4. Подешавање

4.1 Инсталација батерије

The Performance Tool W2972 requires two AAA batteries, which are included. To install or replace batteries:

1. Пронађите поклопац одељка за батерију на задњој страни мултиметра.
2. Користите одвијач да бисте одврнули завртањ који причвршћује поклопац.
3. Уметните две ААА батерије, водећи рачуна о исправном поларитету (+/-) као што је назначено унутар одељка.
4. Вратите поклопац и причврстите га вијком.

4.2 Повезивање мерних каблова

Повежите мерне каблове са одговарајућим улазним прикључцима на мултиметру:

• Уметните црни тест кабл у ЦОМ (обични) џек.
• Уметните црвени тест кабл у VΩmA џек за јачину звукаtage, resistance, and low current measurements.
• За мерења велике струје (до 10A), уметните црвени мерни кабл у 10A MAX FUSED Јацк.

5. Упутство за употребу

The rotary dial on the front of the multimeter is used to select the desired measurement function and range.

5.1 Општи рад

1. Turn the rotary dial to the desired function (e.g., V for voltage, Ω for resistance, A for current).
2. Connect the test probes to the circuit or component being tested.
3. Read the measurement on the large LCD display. The multimeter features automatic reverse polarity indication.
4. Притисните тастер ХОЛД дугме да замрзнете тренутно очитавање на екрану. Притисните поново да бисте отпустили.

5.2 Automotive Specific Functions

The W2972 is equipped with specific settings for automotive diagnostics, including tachometer (RPM) and dwell measurements.

Tachometer (RPM) Measurement:

• Окрените окретни точкић на РПМк10 постављање.
• Select the appropriate cylinder setting (4CYL, 6CYL, 8CYL) for the engine being tested.
• Connect the red test lead to the negative terminal of the ignition coil or the tachometer test point, and the black lead to a good ground.
• Start the engine and read the RPM value on the display. Multiply the reading by 10 for the actual RPM.

Dwell Measurement:

• Окрените окретни точкић на ДВЕЛЛ постављање.
• Select the appropriate cylinder setting (4CYL, 6CYL, 8CYL) for the engine being tested.
• Connect the red test lead to the negative terminal of the ignition coil or the dwell test point, and the black lead to a good ground.
• Start the engine and read the dwell angle on the display.

Волtage Testing (Starting, Charging, Fuel Delivery Systems):

• Select the appropriate DC Voltage (V–) range.
• Connect the red test lead to the positive point of the circuit (e.g., battery positive terminal, alternator output) and the black test lead to a good ground.
• Прочитајте књtagе на дисплеју.

Diode Function:

• Turn the rotary dial to the diode symbol (→|–).
• Спојите црвени мерни кабл на аноду, а црни мерни кабл на катоду диоде.
• A forward voltage drop will be displayed for a good diode. Reverse the leads; an open circuit (OL) should be displayed.

6. Одржавање

6.1 Замена осигурача

The multimeter is protected by a fuse. If the current measurement function stops working, the fuse may need replacement.

• The multimeter uses a F0.5AL250V 5X20mm fuse.
• To replace the fuse, open the battery compartment cover as described in Section 4.1.
• Carefully remove the old fuse and insert a new fuse of the correct type and rating.
• Вратите поклопац и причврстите га вијком.

6.2 Чишћење

Обришите мултиметар цasinг са огласомamp тканина. Немојте користити абразивна средства за чишћење или раствараче.

КСНУМКС. Решавање проблема

• Нема дисплеја или бледи дисплеј: Проверите постављање батерија и пуњење. Замените батерије ако је потребно.
• Нетачна очитавања: Ensure test leads are properly connected and the correct function/range is selected. Verify the component being tested is functioning correctly.
• Мерење струје не ради: Check and replace the fuse (refer to Section 6.1).
• RPM/Dwell readings inconsistent or zero: Ensure proper connection to the ignition system and correct cylinder setting. Verify engine is running smoothly.
