Description
EXFO Maxtester 720D Repair
The EXFO Maxtester 720D is a cable certifier – it certifies installed cabling against a standard, which means its verdict becomes a deliverable someone else relies on. It works as a main and remote pair, and both units plus the adapters they test through carry the accuracy.
Certified technicians at June Company service the EXFO Maxtester 720D for network installers, structured cabling contractors, and certification teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common EXFO Maxtester 720D problems we fix
- Insertion loss or crosstalk measurement inaccurate.
- Test port or connector damage.
- Length and delay measurement errors.
- Display, keypad or front-panel faults.
- Battery or charging faults.
- GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
- Test adapter worn – a consumable interface whose wear produces failures indistinguishable from genuinely faulty cabling.
- Main and remote not pairing or not agreeing.
