5.2. Zamjena baterije

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. Skladištenje

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. Otkrivanje problema

• Nema ekrana/Uređaj se ne uključuje:
  • Check if the function dial is set to an "ON" position.
  • Provjerite instalaciju baterija i nivo napunjenosti. Zamijenite baterije ako je potrebno.
• 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.
• Netačna očitavanja:
  • Check battery level. Low batteries can affect accuracy.
  • Provjerite da li su mjerni kablovi pravilno spojeni i da nisu oštećeni.
  • Provjerite da li su za mjerenje odabrani ispravna funkcija i raspon.
  • Ensure the component or circuit is isolated if required (e.g., for resistance, diode, capacitance).
