7.2 Batiri Rirọpo

When the low battery indicator appears on the display, replace the 9V battery as described in Section 5.1. Using a low battery can lead to inaccurate readings.

7.3 Fiusi Rirọpo

If the current measurement function stops working, the fuse may need replacement. This should only be performed by qualified personnel. The internal fuses are F250mA/250V and F10A/250V.

8. Laasigbotitusita

• No Display / Power On Issue: Check battery installation and charge. Replace battery if necessary.
• "OL" Ti a fihan:
  • In resistance mode: Indicates an open circuit or resistance beyond the meter's range.
  • In diode mode (reverse bias): Normal for a good diode.
  • In current mode: Indicates current exceeding the selected range. Switch to a higher range (e.g., 10A jack) or check for an open circuit.
• Awọn kika ti ko pe:
  • Ṣayẹwo ipele batiri.
  • Ensure test leads are fully inserted and not damaged.
  • Verify the correct function and range are selected.
• Ko si Beep Tesiwaju: Ensure the continuity function is selected (speaker icon on display). Check if the circuit resistance is above 100Ω.
