3.1 Таңгактан чыгаруу жана текшерүү

Carefully unpack the electronic load and its accessories. Verify that all components listed in the packing list are present and undamaged. If any items are missing or damaged, contact your supplier immediately.

3.2 Кубат туташтыруу

  1. Арткы панелдеги кубат которгучу ӨЧҮРҮҮ абалында экенин текшериңиз.
  2. AC киргизүү көлөмүн текшериңизtagАрткы панелдеги e тандоо которгучу жергиликтүү электр кубатынын үн деңгээлине дал келетtage (110V or 220V). Adjust if necessary.
  3. Connect the supplied AC power cord to the AC INPUT receptacle on the rear panel (refer to Figure 2.3).
  4. Кубат шнурунун экинчи учун жерге туташтырылган AC розеткасына сайыңыз.

3.3 Жүктөө Байланыш

Connect the device under test (DUT) to the input terminals on the front panel. Ensure correct polarity: connect the positive (+) terminal of the DUT to the positive (+) input of the electronic load, and the negative (-) terminal of the DUT to the negative (-) input of the electronic load.

For applications requiring high accuracy, especially with long connection cables, utilize the remote sensing terminals on the rear panel (refer to Figure 2.3). Connect the remote sensing wires directly to the DUT's output terminals to compensate for voltage drop across the load cables.

3.4 Байланыш интерфейстери

The MP71025B supports USB, RS232, and LAN communication. Connect the appropriate cable from the electronic load's rear panel to your computer or network device for remote control and data logging. Install the necessary drivers and software provided on the included CD or available from the manufacturer's webсайт.

4. Иштөө нускамалары

4.1 Негизги операция

  1. Turn on the power switch on the rear panel. The display will illuminate.
  2. басыңыз КҮЧ button on the front panel to activate the load.
  3. Select the desired operating mode (CC, CV, CR, CW) using the dedicated buttons on the front panel.
  4. Use the rotary encoders or the numeric keypad to set the desired load parameters (e.g., current in CC mode, voltage in CV mode).
  5. Басыңыз Кириңиз орнотууну ырастоо үчүн.

4.2 Иштөө режимдери

  • Туруктуу ток (ТК) режими: The load draws a constant current regardless of the input voltage. Ideal for battery discharge testing.
  • Constant Voltage (CV) режими: The load maintains a constant voltage across its terminals by adjusting the current drawn. Useful for power supply testing.
  • Constant Resistance (CR) Mode: The load simulates a constant resistance. The current drawn is proportional to the input voltage.
  • Constant Power (CW) Mode: The load draws a constant power, meaning the product of voltage and current remains constant.

4.3 Өркүндөтүлгөн функциялар

  • Батарея сыноо: Use this function to perform automated battery discharge tests. Refer to the detailed programming guide for setting up test parameters like discharge current, cut-off voltage, and duration.
