Description
Fluke Ti401 PRO Infrared Camera Repair
The Fluke Ti401 PRO is a Professional-series imager with LaserSharp auto-focus – it uses a laser distance measurement to focus precisely on the target rather than estimating, which is what makes its temperature readings trustworthy at distance. The laser, the focus drive and the measurement chain are therefore tied together in a way they are not on manual-focus models.
June Company repairs and calibrates the Fluke Ti401 PRO for thermographers, predictive maintenance programs, electrical contractors, and industrial inspection teams. Every imager is repaired at component level and its temperature accuracy verified against reference standards before it ships back, with the measured results documented.
Common Fluke Ti401 PRO problems we fix
- Battery will not hold charge or unit will not power on – the pack, the charging circuit and the power section, tested separately.
- LaserSharp auto-focus not locking – the laser distance measurement and the focus drive, which fail together often enough that both are tested as one system.
- Out-of-focus images producing wrong temperatures – the specific danger on this model – a soft image does not just look bad, it reports incorrect readings.
- Dead pixels or fixed pattern noise – microbolometer detector faults, which show as permanent spots or a grid pattern that no amount of re-focusing clears.
- Image degrading between shutter cycles – the internal NUC shutter, which recalibrates the detector every few minutes – when it sticks the image drifts and blotches until the unit is power-cycled.
- Temperature readings drifted – the measurement path rather than the image – a picture that looks fine can still be reporting the wrong number.
- Visible-light camera or IR-Fusion faults.
- Wireless or data transfer failures.
- Display or touchscreen failure.
FAQs
How long does a repair take? Most are completed in 5-10 business days, with a firm quote after evaluation and before any work starts.
Auto-focus stopped working – can I just focus manually instead? You can, but the temperature accuracy this model is bought for depends on correct focus, so it is worth repairing rather than working around.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
