4. Упутство за употребу

Before operating, ensure the multimeter is in good condition and the test leads are properly connected. Always select the appropriate function and range before making a measurement.

4.1. Укључивање/искључивање

Rotate the rotary switch from the "OFF" position to any desired measurement function to power on the device. To power off, rotate the switch back to the "OFF" position. The device also features an automatic shut-down function after 15 minutes of inactivity.

4.2. АЦ/ДЦ ВолtagМерење (V~)

1. Set the rotary switch to the "V~" position for AC voltage or "V-" for DC voltage.
2. Повежите мерне каблове паралелно са колом или компонентом која се тестира.
3. Прочитајте књtagе вредност на дисплеју.

4.3. V.F.C. Variable Frequency Voltagе Мерење

Током АЦ волtage measurement, press the "V.F.C." button to activate the variable frequency voltage measurement mode. This is useful for measuring voltage in circuits with variable frequency drives.

4.4. Мерење отпора (Ω)

1. Set the rotary switch to the "Ω" position.
2. Пре мерења отпора, уверите се да је коло без напона.
3. Повежите мерне каблове преко компоненте.
4. Очитајте вредност отпора на дисплеју.

4.5. Capacitance Measurement (mF)

1. Set the rotary switch to the "mF" position.
2. Уверите се да је кондензатор потпуно испражњен пре мерења како бисте спречили оштећење мултиметра.
3. Спојите мерне каблове преко кондензаторских терминала.
4. Очитајте вредност капацитивности на екрану.

4.6. НЦВ (Нон-Цонтацт Волtage) Measurement

1. Поставите ротациони прекидач у положај "NCV".
2. Move the top end of the multimeter close to the AC voltagизвор (нпр. жица под напоном или утичница).
3. Уређај ће указивати на присуство AC вол.tage through an audible beep and visual indicator (green for weak signal, red for strong signal).

Figure 4.3: The multimeter performing an NCV (Non-Contact Voltage) test. The display shows "--L" for a weak current signal (green indicator) and "--H" for a strong current signal (red indicator and buzzer alarm).

Figure 4.4: The multimeter's NCV function in use, detecting a live wire in an electrical outlet. The display shows "LIVE" indicating the presence of AC voltage.

4.7. Мерење температуре (°C/°F)

1. Set the rotary switch to the "Temp" position.
2. Connect the temperature probe (K-type thermocouple) to the appropriate input jacks.
3. Поставите врх сонде на или близу објекта чија температура треба да се мери.
4. Очитајте вредност температуре на дисплеју.

Note: The complimentary temperature probe can only measure up to 300°C. For higher temperatures, a professional temperature probe is required.

4.8. Функција чувања података

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

4.9. Backlight and Flashlight

Press the backlight/flashlight button to turn on the display backlight for better visibility in dim conditions. Press and hold the button to activate the built-in flashlight.

4.10. Auto/Manual Range

The multimeter supports both auto-ranging and manual ranging. In auto-range mode, the meter automatically selects the best range for the measurement. Press the "RANGE" or "SEL" button (depending on model) to switch to manual ranging and cycle through available ranges.

5. Одржавање

5.1. Чишћење

Обришите кућиште огласомamp cloth and mild detergent. Do not use abrasives or solvents. Keep the input terminals clean and free from dust or debris.

5.2. Замена батерије

When the battery indicator appears on the display, replace the batteries immediately to ensure accurate readings. Refer to section 3.2 for battery installation instructions.

5.3. Замена осигурача

If the multimeter fails to measure current or shows an "FUSE" indicator, the fuse may be blown. Refer to the internal diagram for fuse specifications and replace with a fuse of the same type and rating. Always disconnect test leads and power off the device before opening the case.
