Model: 2303-PJ
1. Tuote ohiview
The Keithley 2303-PJ is a specialized power supply designed for testing portable, battery-operated devices. It offers advanced capabilities to simulate a battery's performance across a wide range of conditions, including output resistance and voltage response. This instrument is crucial for accurately testing device charge control circuitry and overall battery simulation.
Keskeisiä ominaisuuksia ovat:
- Ultra-fast response to transient load currents
- Variable output resistance
- 100nA DC current sensitivity
Figure 1: Front panel of the Keithley 2303-PJ Power Supply. The display shows voltage and current readings (e.g., 3.60V, 1.08A). Controls include a navigation pad, 'DISPLAY', 'MENU', 'OPERATE', 'ENTER', 'SET' buttons, and a 'POWER' button with indicator lights.
2. Asennus
- Purkaminen ja tarkastus: Carefully remove the instrument from its packaging. Inspect for any signs of damage during transit. Report any damage to the shipping carrier and Keithley immediately.
- Virtaliitäntä: Connect the supplied AC power cord to the instrument's rear panel power inlet and then to a grounded AC power outlet. Ensure the power source matches the instrument's voltage vaatimukset.
- Ensimmäinen käynnistys: Paina POWER button located on the front panel. The display should illuminate, indicating the unit is operational.
- Connecting to Device Under Test (DUT): Use appropriate test leads to connect the output terminals of the 2303-PJ to the device you intend to test. Observe correct polarity.
- Ilmanvaihto: Ensure adequate ventilation around the instrument. Do not block the ventilation grilles on the sides or rear of the unit.
3. Käyttöohjeet
3.1 Etupaneelin säätimet
- Näyttö: Näyttää lähtöäänenvoimakkuudentage, current, and other operational parameters.
- Navigointipainikkeet (ylös, alas, vasemmalle, oikealle): Käytetään valikoissa navigointiin ja parametrien arvojen säätämiseen.
- ENTER -painike: Confirms selections or entered values.
- SET -painike: Siirtyy parametrien asetustilaan.
- MENU-painike: Accesses the main menu for configuration and advanced settings.
- OPERATE Button: Toggles the output on or off.
- NÄYTTÖ-painike: Cycles through different display modes or views.
3.2 Peruskäyttö
- Asetus Voltage ja nykyinen:
- Paina SARJA -painiketta.
- Use the navigation buttons to select the voltage or current parameter you wish to adjust.
- Use the navigation buttons (typically Up/Down) to change the value.
- Paina ENTER vahvistaaksesi asetuksen.
- Lähdön käyttöönotto:
- Once parameters are set, press the KÄYTTÖ button to enable the power output. The output indicator should illuminate.
- To disable the output, press KÄYTTÖ uudelleen.
- Lukemien seuranta:
The display continuously shows the actual output voltage and current. Use the NÄYTTÖ button to cycle through different measurement views, jos saatavilla.
4. Huolto
- Puhdistus: Keep the instrument clean by wiping the exterior with a soft, damp liinalla. Älä käytä hankaavia puhdistusaineita tai liuottimia. Varmista, että laite on sammutettu ja irrotettu verkkovirrasta ennen puhdistamista.
- Ilmanvaihto: Periodically check that the ventilation grilles are free from dust and debris to ensure proper airflow and prevent overheating.
- Varastointi: When not in use for extended periods, store the instrument in a clean, dry environment within its specified operating temperature and humidity ranges.
- Kalibrointi: For optimal performance and accuracy, periodic calibration by qualified personnel is recommended. Refer to the Keithley service manual or contact Keithley support for calibration procedures and intervals.
5. Vianmääritys
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Laite ei käynnisty. | No AC power; faulty power cord; internal fuse blown. | Check AC power connection and outlet. Try a different power cord. If fuse is suspected, contact qualified service personnel. |
| Ei lähtöä voltage/nykyinen. | Output disabled; incorrect settings; overload protection active; faulty connections. | Paina KÄYTTÖ to enable output. Verify voltage/current settings. Check for short circuits or overloads on the DUT. Ensure test leads are securely connected. |
| Unstable or inaccurate readings. | Poor connections; external interference; instrument needs calibration. | Check all connections for looseness or corrosion. Ensure the instrument is away from strong electromagnetic fields. Consider professional calibration. |
| Ylikuumeneminen. | Blocked ventilation; excessive ambient temperature; continuous operation at maximum load. | Ensure ventilation grilles are clear. Operate in a cooler environment. Reduce load or allow for cool-down periods. |
For issues not listed here or if troubleshooting steps do not resolve the problem, please contact Keithley technical support.
