4. Подешавање

4.1 Инсталација батерије

The meter requires batteries for operation. To install or replace batteries:

  1. Ensure the meter is OFF and disconnect any test leads.
  2. Пронађите поклопац одељка за батерије на задњој страни мерача.
  3. Одврните завртањ (завртње) за причвршћивање и скините поклопац.
  4. Уметните нове батерије, водећи рачуна о исправном поларитету (+ и -).
  5. Вратите поклопац одељка за батерије и причврстите га завртњем (завртњима).

Note: The meter features auto power off to conserve battery life.

5. Упутство за употребу

Before taking any measurements, ensure the meter is in good condition and the test leads are properly connected (if applicable).

5.1 Measuring AC Current (Clamp функција)

This function allows non-contact measurement of AC current up to 400A.

  1. Turn the function dial to the desired AC current range (2A, 20A, 200A, or 400A).
  2. Притисните цлamp trigger to open the clamp вилица.
  3. Enclose a single conductor (not a bundle of wires) within the clamp вилица. Уверите се да је вилица потпуно затворена.
  4. Очитајте вредност наизменичне струје на ЛЦД екрану.

Note: For accurate readings, ensure only one conductor is inside the clamp вилица.

5.2 Мерење АЦ/ДЦ Волtage

The meter measures AC/DC voltagе до 600В.

  1. Insert the black test lead into the COM jack and the red test lead into the V·Ω jack.
  2. Turn the function dial to the VDC or VAC position.
  3. If measuring DC voltage, press the MODE button to select DC if necessary.
  4. Повежите мерне сонде преко кола или компоненте коју треба мерити.
  5. Прочитајте књtagе вредност на ЛЦД екрану.

5.3 Мерење отпора (Ω)

Measures resistance in Ohms (Ω).

  1. Insert the black test lead into the COM jack and the red test lead into the V·Ω jack.
  2. Turn the function dial to the Ω position.
  3. Уверите се да је коло или компонента без напона пре мерења отпора.
  4. Повежите тест сонде преко компоненте.
  5. Очитајте вредност отпора на ЛЦД екрану.

5.4 Continuity and Diode Test

These functions are typically accessed via the Ω setting using the MODE button.

  1. Insert the black test lead into the COM jack and the red test lead into the V·Ω jack.
  2. Turn the function dial to the Ω position.
  3. Press the MODE button repeatedly until the continuity symbol (a speaker icon) or diode symbol (a triangle with a line) appears on the display.
  4. For continuity: Connect probes across the circuit. A continuous beep indicates a complete circuit.
  5. For diode: Connect probes across the diode. A forward bias voltage drop will be displayed. Reverse bias should show OL (open loop).

5.5 Measuring Frequency and Capacitance

The meter supports frequency and capacitance measurements, typically accessed through the V·Ω input and MODE button.

  1. Insert the black test lead into the COM jack and the red test lead into the V·Ω jack.
  2. Turn the function dial to the appropriate setting (often shared with voltage or resistance, requiring MODE selection).
  3. Press the MODE button until the frequency (Hz) or capacitance (F) symbol appears.
  4. Connect the test probes to the circuit or component.
  5. Очитајте вредност на ЛЦД екрану.

The meter includes a Type K thermometer for surface or air temperature measurements.

  1. Ensure the meter is OFF and disconnect any test leads.
  2. Insert the Type K thermocouple probe into the designated input jacks (usually marked with 'TEMP' or shared with V·Ω, check meter markings).
  3. Turn the function dial to the temperature setting (often marked with °C or °F).
  4. Поставите врх термопара на или близу објекта чија температура треба да се мери.

6.1 Чишћење

Обришите бројило огласомamp крпу и благи детерџент. Не користите абразивна средства или раствараче. Држитеamp вилица без прашине и остатака.

6.2 Замена батерије

Refer to Section 4.1 for battery installation/replacement instructions. Replace batteries when the low battery indicator appears on the display to ensure accurate readings.

6.3 Складиштење

If the meter is not used for an extended period, remove the batteries to prevent leakage. Store the meter in a cool, dry place away from direct sunlight.

КСНУМКС. Решавање проблема

Проблем Могући узрок Решење
Мерач се не укључује. Мртве или неправилно инсталиране батерије. Проверите поларитет батерија; замените батерије.
Приказано је „OL“ (преоптерећење). Мерење прелази изабрани опсег или максимални капацитет мерача. Select a higher range or ensure measurement is within meter's specifications.
Нетачна очитавања. Low battery, incorrect function/range, poor test lead connection, external interference. Replace batteries, verify function/range, ensure secure connections, move away from strong magnetic fields.
Нема очитавања за наизменичну струју. Више проводника у clamp jaw, DC current being measured. Ensure only one AC conductor is in the clamp. This meter measures AC current only.
