Quality Measurement Systems GM4 Dro for Comparator

The Quality Measurement Systems GM4 is a two‑axis digital readout (DRO) module designed to be mounted on optical comparators such as the Gage Master 29/GM4 series. Common failure modes include loss of signal from the DRO’s internal stepper drivers, drift or misalignment of the reference scale, and intermittent power supply to the microcontroller board; these often manifest as sudden zeroing, erratic readings, or a “no data” display. First‑check diagnostics: verify that the 12 V/5 V power rails are within spec and stable, inspect all connector pins for corrosion or loose contacts, and confirm that the DRO’s serial interface is transmitting correct data to the host PC (or monitor).[oss-gpt-20b]
