Ingiza Kitufe: Confirms selections or entered values.
Kitufe cha WEKA: Enters parameter setting mode.
Kitufe cha MENU: Accesses the main menu for configuration and advanced settings.
OPERATE Button: Toggles the output on or off.
Kitufe cha DISPLAY: Cycles through different display modes or views.

3.2 Operesheni ya Msingi

Kuweka Voltage na ya sasa:
- Bonyeza kwa WEKA kitufe.
- 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.
- Bonyeza INGIA ili kuthibitisha mpangilio.
Kuwezesha Pato:
- Once parameters are set, press the ENDESHA button to enable the power output. The output indicator should illuminate.
- To disable the output, press ENDESHA tena.
Masomo ya Ufuatiliaji:
The display continuously shows the actual output voltage and current. Use the ONYESHA button to cycle through different measurement views if available.

4. Matengenezo

Kusafisha: Keep the instrument clean by wiping the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the unit is powered off and disconnected from the AC supply before cleaning.
Uingizaji hewa: Periodically check that the ventilation grilles are free from dust and debris to ensure proper airflow and prevent overheating.
Hifadhi: When not in use for extended periods, store the instrument in a clean, dry environment within its specified operating temperature and humidity ranges.
Urekebishaji: 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. Utatuzi wa shida

Tatizo	Sababu inayowezekana	Suluhisho
Ala haiwashi.	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.
Hakuna pato voltage / sasa.	Output disabled; incorrect settings; overload protection active; faulty connections.	Bonyeza ENDESHA 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.
Kuzidisha joto.	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.
