Engineering Advantages
Multi-Protocol Network Diagnostics
The 1788-MCHKR simplifies field maintenance by supporting a wide array of legacy and modern industrial networks. Technicians can use a single device to troubleshoot Ethernet (UTP/FTP), ControlNet (RG6/RG6F), DeviceNet (Thick/Thin), and legacy DH+/RIO cables. This versatility eliminates the need to carry multiple specialized testers, reducing toolbag weight and streamlining troubleshooting workflows.
Precise Cable Fault Detection and Length Measurement
This media checker accurately detects common cable failures such as opens, shorts, and miswires. It provides precise length measurements with a 0.5-meter resolution for Ethernet cables up to 350 meters and ControlNet cables up to 650 meters. Knowing the exact location of a fault or the total length of a cable run helps engineers quickly replace damaged sections and verify compliance with network physical layer specifications.
Rugged Portable Design
Designed for the demanding industrial environment, the 1788-MCHKR operates reliably in temperatures ranging from 0°C to 45°C. Its handheld form factor and intuitive interface—featuring Enter, Up, Down, and Setup buttons alongside a clear 16-character LCD—allow technicians to perform rapid wire mapping and continuity tests directly on the factory floor without needing a laptop or external power source.
FAQs
Q: Which types of industrial cables can the 1788-MCHKR test?
A: This media checker supports a broad range of cables. It tests Ethernet (UTP/FTP), ControlNet (RG6, RG6F, DS3/4), DeviceNet (Thick, Thin, KwikLink), and legacy DH+/RIO cables (1770-CD, 9022, 9463).
Q: How accurate is the cable length measurement?
