5.2. Bandymo laidų prijungimas

Tinkamas bandymo laidų prijungimas yra labai svarbus norint atlikti tikslius ir saugius matavimus.

• Įkiškite juodą bandymo laidą į „COM“ (bendrosios) įvesties lizdą.
• Daugumai tūriųtage, resistance, continuity, diode, and frequency measurements, insert the red test lead into the "VΩHz%" input jack.
• For current measurements (mA/µA), insert the red test lead into the "mAµA" input jack.
• For higher current measurements (A), insert the red test lead into the "A" input jack.

6. Naudojimo instrukcijos

6.1. Įjungimas/Išjungimas

Rotate the central function dial from the "OFF" position to any desired measurement function to turn on the multimeter. To turn off, rotate the dial back to the "OFF" position.

6.2. Funkcijos pasirinkimas

The large rotary dial is used to select the desired measurement function. Press the "SEL" button to cycle through sub-functions within a single dial position (e.g., AC/DC voltage, varža / tęstinumas / diodas).

6.3. Matavimo režimai

Below are common measurement modes and their applications:

• ttagMatavimas (V~ / V-):

  Select V~ for AC voltage or V- for DC voltage. Connect test leads in parallel with the circuit or component to be measured. Ensure the red lead is in the VΩHz% jack.
• Current Measurement (mAµA / A):

  Select the appropriate current range (mAµA or A). Connect the multimeter in series with the circuit. Ensure the red lead is in the corresponding mAµA or A jack. Atsargiai: Never connect the multimeter in parallel for current measurement, as this can damage the device or blow the fuse.

• Varžos matavimas (Ω):

  Select the Ω function. Ensure the circuit is de-energized before measuring resistance. Connect test leads across the component.

• Continuity Test (audible beep symbol):

  Select the continuity function. The multimeter will emit an audible beep if the resistance between the probes is below a certain threshold, indicating continuity.
• Diode Test (diode symbol):

  Select the diode function. Use to test the forward voltagdiodo lašas.

• Dažnio matavimas (Hz):

  Select the Hz function. Measures the frequency of an AC signal.

• Capacitance Measurement (capacitance symbol):

  Select the capacitance function. Measures the capacitance of a capacitor. Ensure the capacitor is fully discharged before testing.
• Nekontaktinis ttage (NCV):

  Select the NCV function. Hold the top of the multimeter near a live AC voltage source. The device will beep and the NCV indicator will light up if voltagaptinkamas e.

• LoZ (Low Impedance) Measurement:

  This function helps to detect and eliminate ghost voltages. Refer to the display for the LoZ indicator.
