4. Орнотуу
4.1. Батареяны орнотуу
The Sanwa AP-33 requires one AAA (R03) 1.5V battery. The battery is typically included and pre-installed. If replacement is needed:
- Ensure the multimeter is OFF and test leads are disconnected.
- Аппараттын артындагы батарея бөлүкчөсүнүн капкагын табыңыз.
- Open the cover and insert the AAA battery, observing correct polarity (+/-).
- Батарея уясынын капкагын бекем жабыңыз.
4.2. Test Lead Connection and Storage
The test leads are permanently attached to the main unit and can be wound around the integrated lead holder for storage. The pin tip metal part length can be adjusted by attaching or detaching the cylindrical cap.

5. Иштөө нускамалары
Before any measurement, ensure the meter's pointer is at zero. Use the Meter Zero Adjuster if necessary. For resistance measurements, short the test leads and use the 0Ω Adjuster to set the pointer to zero on the resistance scale.
Сүрөт 5.1: Жакын пландан view of the analog scale for reading measurements.
5.1. DC Voltage (DCV)
- Set the dial switch to the desired DCV range (10V, 50V, 250V, or 500V). Choose a range higher than the expected voltage.
- Кызыл сыноо зымын чынжырдын оң (+) тарабына, ал эми кара сыноо зымын терс (-) тарабына туташтырыңыз.
- Томду окуңузtage value on the appropriate DCV scale.
5.2. Өлчөө AC Voltage (ACV)
- Set the dial switch to the desired ACV range (50V, 250V, or 500V). Choose a range higher than the expected voltage.
- Сыноо өткөргүчтөрүн AC том аркылуу туташтырыңызtage source. Polarity does not matter for AC voltage.
- Томду окуңузtage value on the appropriate ACV scale.
5.3. Measuring DC Current (DCmA)
WARNING: Never connect the multimeter in parallel with a voltage source when measuring current. This can blow the fuse or damage the meter.
- Set the dial switch to the desired DCmA range (25mA or 250mA).
- Open the circuit where current is to be measured.
- 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.
- Read the current value on the appropriate DCmA scale.
5.4. Каршылыкты өлчөө (Ω)
- Set the dial switch to the desired Ω range (x10 or x1k).
- Before measuring, short the test leads together and use the 0Ω Adjuster to set the pointer to zero on the resistance scale.
- Connect the test leads across the component whose resistance is to be measured. Ensure the component is de-energized.
- Read the resistance value on the Ω scale and multiply by the range factor (x10 or x1k).
5.5. Battery Check (BATT)
- Set the dial switch to the BATT position (1.5V or 9V).
- Кызыл сыноо өткөргүчтү аккумулятордун оң (+) терминалына жана кара сынагын терс (-) терминалына туташтырыңыз.
- Read the battery condition on the 'BAD ? GOOD' scale.
6. Техникалык тейлөө
6.1. Тазалоо
Эсептегичти кургак, жумшак чүпүрөк менен сүртүңүз. Абразивдерди же эриткичтерди колдонбоңуз.

Refer to Section 4.1 for battery replacement instructions. Always replace with a fresh AAA (R03) 1.5V battery.
6.3. Сактагычты алмаштыруу
The multimeter contains a built-in fuse (0.5A 250V, φ5×20mm, breaking capacity 35A) for current protection. If the current measurement function fails, the fuse may need replacement. Fuse replacement should only be performed by qualified personnel.
6.4. Сактоо
Узак убакыт бою колдонулбаган учурда, агып кетпеши үчүн батареяны алып салыңыз. Мультиметрди салкын, кургак жерде, күндүн түз нурунан жана өтө жогорку температурадан алыс сактаңыз.
7. Кыйынчылыктарды
- No reading / Meter not turning on: Check battery installation and ensure the battery is not depleted. Replace if necessary.
- Incorrect reading: Ensure the correct function and range are selected. Verify test lead connections. Perform zero adjustment for resistance.
- Токту өлчөө иштебей жатат: Check the internal fuse. If blown, replace with a fuse of the same rating.
- Pointer not at zero: Use the Meter Zero Adjuster (for voltage/current) or 0Ω Adjuster (for resistance) to calibrate.
