- Эсептегич өчүрүлгөнүн текшериңиз.
- Батарея уясынын капкагын эсептегичтин арткы жагында табыңыз.
- Батарея отсегин ачуу үчүн бурагычты колдонуңуз.
- Үч AAA батарейкасын бөлүмдүн ичинде көрсөтүлгөндөй туура полярдуулукка (+/-) сактоо менен салыңыз.
- Батарея уясынын капкагын ордуна коюңуз жана аны бурама менен бекитиңиз.
5.2 Сыноо өткөргүчтөрүн туташтыруу
Том үчүнtage, resistance, capacitance, frequency (from test terminal), continuity, and diode measurements, connect the test leads:
- Кызыл сыноочу зымын 'INPUT' уячасына киргизиңиз.
- Кара сыноочу зымын 'COM' (жалпы) уячага киргизиңиз.
6. Иштөө нускамалары
6.1 Функциялык тергич
Каалаган өлчөө функциясын тандоо үчүн борбордук дөңгөлөктү айландырыңыз:
- ӨЧҮК: Эсептегичти өчүрөт.
- V~: AC Voltage өлчөө.
- V-: DC Voltage өлчөө.
- A~: AC Current measurement (using clamp).
- TO-: DC Current measurement (using clamp).
- Ω K Å: Resistance, Continuity, Diode, Capacitance measurement. Use the 'SEL' button to cycle through these functions.
- Гц%: Жыштыкты жана жумуш циклин өлчөө.
6.2 Баскыч функциялары
- SEL (Yellow Button): Selects sub-functions within a main dial position (e.g., AC/DC, Ohm/Diode/Continuity).
- MIN / MAX: Toggles between minimum and maximum recorded values during a measurement session.
- чуркап барып: Toggles between auto-ranging and manual ranging. In manual range, press repeatedly to cycle through ranges.
- Гц/%: When in Voltage or Current mode, press to display frequency or duty cycle.
- B.L. HOLD: Short press to activate/deactivate data hold (freezes the current reading). Long press (2 seconds) to turn the backlight ON/OFF.
