  2. Za večino meritev (Voltage, Resistance, Continuity, Diode, Frequency, Duty Cycle), insert the red test lead into the "VΩHz" input jack.
  3. Ensure test leads are fully inserted before taking measurements.

6. Navodila za uporabo

The MS8301D uses a rotary switch to select the primary measurement function and function buttons for secondary selections or features.

6.1 Splošno delovanje

  • Vklop/izklop: Rotate the function switch from "OFF" to any desired measurement function to turn on the meter. Rotate back to "OFF" to power off. The meter also features Auto Power Off.
  • Osvetlitev ozadja: Press the backlight button (often labeled with a light bulb icon) to illuminate the display.
  • Zadrževanje podatkov: Pritisnite gumb »HOLD«, da zamrznete trenutno odčitavanje na zaslonu. Za sprostitev pritisnite znova.
  • MAX/MIN: Press the "MAX/MIN" button to enter MAX/MIN recording mode. The meter will display the maximum or minimum value detected. Press again to cycle through MAX, MIN, and current readings.

6.2 Merilne funkcije

Always ensure the correct function is selected and test leads are connected to the appropriate input jacks before making measurements.

  1. DC Voltage Measurement (V DC):
    • Rotate the switch to the "V" position. The meter will automatically select DC or AC. If needed, press the "FUNC" button to select DC.
