⚡ Easy DIY Troubleshooting & Common Fixes

🔧
The multimeter needle does not move or is stuck.
prob_01
Common root cause: Needle jammed due to impact or improper storage.
Step-by-step solution: With the multimeter off (selector on OFF or highest ACV/DCV setting), gently tap the side of the unit. If the needle frees up, check if it moves smoothly.
💡 Pro tip: Always store the multimeter with the selector on the highest voltage setting or OFF to protect the needle.
📸 Evidence to provide support: Short video (5s) showing the needle stuck when the unit is powered on.

⚙️ Hardware Setup, Adjustments & FAQs

❓ How do I zero the needle before use? cfg_01
For resistance measurements, use the 'Zero Ohm' (or similar) knob with the test leads shorted. For other measurements, the needle should be at zero on the scale when no signal is present.
