1. Prijunkite bandymo laidus prie kintamosios srovės įtampostage šaltinis.
2. Rotate the dial to the "V~" position. The analyser will auto-range.
3. Ekrane bus rodomas AC voltage.

4.5. DC Current Measurement (ADC)

Measures direct current flow.

1. Svarbu: To measure current, the analyser must be connected in series with the circuit. Ensure the circuit is de-energized before connecting.
2. For measurements up to 400mA, connect the red lead to "VΩmA" and the black lead to "COM". For measurements up to 10A, connect the red lead to "10A" and the black lead to "COM".
3. Rotate the dial to the "A-" position.
4. Apply power to the circuit. The display will show the DC current.

4.6. AC Current Measurement (AAC)

Measures alternating current flow.

1. Svarbu: Connect the analyser in series with the circuit. Ensure the circuit is de-energized before connecting.
2. For measurements up to 400mA, connect the red lead to "VΩmA" and the black lead to "COM". For measurements up to 10A, connect the red lead to "10A" and the black lead to "COM".
3. Rotate the dial to the "A~" position.
4. Apply power to the circuit. The display will show the AC current.

4.7. Resistance, Continuity, and Diode Test (Ω)

This position on the dial allows for measuring resistance, checking circuit continuity, and testing diodes. Ensure the circuit or component is de-energized before performing these tests.

When the low battery indicator appears on the display, replace the batteries immediately to ensure accurate readings. Refer to the battery compartment cover for instructions on accessing and replacing the batteries (typically 9V battery).

5.3. Sandėliavimas

Store the analyser in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.

6. Problemų sprendimas

• Nėra ekrano / įrenginys neįsijungia:
  • Check if the function dial is set to an "ON" position.
  • Patikrinkite baterijų įdėjimą ir įkrovos lygį. Jei reikia, pakeiskite baterijas.
• Erratic RPM Readings:
  • Ensure the inductive coupler is securely clipped around the spark plug lead.
  • Try repositioning the inductive coupler closer to the spark plug.
  • Verify the correct engine type (2-stroke/4-stroke) and RPM range (x1/x10) are selected using the "DIS" button.
  • Some spark plug leads or caps may interfere with inductive pickup. Experiment with different leads if possible.
• "OL" (Overload) or "OPEN" Display:
  • The measured value exceeds the selected range. If in manual range mode, select a higher range. If in auto-ranging, this indicates an open circuit or a value beyond the analyser's maximum capability.
  • For continuity/diode tests, "OL" indicates an open circuit or a reverse-biased diode.
• Netikslūs rodmenys:
  • Check battery level. Low batteries can affect accuracy.
  • Įsitikinkite, kad bandymo laidai yra tinkamai prijungti ir nepažeisti.
  • Verify the correct function and range are selected for the measurement.
  • Ensure the component or circuit is isolated if required (e.g., for resistance, diode, capacitance).
