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. Складиштење

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.

КСНУМКС. Решавање проблема

• No Display/Unit Not Powering On:
  • Check if the function dial is set to an "ON" position.
  • Verify battery installation and charge level. Replace batteries if necessary.
• 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.
• Нетачна очитавања:
  • Check battery level. Low batteries can affect accuracy.
  • Ensure test leads are properly connected and not damaged.
  • 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).
