NAN. Depanaj

• No reading or unstable reading: Check battery levels and replace if necessary. Ensure test leads are securely connected and not damaged. Verify the rotary switch is set to the correct function and range.
• Incorrect resistance reading: Perform Ohm adjustment (zeroing) as described in Section 6.5. Ensure the component being tested is de-energized.
• Mezi aktyèl la pa fonksyone: Check the fuse(s) and replace if blown (refer to Section 8.3). Ensure the meter is connected in series with the circuit.
• Needle not moving: Ensure the meter is powered on (if applicable for specific functions) and the test leads are making good contact.

10. Konsèy itilizatè yo

• Always start with the highest range: Lè w ap mezire yon vol enkonitage or current, always start with the highest range setting and then decrease it until you get a suitable reading. This prevents overloading the meter.
• Zero Ohm adjustment: Remember to perform the Ohm adjustment (zeroing) every time you change the resistance range for accurate readings.
• Observe polarity: For DC measurements, observing polarity is important. If the needle deflects backward, reverse the test leads.
• Analog vs. Digital: Analog multimeters are great for observing trends and fluctuating signals, as the needle movement can show changes more dynamically than a digital display.
