4. Sozlash

4.1. Batareyani o'rnatish

The M70 requires 4 AA batteries (included). To install or replace batteries:

1. Ensure the meter is turned off and disconnect all test leads.
2. Hisoblagichning orqa tomonidagi batareya bo'linmasi qopqog'ini toping.
3. Mahkamlash vintini (vintlarini) oching va qopqoqni olib tashlang.
4. To'g'ri qutblanishni (+/-) kuzatib, 4 ta AA batareyasini joylashtiring.
5. Replace the cover and secure it with the screw(s).

4.2. Sinov simlarini ulash

Connect the test leads to the appropriate input jacks on the multimeter based on the measurement function you intend to use. For most measurements, the black lead connects to the 'COM' jack and the red lead connects to the 'VΩmA' or '10A' jack, as indicated by the function selected.

5. Foydalanish bo'yicha ko'rsatmalar

5.1. Quvvatni yoqish/o'chirish

To power on the M70, rotate the function switch from the 'OFF' position to the desired measurement function. To power off, rotate the switch back to 'OFF'.

5.2. Funktsiyani tanlash

The large rotary switch on the front panel allows you to select various measurement functions, including:

• jildtage (AC/DC)
• Tok (AC/DC)
• Qarshilik
• Davomiylik
• Diyot sinovi
• Imkoniyatlar
• Chastotasi
• Insulation Resistance (250V, 500V, 1000V)

5.3. Izolyatsiya qarshiligini o'lchash

The M70 offers insulation resistance testing at 250V, 500V, and 1000V. Follow these general steps:

1. Ensure the circuit under test is completely de-energized and safely isolated.
2. Select the desired insulation test voltage (250V, 500V, or 1000V) using the rotary switch.
3. Connect the test leads to the appropriate terminals of the device or circuit to be tested.
4. Press and hold the 'TEST' button to initiate the insulation test. The test voltage qo'llaniladi.
5. Ekranda ko'rsatilgan izolyatsiya qarshiligi qiymatini o'qing.
6. Release the 'TEST' button to stop the test. The circuit will be discharged.
7. Always wait for the discharge to complete before disconnecting the test leads.

6. Xizmat ko'rsatish

6.1. Tozalash

Hisoblagich korpusini reklama bilan artib olingamp mato va yumshoq yuvish vositasi. Aşındırıcılar yoki erituvchilardan foydalanmang. Ishlatishdan oldin hisoblagich to'liq quruqligiga ishonch hosil qiling.

6.2. Batareyani almashtirish

When the battery indicator appears on the display, replace the batteries as described in Section 4.1. Remove batteries if the meter is not used for extended periods to prevent leakage.

7. Muammolarni bartaraf qilish; nosozliklarni TUZATISH

• Displey yo'q: Batareyaning o'rnatilishini va zaryadlanishini tekshiring. Agar kerak bo'lsa, batareyalarni almashtiring.
• Noto'g'ri o'qishlar: Ensure test leads are correctly connected, the function switch is set to the appropriate measurement, and the circuit under test is properly prepared.
• Meter Does Not Respond: Hisoblagichni o'chiring va keyin yana yoqing. Muammo davom etsa, batareyalarni chiqarib oling va qayta joylashtiring.
• Insulation Test Fails: Verify the circuit is de-energized. Check test lead connections. Ensure the 'TEST' button is held down firmly.
