Parts Desk Insights
Best Use Case: Ideal for adding clear, at-a-glance tank level monitoring in tight dashboard or panel locations where a compact, daylight-readable OLED display is preferred.
Common Issues: If the display does not respond after installation, re-check polarity/wiring and confirm the sending unit resistance range matches the meter’s requirements; also verify the 1-1/8" cutout size and panel mounting orientation per the installation schematic.
