1. Uvod

The PCE Instruments PCE-LT 15 is a versatile combination device functioning as both a digital multimeter (DMM) and a LAN cable tester. It is designed for accurate measurement of AC/DC voltage and resistance, as well as for performing continuity and diode tests. Additionally, it features a dedicated function for testing LAN cables and patch fields, providing pin-out indication for network cable integrity.

2. Sigurnosne informacije

Before operating the PCE-LT 15, please read and understand all safety instructions. Improper use can result in electric shock, injury, or damage to the device. Always adhere to local and national safety regulations.

• električna sigurnost: This device is rated for CAT III 600V. Do not attempt to measure voltages exceeding this rating.
• Rukovanje sondom: Always ensure test leads are in good condition, free from cracks or damage. Hold probes by the insulated parts.
• Isključivanje strujnog kola: Before performing resistance or continuity tests, ensure the circuit under test is de-energized.
• Sigurnost baterije: Replace batteries when the low battery indicator appears. Do not mix old and new batteries or different battery types. Dispose of batteries according to local regulations.
• Uslovi okoline: Do not operate the device in wet conditions or in the presence of explosive gases or dust.

• Test kablovi: Red and black leads for multimeter measurements.
• Digitalni prikaz: Shows measurement values for multimeter functions.
• LED Pin-Out Indicator: Displays the status of each wire in a LAN cable.
• Rotacijski prekidač funkcija: Selects measurement modes (AC/DC Voltage, Resistance, Continuity, OFF).
• Kontrolna dugmad: SEL (Select), RNG (Range), HOLD (Data Hold), ON/OFF (LAN Tester).

4. Podešavanje

4.1. Instalacija baterije

The PCE-LT 15 requires two types of batteries:

• Multimeter Function: 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. Povezivanje ispitnih vodova

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. Uputstvo za upotrebu

5.1. Uključivanje / isključivanje napajanja

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 Voltage Measurement

1. Okrenite rotacijski prekidač na 'V~' (AC Voltage) ili 'V=' (DC Voltage) position. The device is auto-ranging.
2. Connect the test leads in parallel to the circuit or component where voltage treba izmjeriti.
3. Pročitajte voltage vrijednost prikazana na LCD-u.

5.3. Mjerenje otpora

1. Ensure the circuit or component is de-energized before measurement.
2. Okrenite rotacijski prekidač u položaj 'Ω' (Otpor).
3. Spojite mjerne kablove preko komponente koju treba mjeriti.
4. Očitajte vrijednost otpora prikazanu na LCD ekranu.

5.4. Test kontinuiteta

1. Osigurajte da je strujni krug ili komponenta bez napona.
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. Spojite mjerne kabele preko strujnog kola ili komponente.
4. If the measured resistance is less than approximately 25Ω, the device will emit an audible alarm, indicating continuity.

5.5. Test diode

1. Provjerite je li dioda isključena iz bilo kojeg izvora napajanja.
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. Spojite crveni mjerni kabel na anodu, a crni na katodu diode. Naporni volt...tage drop će se prikazati.
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. Održavanje

6.1. Čišćenje

Obrišite uređaj suhom, mekom krpom. Ne koristite abrazivna sredstva za čišćenje ili rastvarače. Pazite da vlaga ne uđe u uređaj.

6.2. Zamjena baterije

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. Skladištenje

Kada se uređaj ne koristi duži period, izvadite baterije kako biste spriječili curenje. Čuvajte uređaj na hladnom i suhom mjestu, dalje od direktne sunčeve svjetlosti i ekstremnih temperatura.

7. Otkrivanje problema

• Nema ekrana/uređaj se ne uključuje: Provjerite ugradnju baterija i osigurajte da su baterije dovoljno napunjene. Zamijenite ih ako je potrebno.
• Netačna očitanja: 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.
