Fluke Cable Cable for use with USB-IR

The Fluke RS_493-5540 is a dedicated USB-IR (infrared) interface cable designed to connect compatible Fluke test instruments, such as portables, scopes or power-quality analysers with optical-isolation IR ports, directly to a PC USB port. It enables data transfer, logging and reporting without needing special serial adapters, making it convenient for engineers and technicians working on-site or in offices.

Advanced Features and Benefits of Buying the Fluke Cable for USB-IR

• The cable provides a secure, optically-isolated link between the instrument’s USB-IR port and a standard PC USB interface, allowing floating instruments to connect safely even when attached to live systems.
• Works with a range of Fluke devices across series, including 190 and other supported ScopeMeter or data-logging models.
• Supports reliable data communication over lengths typical for field use (cable length ~1.5 m according to distributor specs), making work easier when the instrument and PC cannot be placed side-by-side.
• Backwards-compatible with legacy PC operating systems and common data-logging software, simplifying integration into existing workflows.

Why Professionals Choose this Cable

For field technicians, service engineers, or maintenance teams, the RS_493-5540 enhances data handling with convenience and accuracy. Instead of manually copying readings, a process prone to human error, the cable automates data transfer. It is particularly valuable during audits, preventive-maintenance cycles, or whenever long-term data logging is required.

Application Potential of the Cable

• Transferring measurement logs from ScopeMeter or power-quality analysers to PCs after field measurements.
• Uploading recorded data from maintenance visits for trending, analysis, and reporting.
• Data-logging tasks in industrial plants, electrical contractors, and facility maintenance, where accurate record-keeping is necessary.
• Situations where instruments must remain connected to live systems, but data must be safely exported to a computer.
