4. Подешавање
4.1 Инсталација батерије
- Уверите се да је мерач искључен из струје.
- Пронађите поклопац одељка за батерије на задњој страни мерача.
- Use a screwdriver to loosen the screw(s) and remove the cover.
- Insert the required batteries (typically AAA or 9V, refer to the compartment label) observing correct polarity.
- Вратите поклопац и причврстите га завртњем (завртњима).
4.2 Почетно укључивање
Turn the rotary switch to any measurement function to power on the meter. The LCD display will illuminate. To power off, turn the rotary switch to the 'OFF' position.
5. Упутство за употребу
This section details how to use the KPS-PF740 for various measurements.
5.1 Basic Measurement Modes
- АЦ/ДЦ Волtagе Мерење: Turn the rotary switch to the 'V~' or 'V=' position. Insert test leads into the appropriate input jacks. Connect the leads in parallel to the circuit under test.
- AC Current Measurement (Clamp): Turn the rotary switch to the 'A~' position. Open the clamp jaw and enclose a single conductor. Ensure the jaw is fully closed for accurate readings.
- Leakage Current Measurement: Turn the rotary switch to the 'mA~' position. Open the clamp jaw and enclose the conductor(s) where leakage current is to be measured. The meter offers high sensitivity for precise leakage detection.
- Мерење отпора: Turn the rotary switch to the 'Ω' position. Ensure the circuit is de-energized. Insert test leads and connect them across the component to be measured.
- Мерење капацитивности: Turn the rotary switch to the 'F' position. Ensure the capacitor is discharged before connecting test leads.
- Тест диода: Turn the rotary switch to the 'Diode' position. Connect the red lead to the anode and the black lead to the cathode of the diode.
- Тест континуитета: Turn the rotary switch to the 'Continuity' position. Connect test leads across the circuit. An audible tone indicates continuity.
- Мерење температуре: Turn the rotary switch to the '°C/°F' position. Connect the temperature probe to the input jacks.
5.2 Напредне функције
- Прави РМС: The meter automatically provides True RMS readings for AC measurements, ensuring accuracy for non-sinusoidal waveforms.
- Нископропусни филтер (ЛПФ): Activate the LPF function (if available via a button) to filter out high-frequency noise, useful for measurements on variable frequency drives.
- Подешавање нуле: For precise leakage current measurements, use the 'ZERO' button to nullify any residual readings before clampинг.
- MAX/MIN Recording: Press the 'MAX/MIN' button to capture the maximum and minimum values during a measurement session.
5.3 Приказ информација
The 4000-count LCD display shows measurement values, units, function indicators, and battery status. The meter features both automatic and manual ranging, which can typically be toggled with a 'RANGE' button.
6. Одржавање
6.1 Чишћење
Обришите ц бројилаasinг са огласомamp крпу и благи детерџент. Не користите абразивна средства или раствараче. Уверите се да је мерач сув пре складиштења или употребе.
6.2 Складиштење
When not in use for extended periods, remove the batteries to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
6.3 Замена батерије
Replace batteries when the low battery indicator appears on the display. Follow the battery installation steps outlined in Section 4.1.
