Иштөө нускамалары
1. Battery Charge Level Test
This test measures the open-circuit voltage of the battery to determine its state of charge.
- Ensure the tester is correctly connected to the battery as described in the "Setup" section.
- Томду окуңузtage displayed on the digital screen.
- Refer to the following table for approximate charge levels:
| Тtage (12V Battery) | Болжолдуу заряд |
|---|---|
| 12.70 V же андан жогору | 100% |
| 12.40 V | 75% |
| 12.20 V | 50% |
| 12.00 V | 25% |
| Below 12.00 V | Бошогон |
2. Battery Starting Capacity (Load) Test
This test simulates the load on the battery during engine cranking to assess its ability to deliver high current.
- Сыноочу батареяга туташып турганын текшериңиз.
- Press and hold the "STOP" button (or equivalent load switch) for approximately 10 seconds. The tester will apply a 250A discharge.
- Томду байкаңызtage reading on the digital display during the load test.
- A healthy battery should maintain a voltage above 9.6V during the 10-second load test. If the voltage drops significantly below this, the battery's starting capacity is weak and may need replacement.
- Release the button after 10 seconds. Allow the battery to rest for a few minutes before retesting or performing other tests.
3. Alternator Function Test
This test verifies if the vehicle's alternator is properly charging the battery.
- With the F-814 connected to the battery, start the vehicle's engine.
- Let the engine idle. The voltage reading on the tester should be between 13.8V and 14.7V.
- Turn on various electrical loads (headlights, fan, radio, etc.) and observe the voltagд. Томtage should remain within the healthy range.
- Эгерде томtage is consistently below 13.8V (undercharging) or above 14.7V (overcharging), there may be an issue with the alternator or voltage жөнгө салуучу.
Техникалык тейлөө
The FERVE F-814 battery tester requires minimal maintenance.
- Ар бир колдонгондон кийин, тестерди аарчып, тазалаңызamps with a clean, dry cloth to remove any dirt, grease, or battery acid residue.

Проблемаларды чечүү
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Tester display does not light up. | Incorrect connection; Battery completely discharged; Damaged cables/clamps. | Полярдуулуктун тууралыгын (+ дан + га, - дан - га чейин) текшериңиз. Батареянын кубаттуулугун текшериңизtage with a multimeter (if possible). Inspect cables for damage. |
| Так эмес томtagэ окуулар. | Poor connection to battery terminals; Corroded battery terminals. | Камсыз кылуу clamps are securely attached. Clean battery terminals thoroughly. |
| Тtage drops too quickly during load test. | Алсыз же иштебей калган батарея. | Battery may need charging or replacement. Consult a professional if unsure. |
| Alternator test shows incorrect voltage. | Faulty alternator or voltage regulator; Loose alternator belt. | Have the vehicle's charging system inspected by a qualified mechanic. |
