4.2 Поврзување на тест кабли

1. Вметнете го црниот мерен кабел во влезниот приклучок „COM“ (Заеднички).
2. Вметнете ја црвената мерна сонда во соодветниот влезен приклучок за вашето мерење:
   • За волtage, resistance, capacitance, frequency, diode, and continuity measurements, insert the red lead into the 'VΩHz' jack.
   • For current measurements (mA/A), insert the red lead into the 'mA/A' jack.

4.3 Вклучување/исклучување

Press and hold the power button to turn the multimeter on or off. The device may also feature an auto-power-off function to conserve battery life.

5. Упатства за работа

The FS899L features auto-ranging, simplifying operation by automatically selecting the correct measurement range. Use the function buttons to select the desired measurement mode.

5.1 Режими на мерење

• Voltage Мерење (AC/DC): Изберете го томtage mode. Connect the test leads in parallel to the circuit or component to measure voltage.
• Мерење на струја (AC/DC): Select the current mode. Connect the multimeter in series with the circuit to measure current. Ensure the correct input jack is used for current.
• Мерење на отпор: Select the resistance mode. Ensure the circuit is de-energized before measuring resistance. Connect the leads across the component.
• Мерење на капацитетот: Select the capacitance mode. Ensure capacitors are discharged before testing.
• Мерење на фреквенција: Select the frequency mode to measure the frequency of an AC signal.
• Мерење на температурата: The multimeter can measure ambient temperature.
• NCV (Без-контакт томtagд) Детекција: Use this feature to detect the presence of AC voltagд без директен контакт.
• Мерење на диодата: Test diodes for proper function.
• Тест за континуитет: The on/off buzzer indicates continuity (low resistance).
• Live Line Identification: For identifying live wires.

6. Одржување

6.1 Чистење

Wipe the multimeter's casing со рекламаamp крпа. Не користете абразивни средства за чистење или растворувачи. Пред чистење, проверете дали уредот е исклучен од струја и исклучен од сите струјни кола.

6.2 Грижа за батерии

To maintain battery health, charge the multimeter regularly, especially if it will not be used for an extended period. Avoid fully discharging the battery frequently.

6.3 Замена на осигурувачите

The FS899L is designed with double-fuse protection. If the multimeter fails to measure current or shows incorrect current readings, the fuse may need replacement. Refer to a qualified technician for fuse replacement to ensure proper fuse type and rating are used.

6.4 Складирање

Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures. Disconnect test leads when storing.

7 Смена на проблеми

• Нема екран/уред што не се вклучува:
  • Ensure the battery is charged. Connect the multimeter to a USB charger for at least 30 minutes.
  • Притиснете и држете го копчето за вклучување цврсто.
• Неточни читања:
  • Verify test leads are correctly inserted into the appropriate input jacks for the selected measurement mode.
  • Check that the test leads are not damaged.
  • Ensure the circuit is properly connected and de-energized for resistance/capacitance measurements.
  • For current measurements, check the fuse.
