4. Opstelling

4.1 Battery installasie

The Terminator TMM 7201 is battery-powered. Batteries are not included and must be installed before first use.

1. Vind die batteryklepdeksel aan die agterkant van die multimeter.
2. Gebruik 'n skroewedraaier om die skroef wat die deksel vasmaak, te verwyder.
3. Verwyder die deksel versigtig.
4. Insert a 9V battery, observing the correct polarity (+ and -).
5. Plaas die deksel van die batterykompartement terug en maak dit met die skroef vas.

4.2 Verbinding van toetsdrade

Die korrekte verbinding van toetsdrade is noodsaaklik vir akkurate en veilige metings.

• Plaas die swart toetsdraad in die COM (common) jack.
• Vir die meeste metings (vol.tage, resistance, diode, continuity, small current), insert the red test lead into the VΩmA domkrag.
• Vir hoë stroommetings (tot 10A), steek die rooi toetsdraad in die 10A domkrag.

5. Bedryfsinstruksies

Always ensure the multimeter is set to the correct function and range before making any measurement.

5.1 Meet DC Voltage (V=)

1. Koppel die rooi toetsleiding aan die VΩmA jack and the black test lead to the COM domkrag.
2. Turn the function selector to the desired DC Voltage (V=) range (e.g., 20V, 200V, 500V). If the voltage is unknown, start with the highest range and decrease as needed.
3. Koppel die toetsdrade parallel oor die komponent of stroombaan wat gemeet moet word.
4. Lees die voltage -waarde op die LCD -skerm.

5.2 Meting van AC Voltage (V~)

1. Koppel die rooi toetsleiding aan die VΩmA jack and the black test lead to the COM domkrag.
2. Turn the function selector to the desired AC Voltage (V~) range (e.g., 200V, 500V).
3. Connect the test leads in parallel across the AC source or component.
4. Lees die voltage -waarde op die LCD -skerm.

5.3 Measuring DC Current (A=)

1. Belangrik: To measure current, the multimeter must be connected in series with the circuit. This means breaking the circuit and inserting the meter.
2. For currents up to 200mA, connect the red test lead to the VΩmA jack. For currents up to 10A, connect the red test lead to the 10A jack. Connect the black test lead to the COM domkrag.
3. Turn the function selector to the appropriate DC Current (A=) range (e.g., 2mA, 20mA, 200mA, 10A). Start with the highest range if the current is unknown.
4. Open the circuit where you want to measure current and connect the test leads in series.
5. Lees die huidige waarde op die LCD-skerm.

5.4 Meting van Weerstand (Ω)

1. Waarskuwing: Maak seker dat die stroombaan gedeaktiveer is en alle kapasitors ontlaai is voordat weerstand gemeet word.
2. Koppel die rooi toetsleiding aan die VΩmA jack and the black test lead to the COM domkrag.
3. Turn the function selector to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
4. Connect the test leads across the component whose resistance you want to measure.
5. Lees die weerstandswaarde op die LCD-skerm.

5.5 Kontinuïteitstoets

1. Koppel die rooi toetsleiding aan die VΩmA jack and the black test lead to the COM domkrag.
2. Turn the function selector to the continuity mode (often indicated by a speaker icon).
3. Touch the test leads across the circuit or component. A continuous beep indicates a low resistance path (continuity).

5.6 Diode-toets

1. Koppel die rooi toetsleiding aan die VΩmA jack and the black test lead to the COM domkrag.
2. Turn the function selector to the diode test mode (often indicated by a diode symbol).
3. Verbind die rooi draad aan die anode en die swart draad aan die katode van die diode. Die skerm sal die voorwaartse volume wys.tage druppel.
4. Draai die drade om. Die skerm behoort 'OL' (Oop Lus) te wys vir 'n goeie diode.

5.7 Transistortoets (hFE)

1. Turn the function selector to the hFE position.
2. Identifiseer of die transistor NPN of PNP is.
3. Insert the transistor leads (Emitter, Base, Collector) into the corresponding holes in the hFE socket on the multimeter.
4. The display will show the hFE (DC current gain) value of the transistor.

6. Onderhoud

6.1 Skoonmaak

Vee die meter met advertensie afamp cloth and a mild detergent. Do not use abrasives or solvents. Ensure the meter is dry before use.

6.2 Batteryvervanging

When the low battery indicator appears on the display, replace the 9V battery as described in Section 4.1. Always use a fresh battery of the correct type.

6.3 Sekeringvervanging

If the current measurement function stops working, the fuse may need replacement. Refer to the specifications for the correct fuse type. Fuse replacement should only be performed by qualified personnel.

7. Probleemoplossing

• Geen skerm: Check if the power button is pressed. Verify battery installation and charge. Replace battery if necessary.
• Verkeerde lesings: Ensure the function selector is on the correct measurement type and range. Check test lead connections. Verify battery charge.
• 'OL' of '1' op skerm: This indicates an overload or an open circuit. The measured value is beyond the selected range, or there is no connection. Select a higher range or check the circuit connection.
• Huidige meting werk nie: Check the fuse. If blown, replace with a fuse of the specified rating.
