Fluke 1653B Installation Tester Repair
The Fluke 1653B is a multifunction installation tester – loop impedance, RCD trip timing, continuity, insulation and earth resistance in one instrument, used to certify that a fixed installation is safe. The results go on a certificate, which raises the stakes on accuracy considerably.
June Company repairs and calibrates the Fluke 1653B for electrical contractors, installation inspectors, testing and certification bodies, and maintenance electricians. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Fluke 1653B problems we fix
- Loop impedance readings drifted.
- Continuity or low-resistance measurement errors.
- Insulation test voltage low or absent.
- Test lead compensation not holding zero.
- Output or measurement drifted out of tolerance – corrected and verified against reference standards.
- Battery, charging or power faults.
- Display, keypad or interface faults.
- RCD trip timing inaccurate – the measurement most directly tied to safety certification, and one that fails without any obvious symptom.
FAQs
Do you service instruments past manufacturer support? Yes. Much of what we repair is out of support, which is exactly where component-level work earns its keep.
These results go on certificates. How is accuracy documented? Verified against reference standards, with the measured results returned with the instrument – which is what certification work requires.
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.
