"This is insane," Elias whispered. He was a salvage man. He fixed things. He didn't unmake things.

| | Likely Cause | Solution (from manual) | |-------------|------------------|-----------------------------| | No display, no backlight | Dead or incorrectly inserted batteries | Replace 3 x AAA batteries. Check polarity. | | Display shows “OL” | Overload or out of range | Switch to a higher range (if manual-ranging) or check if input exceeds 600V/10A. | | Inaccurate voltage reading | Weak batteries (low battery icon appears) | Replace batteries. Low battery affects reference voltage. | | No continuity beep | Wrong mode (resistance instead of continuity) | Press MODE until buzzer appears. | | Fuse blows frequently | Measuring voltage with leads in current jacks | Replace fuse (0.5A/600V or 10A/600V). Always return red lead to VΩ jack. | | Fluctuating readings on AC | Non-sinusoidal waveform or interference | Use REL to null noise. Ensure leads are twisted. | zm-7205a manual
