The Acu‑Rite Qwikcount II is a dual‑axis digital position readout (DRO) used on machine tools and coordinate measuring machines; it comprises a console with solid‑state electronics and one or more scale assemblies that detect table movement. Common failure modes include loss of display or signal, erratic axis readings, and intermittent power to the DRO unit—often caused by degraded power supply capacitors, burnt input/output contacts, or worn scale bearings. First‑check steps: verify 24 V DC supply voltage at the console terminals; inspect the input/output connectors for corrosion or broken pins; visually examine the scale assembly for mechanical damage or misalignment and confirm that the DRO’s internal fuse is intact.[oss-gpt-20b]
