For the 3300 XL series, the linear range is approximately 2.0 mm (80 mils). Ensure the probe tip is perpendicular to the shaft surface; an angled probe will result in a distorted scale factor and inaccurate vibration readings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHazardous Area Safety and Sealing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBecause this model (Option 28) carries multiple approvals, it is critical to use the provided M20 fittings and plugs (Option 03) according to local electrical codes.
