5. Подешавање

5.1. Инсталација батерије

The Fluke 77-4 is powered by a 9V battery. To install or replace the battery:

1. Уверите се да је мултиметар искључен.
2. Пронађите поклопац одељка за батерију на задњој страни мултиметра.
3. Користите одвијач да бисте отпустили завртањ(е) који причвршћују поклопац.
4. Remove the cover and insert a new 9V battery, observing correct polarity.
5. Вратите поклопац и затегните завртањ(е).

5.2. Повезивање мерних каблова

Always connect the black test lead to the COM jack. Connect the red test lead to the appropriate input jack for your measurement:

• ВΩХз: Фор волtage, resistance, continuity, diode, and frequency measurements.
• мА: For current measurements up to 400mA.
• 10А: For current measurements up to 10A.

6. Упутство за употребу

Before taking any measurement, ensure the test leads are correctly connected and the function dial is set to the appropriate position.

6.1. Мерење AC/DC јачине струјеtage

1. Turn the rotary dial to V~ (AC Voltage) or V (DC Voltagи).
2. Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
3. Touch the test probes to the circuit points where voltagе треба мерити.
4. Прочитајте књtagе вредност на дисплеју.

6.2. Measuring Resistance (Ohms)

1. Пре мерења отпора, уверите се да је коло без напона.
2. Turn the rotary dial to Ω.
3. Connect the black test lead to the COM jack and the red test lead to the VΩHz jack.
4. Touch the test probes across the component or circuit segment.
5. Очитајте вредност отпора на дисплеју.

6.3. Measuring Current (Ampерес)

Опрез: Current measurements require breaking the circuit and inserting the multimeter in series. Incorrect connection can blow the fuse or damage the meter.

1. Искључите струјно коло.
2. Determine the expected current range. For currents up to 400mA, turn the dial to mA and connect the red lead to the mA jack. For currents up to 10A, turn the dial to A and connect the red lead to the 10A jack.
3. Повежите црни тест кабл на ЦОМ прикључак.
4. Break the circuit and connect the test probes in series with the load.
5. Поново укључите коло и очитајте тренутну вредност.
6. De-energize the circuit before disconnecting the multimeter.

6.4. Using HOLD, MINMAX, and RANGE Functions

• ДРЖАТИ: Притисните дугме HOLD да бисте замрзнули тренутно очитавање на екрану. Притисните поново да бисте отпустили.
• МИНМАКС: Press the MINMAX button to activate recording. The meter will display the maximum, minimum, and average readings sequentially. Press again to cycle through Min, Max, Avg. Hold the button to exit.
• ДОМЕТ: In auto-ranging modes, the meter automatically selects the best range. Press RANGE to switch to manual ranging. Each subsequent press will cycle through available ranges. Hold the button to return to auto-ranging.

7. Одржавање
