryklepdeksel oop te maak.
4. Plaas 3 AAA-batterye in en let op die korrekte polariteit (+ en -) soos aangedui in die kompartement.
5. Plaas die deksel van die batterykompartement terug en maak dit met die skroef vas.

Figuur 4.1: Batterykompartement vir 3 AAA-batterye.

4.2 Verbinding van toetsdrade

Connect the test leads to the appropriate input jacks for the desired measurement function. Always connect the black test lead to the COM (Common) jack. Connect the red test lead to the jack corresponding to the measurement type (e.g., VΩHz for voltage/resistance/frequency, mA for milliampere current, 10A for ampere current).

5. Bedryfsinstruksies

The GD128 features both auto-ranging and manual-ranging capabilities. The "SMART" function automatically identifies AC/DC voltage, weerstand en kontinuïteit.

Figure 5.1: Multifunctional Use Range icons.

5.1 Krag aan/af

Druk die Aan / uit-sleutel (2) to turn the multimeter on or off.

5.2 Funksiekeuse

The multimeter typically starts in SMART mode. Press the FUNC (Function) key (12) or SEL key to cycle through different measurement modes within a category (e.g., AC/DC voltage, weerstand/kontinuïteit/diode).

5.3 Common Measurement Functions

Figuur 5.2: Examples of various function tests.

5.3.1 Vlugtage Meting (WS/GS)

• Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
• Select the appropriate AC (~) or DC (---) voltage modus.
• Koppel die toetsdrade parallel aan die stroombaan of komponent wat gemeet moet word.
• Die skerm sal die voltage lees.

5.3.2 Stroommeting (WS/GS)

• Koppel die swart toetskabel aan die COM-aansluiting.
• For current up to 600mA, connect the red test lead to the mA jack. For current up to 10A, connect the red test lead to the 10A jack.
• Select the appropriate AC (~) or DC (---) current mode.
• Verbind die multimeter in serie met die stroombaan wat gemeet moet word.
• Die skerm sal die huidige lesing wys.

5.3.3 Weerstandsmeting (Ω)

• Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
• Select the Resistance (Ω) mode.
• Maak seker dat die stroombaan gedeaktiveer is voordat weerstand gemeet word.
• Verbind die toetsdrade oor die komponent wat gemeet moet word.
• Die skerm sal die weerstandslesing wys.

5.3.4 Capacitance Measurement (F)

• Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
• Select the Capacitance (F) mode.
• Ensure the capacitor is fully discharged before measurement to avoid damage to the multimeter.
• Verbind die toetsdrade oor die kondensatorterminale.
• Die skerm sal die kapasitansielesing wys.

5.3.5 Kontinuïteitstoets (Ω)

• Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
• Select the Continuity mode.
• Touch the test leads to the points you want to check for continuity. A continuous beep indicates a complete circuit.

5.3.6 Diodetoets (→|)

• Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
• Select the Diode Test mode.
• 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. Reverse the leads; an open circuit (OL) reading indicates a good diode.

5.3.7 NCV (Nie-kontakvolume)tage) Meting

• Kies die NCV-modus.
• Move the NCV sensor area (1) near the conductor. The multimeter will beep and the warning indicator (4) will light up with increasing frequency as it detects AC voltage.

• Sekering vervanging: If the current measurement function fails, the fuse may be blown. Refer to the warning label inside the battery compartment for fuse specifications (e.g., F600mA/250V, F10A/250V). Ensure the multimeter is off and test leads are disconnected before replacing fuses.
• Berging: If the multimeter is not used for a long period, remove the batteries to prevent leakage. Store in a cool, dry place away from direct sunlight.

9. Probleemoplossing

If you encounter issues with your GVDA GD128 Multimeter, try the following:

• Geen skerm/aanskakel: Kontroleer batteryinstallasie en maak seker dat batterye nie leeg is nie. Vervang indien nodig.
• Verkeerde lesings: Verify test lead connections, ensure the correct function and range are selected, and check if the circuit is de-energized for resistance/continuity/capacitance tests.
• "OL" Vertoon: Indicates an over-range condition or an open circuit (e.g., when measuring resistance on an open wire).
• Geen kontinuïteitspieptoon: Check if the circuit is truly continuous. If not, the circuit is open.
• Fuse Blown Warning: If the current measurement function is not working, the fuse might be blown. Replace the fuse as per maintenance instructions.
