The Northen Telecom OPD352 is a vintage test set clock used in early industrial communication systems for time‑stamping and synchronization. Common failure modes on this model include degraded power supply rails, burnt-out oscillator components, and corrosion of the clock crystal contacts. First‑check steps: verify 12 V DC input with a multimeter, inspect the main PCB for burn marks or loose solder joints, and review any stored error logs for time‑base drift indications.[oss-gpt-20b] |
