2. Безбедносне информације

WARNING: To avoid electric shock or personal injury, always follow basic safety precautions when using this instrument.

  • Увек се уверите да су мерни каблови у добром стању и правилно повезани.
  • Не покушавајте да мерите волtages or currents exceeding the maximum rated values for each range.
  • Always turn off power to the circuit under test before connecting or disconnecting test leads.
  • Будите опрезни када радите са вол.tages above 30V AC RMS, 42V peak, or 60V DC, as they pose a shock hazard.
  • Replace the battery and fuse only with the specified types.
  • Do not operate the multimeter if it appears damaged or if the case is open.

  4. ЦОМ улазни прикључак: Common/Negative (-) input for all measurements.
  5. OHMS Adjustment Knob: Used to zero the meter for resistance measurements.
  6. Battery Test Sockets: Dedicated sockets for testing 1.5V and 9V batteries.

4. Подешавање

4.1 Инсталација батерије

The Woods AMMW1 requires 1 AA battery (included) for operation. To install or replace the battery:

  1. Ensure the multimeter is turned off (selector switch to OFF position, if available, or a non-measurement range).
  2. Пронађите поклопац одељка за батерије на задњој страни уређаја.
  3. Remove the screw(s) securing the cover and carefully open it.
  4. Insert the AA battery, observing the correct polarity (+ and - markings).
  5. Вратите поклопац и причврстите га завртњем (завртњима).

4.2 Повезивање мерних каблова

  • Уметните црни тест кабл у ЦОМ (Обични) џек.
  • Уметните црвени тест кабл у ВΩмА jack for most measurements (voltage, resistance, current).

5. Упутство за употребу

Before taking any measurement, ensure the test leads are correctly connected and the rotary selector is set to the appropriate function and range.

5.1 Меасуринг ДЦ Волtagе (В-)

  1. Set the rotary selector to the desired DC Voltage (V-) range (e.g., 2.5V, 10V, 50V, 250V, 500V). Choose a range higher than the expected voltage.
  2. Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side.
  3. Прочитајте књtage value from the appropriate DCV scale on the analog display.

5.2 Меасуринг АЦ Волtagе (В~)

  1. Set the rotary selector to the desired AC Voltage (V~) range (e.g., 10V, 50V, 250V, 500V). Choose a range higher than the expected voltage.
  2. Спојите мерне каблове преко AC волтаtagе извор.
  3. Прочитајте књtage value from the appropriate ACV scale on the analog display.

5.3 Мерење отпора (Ω)

  1. Set the rotary selector to the desired Resistance (Ω) range (e.g., 10x Ω, 1000x Ω).
  2. Short the red and black test leads together.
  3. Подесите OHMS ADJUST knob until the needle points exactly to '0' on the OHMS scale. This zeros the meter.
  4. Connect the test leads across the component whose resistance you wish to measure. Ensure the component is de-energized.
  5. Read the value from the OHMS scale and multiply it by the range multiplier (e.g., x10, x1000).

5.4 Measuring DC Current (mA, µA)

  1. УПОЗОРЕЊЕ: Never connect the multimeter in parallel with a voltage source when measuring current. Always connect it in series with the circuit.
  2. Set the rotary selector to the desired DC Current (mA or µA) range (e.g., 500 µA, 10 mA, 250 mA).
  3. Break the circuit where you want to measure current.
  4. Connect the multimeter in series with the circuit, ensuring the red lead is towards the higher potential and the black lead towards the lower potential.
  5. Read the current value from the appropriate scale.

5.5 Battery Testing (1.5V, 9V)

  1. Set the rotary selector to the 1.5V BATT or 9V BATT положај.
  2. Insert the battery to be tested into the corresponding battery test sockets, observing polarity.
  3. Read the battery condition from the dedicated "BAD / GOOD" scale on the analog display.

6. Одржавање

6.1 Чишћење

Обришите кућиште огласомamp крпу и благи детерџент. Не користите абразивна средства или раствараче. Држите мерне каблове чистим и без остатака.

6.2 Замена осигурача

The multimeter is equipped with fuse and diode protection. If the current measurement function stops working, the fuse may need replacement.

  1. Уверите се да је мултиметар искључен и да су мерни каблови одспојени.
  2. Open the back cover of the multimeter (refer to battery installation).
  3. Пажљиво уклоните стари осигурач.
  4. Replace with a fuse of the exact same type and rating (consult the device's internal markings or specifications for fuse type).
  5. Сигурно затворите задњи поклопац.
