4. Настройка

4.1. Устаноўка батарэі

The PCE-LT 15 requires two types of batteries:

• Функцыя мультыметра: Requires 2 x 1.5V AAA batteries. Open the battery compartment on the main unit, insert batteries with correct polarity, and secure the cover.
• LAN Tester Function: Requires 1 x 9V 6F22 battery. Open the battery compartment on the main unit, insert the battery with correct polarity, and secure the cover.

Ensure batteries are correctly installed before use. Replace batteries when the low battery indicator appears on the display.

4.2. Падключэнне вымяральных правадоў

For multimeter functions, insert the red test lead into the 'VΩmA' input jack and the black test lead into the 'COM' (common) input jack. Ensure connections are secure.

5. Інструкцыя па эксплуатацыі

5.1. Уключэнне / выключэнне харчавання

The multimeter function powers on when the rotary switch is moved from the 'OFF' position to any measurement function. To power off the multimeter, turn the rotary switch to 'OFF'. The LAN tester has a separate 'ON/OFF' button.

5.2. AC/DC Voltagе Вымярэнне

1. Павярніце паваротны перамыкач у становішча «V~» (AC Voltage) або 'V=' (DC Voltage) position. The device is auto-ranging.
2. Connect the test leads in parallel to the circuit or component where voltage падлягае вымярэнню.
3. Прачытайце тtagзначэнне, якое адлюстроўваецца на ВК-дысплеі.

5.3. Вымярэнне супраціву

1. Ensure the circuit or component is de-energized before measurement.
2. Павярніце паваротны перамыкач у становішча «Ω» (супраціўленне).
3. Падключыце вымяральныя дроты да кампанента, які трэба вымераць.
4. Read the resistance value displayed on the LCD.

5.4. Тэст бесперапыннасці

1. Пераканайцеся, што ланцуг або кампанент абясточаны.
2. Turn the rotary switch to the 'Ω' position, then press the 'SEL' button to cycle to the continuity mode (indicated by a buzzer icon).
3. Падключыце вымяральныя дроты да ланцуга або кампанента.
4. If the measured resistance is less than approximately 25Ω, the device will emit an audible alarm, indicating continuity.

5.5. Тэст дыёда

1. Ensure the diode is disconnected from any power source.
2. Turn the rotary switch to the 'Ω' position, then press the 'SEL' button to cycle to the diode test mode (indicated by a diode symbol).
3. Connect the red test lead to the anode and the black test lead to the cathode of the diode. A forward voltagбудзе адлюстравана кропля.
4. Reverse the test leads. An open circuit (OL) reading indicates a good diode.

5.6. LAN Cable Testing

1. Connect one end of the LAN cable to the RJ45 port on the main unit.
2. Connect the other end of the LAN cable to the RJ45 port on the remote unit.
3. Press the 'ON/OFF' button for the LAN Cable Tester.
4. Press the 'TEST' button to initiate the cable test.
5. Observe the 'PIN-OUT INDICATOR' LEDs (1-8, GND) on the main unit. The LEDs will sequentially light up, indicating the continuity and correct wiring of each pin. Any missing or incorrectly lit LEDs indicate a fault (e.g., open, short, cross-over).

6. Тэхнічнае абслугоўванне

6.1. Уборка

Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.

6.2. Замена батарэі

Replace batteries promptly when the low battery indicator is displayed to ensure accurate measurements and prevent device malfunction. Refer to Section 4.1 for battery installation instructions.

6.3. Захоўванне

Калі прылада не выкарыстоўваецца працяглы час, выміце батарэйкі, каб прадухіліць уцечку. Захоўвайце яе ў прахалодным, сухім месцы, удалечыні ад прамых сонечных прамянёў і экстрэмальных тэмператур.

7. Выпраўленне непаладак

• Няма дысплея/прылада не ўключаецца: Праверце ўстаноўку акумулятараў і пераканайцеся, што яны дастаткова зараджаныя. Пры неабходнасці замяніце.
• Няправільныя паказанні: Ensure test leads are properly connected and not damaged. Verify the correct measurement function is selected. Check battery level.
• 'OL' (Overload) Indicator: This indicates the measured value exceeds the selected range. For auto-ranging, it means the value is beyond the device's maximum capability for that function.
• LAN Test Failure: Check both ends of the LAN cable for proper connection to the main and remote units. Inspect the cable for physical damage. Ensure the LAN tester batteries are charged.
