Jinko JK2511 DC Low Resistance Tester User Manual

1. Киришүү

The Jinko JK2511 DC Low Resistance Tester is an intelligent instrument designed for precise measurement of low DC resistance. It offers a wide measurement range and high precision, making it suitable for various industrial applications. This tester is ideal for measuring the copper resistance of transformer and inductor windings, contact resistance of relays and switches, resistance of wire connectors, solder contact resistance of components, and resistance of PCB lines and vias. Its capabilities extend to metal detection and integration into production lines, where it can output good/bad product signals via HANDLER or optional GPIB interfaces to enhance automated testing.

4. Орнотуу

1. Пакеттен чыгаруу: Carefully remove the JK2511 tester from its packaging. Inspect for any signs of damage during transit. Retain the packaging for future storage or shipping.
2. Кубат туташуу: Connect the provided power cord to the instrument's power input and then to a grounded AC power outlet. Ensure the voltage matches the instrument's requirements.
3. Зонд туташуу: Connect the test probes to the appropriate input terminals on the front panel. Typically, these are labeled SENSE+, SENSE-, DRIVE+, and DRIVE-. Ensure a secure connection for accurate measurements.
4. Баштапкы күйгүзүү: Press the red POWER button on the front panel to turn on the instrument. The display should illuminate, indicating the device is operational.
5. Өзүн-өзү сыноо: The instrument may perform a brief self-test upon startup. Wait for this process to complete before proceeding with measurements.

5.1 Негизги өлчөө

1. DUT туташтыруу: Connect the Device Under Test (DUT) to the test probes. Ensure good contact between the probes and the measurement points on the DUT.
2. Select Measurement Range: The JK2511 typically auto-ranges. If manual range selection is available, use the appropriate buttons (e.g., SETUP or navigation keys) to select a range suitable for the expected resistance value.
3. Өлчөөнү баштоо: The instrument usually displays the resistance value continuously. For a stable reading, press the БЕРҮҮ button to freeze the display.
4. Дисплейди окуу: Observe the resistance value shown on the digital display, along with the corresponding unit (mΩ, Ω, or kΩ).

5.2 Advanced Features (If Applicable)

• Limit Testing (HIGH/PASS/LOW): The instrument supports setting upper and lower resistance limits. Use the ЖАЙГАШУУ menu to configure these limits. The ЖОГОРКУ, PASS, жана АЗ indicators will illuminate to show if the measured resistance falls above, within, or below the set limits.
• Дайындарды кармоо: басыңыз БЕРҮҮ button to freeze the current measurement on the display. Press it again to release and resume continuous measurement.
• Нөлдөө функциясы: For highly accurate low resistance measurements, a zeroing function may be available to compensate for test lead resistance. Consult the full manual for specific instructions on performing a zero adjustment.
• Interface Communication: For automated testing, connect the instrument to a PC or PLC via the HANDLER interface or optional GPIB interface. Refer to the communication protocol documentation for programming details.

6. Техникалык тейлөө

• Тазалоо: Disconnect power before cleaning. Use a soft, dry cloth to wipe the exterior of the instrument. Do not use abrasive cleaners or solvents.
• Пробка кам көрүү: Keep test probes clean and free from corrosion. Replace damaged probes immediately to ensure accurate measurements and safety.
• Сактагыч: When not in use, store the instrument in a clean, dry environment, away from direct sunlight and extreme temperatures.
• Калибрлөө: Өлчөөнүн тактыгын сактоо үчүн, айрыкча маанилүү колдонмолор үчүн, квалификациялуу персонал тарабынан үзгүлтүксүз калибрлөө сунушталат.

7. Кыйынчылыктарды

This section provides solutions to common issues. For problems not listed here, contact Jinko customer support.

• Түзмөк күйбөйт:
  • Check if the power cord is securely connected to both the instrument and the power outlet.
  • Электр розеткасынын иштешин текшериңиз.
  • Check the instrument's fuse, if accessible and user-replaceable (refer to the full manual).
• Туура эмес же туруксуз көрсөткүчтөр:
  • Ensure test probes are making good, clean contact with the DUT.
  • Check for damaged or worn test leads.
  • Verify that the DUT is properly isolated and not influenced by external electrical noise.
  • Perform a zero adjustment if available.
  • Consider if the instrument requires calibration.
• Display shows "OVERLOAD" or "OL":
  • The measured resistance may be higher than the selected range. If auto-ranging, this indicates the resistance is beyond the instrument's maximum capability.
  • Check for open circuits in the DUT or test leads.
