The IRD Mechanalysis 810SA is a handheld vibration‑spike energy detector used for condition monitoring of rotating machinery. Common failures on this model include loss of signal due to damaged accelerometer wiring or connector corrosion, power supply dropout (battery or external adapter), and firmware corruption that causes the unit to display “NO DATA” or erratic spike readings. The device also frequently exhibits calibration drift if not periodically verified against a known standard.

First‑check diagnostics: verify battery voltage and secure all cable connectors; inspect the accelerometer housing for physical damage or moisture ingress; review any error codes on the display and cross‑reference with the operation manual’s troubleshooting table. If power and wiring are sound, run a calibration check using a calibrated vibration source to confirm sensor accuracy.[oss-gpt-20b]
