1. Ifihan

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. Alaye Aabo

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.

• Aabo Itanna: This device is rated for CAT III 600V. Do not attempt to measure voltages exceeding this rating.
• Ìmúlò Ìwádìí: Always ensure test leads are in good condition, free from cracks or damage. Hold probes by the insulated parts.
• Circuit De-energization: Before performing resistance or continuity tests, ensure the circuit under test is de-energized.
• Aabo Batiri: 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.
• Awọn ipo Ayika: Do not operate the device in wet conditions or in the presence of explosive gases or dust.

4.1. Fifi sori batiri

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. Nsopọ Awọn itọsọna Igbeyewo

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.

3. So awọn itọsọna idanwo kọja Circuit tabi paati.
4. If the measured resistance is less than approximately 25Ω, the device will emit an audible alarm, indicating continuity.

5.5. Diode igbeyewo

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. So asiwaju idanwo pupa mọ anode ati asiwaju idanwo dudu mọ katode ti diode naa. A forward vol.tage silẹ yoo han.
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).
