4. Орнотуу

4.1 DC Power Supply (SPS-3010) Setup

1. Жайгашкан жери: Place the power supply on a stable, level surface with adequate ventilation. Ensure cooling fan vents are not obstructed.
2. Кубат туташуу: Connect the supplied AC power cord to the AC Power Inlet (16) on the rear panel and plug it into a grounded wall outlet.
3. Чыгуу туташуулары: Connect your load to the Output Terminals: Red (+) to positive, Black (-) to negative. The Green (GND) terminal is for chassis ground.
4. Баштапкы күйгүзүү: Ensure Voltage and Current knobs are set to minimum before turning on the Power Switch (14).

4.2 Digital Oscilloscope (JDS210) Setup

1. Жайгашкан жери: Place the oscilloscope on a stable, flat surface.
2. Кубат туташуу: Connect the supplied power adapter to the oscilloscope's power input and then to a power outlet.
3. Зонд туташуу: Connect the oscilloscope probes to the CH1 or CH2 BNC input connectors. Ensure the probe's attenuation setting (e.g., 1X, 10X) matches the oscilloscope's probe setting. The oscilloscope supports 1X/10X/100X/1000X probes.
4. Зонддун компенсациясы: Before taking measurements, compensate your probes. Connect the probe to CH1 and the probe tip to the probe compensation output (usually a small terminal near the BNC inputs). Adjust the probe until a perfect square wave is displayed.

5. Иштөө нускамалары

5.1 DC Power Supply (SPS-3010) Operation

1. Күйгүзүү: Press the Power Switch (14). The LED display will illuminate.
2. Setting Voltage: Томду колдонуңузtage Coarse (6) and Fine (8) knobs to set the desired output voltagд. The Voltage Display (1) shows the current setting.
3. Учурдагы чектөөнү коюу: Use the Current Coarse (7) and Fine (9) knobs to set the maximum output current. This acts as a current limit to protect your circuit. The Current Display (2) shows the current limit.
4. Constant Voltage (C.V.) and Constant Current (C.C.) Modes:
   • When the load resistance is high, the power supply operates in C.V. mode (Constant Voltage), indicated by the C.V. Mode Indicator (4). The output voltage remains constant at the set value.
   • When the load resistance is low, causing the current to reach the set limit, the power supply automatically switches to C.C. mode (Constant Current), indicated by the C.C. Mode Indicator (5). The output current remains constant at the set limit, and the voltage тамчы.
5. USB кубаттоо функциясы: The 5V/2A USB Charging Port (10) can be used to charge compatible devices. This port provides a fixed 5V output at up to 2A, independent of the main output settings.

3. Канал тандоо: Use the CH1 and CH2 buttons to enable or disable channels.
4. Vertical Scaling (Voltagд): Use the 'Scale' knob for each channel (V/Div) to adjust the vertical sensitivity. The 'Position' knob moves the waveform vertically.
5. Horizontal Scaling (Time): Use the 'Scale' knob (s/Div) to adjust the time base. The 'Position' knob moves the waveform horizontally.
6. Иштетүүдө: Adjust the 'Trigger' level knob to stabilize the waveform. The trigger mode can be set via the menu.
7. Өлчөөлөр: Use the 'Measure' button to access automatic measurements (e.g., Vpp, Vrms, Frequency). Use the 'Cursor' button to enable manual cursors for precise voltage (ΔV) and time (ΔT) measurements.

6. Техникалык тейлөө

• Тазалоо: Disconnect power before cleaning. Use a soft, dry cloth to clean the exterior. Do not use abrasive cleaners or solvents.
• Вентиляция: Regularly check that the cooling vents on both devices are clear of dust and debris. Use compressed air if necessary to clear dust from the fan and vents.
• Сактагыч: Түзмөктөрдү күн нурунан жана экстремалдык температурадан алыс салкын, кургак жерде сактаңыз.
• Fuse Replacement (SPS-3010): If the power supply does not turn on, check the fuse located in the Fuse Box (17) on the rear panel. Replace with a fuse of the same type and rating if blown. A spare fuse is typically included inside the fuse box.

7. Кыйынчылыктарды

If you encounter issues with your Jesverty devices, refer to the following common problems and solutions:

• Кубат жок:
  • Check if the power cord is securely connected to the device and the wall outlet.
  • Verify the wall outlet has power.
  • For SPS-3010, check and replace the fuse if necessary (refer to Maintenance section).
• SPS-3010 Output Voltage/Current Not Stable or Zero:
  • Ensure output terminals are correctly connected to the load.
  • Check if the current limit is set too low for the load. Increase the current limit using the current knobs.
  • If in C.C. mode, the voltage will drop to maintain the set current. This is normal operation.
• JDS210 No Waveform or Unstable Waveform:
  • Ensure probes are correctly connected to the oscilloscope and the circuit under test.
  • Check probe compensation.
  • Adjust vertical (V/Div) and horizontal (s/Div) scales.
  • Adjust the trigger level or use the 'Auto' button.
  • Verify the input signal is within the oscilloscope's measurement range.
• Дисплей маселелери:
  • If the display is blank or distorted, power cycle the device.
  • Ашыкча ысып кетүүнүн алдын алуу үчүн туура желдетүүнү камсыз кылыңыз.
