Cable faults are one of the leading causes of network faults. Fluke Networks provides three types of testers: verifiers, qualifiers, and certifiers. Each test device is ideal for a specific purpose. The verifiers test for continuity, qualifiers check whether a connection works at a certain speed, whereas the certifiers are used to test for compliance with a specific cable standard.
This guide covers details about the different testers, their respective target audience, and the process of selecting a proper tester.
How to Choose a Fluke Tester Class?
There are three types of testers, which are priced and designed for their own purposes. Verifiers are used for quick fault testing, qualifiers test network and Power over Ethernet (PoE), and certifiers generate test results based on standards. Below is a list of three present-day testers:
| Class | Model | Best use |
| Verifier | MicroScanner2 | Wiremap, length, distance to fault, cable ID |
| Qualifier | LinkIQ | Cable checks plus PoE and switch identification |
| Certifier | Versiv DSX | Copper certification at IEC Level V accuracy |
When Does a Verifier Work Best?
Fluke Networks MicroScanner2 is geared towards daily troubleshooting where efficiency takes precedence over report creation. The product performs many tests all at once through the same interface. The following are its major advantages:
- Wiremap, pair length, distance to fault, and far-end device are shown simultaneously.
- PoE class determination from 0 to 8 and power switch identification.
- IntelliTone toning to locate and verify copper cabling.
- Distance-to-fault measurement of up to 1,500 feet.
When Is a Qualifier or Certifier Needed?
Qualifiers are ideal for network teams that need to verify whether a connection is carrying live data. LinkIQ is the successor to CableIQ and introduced PoE and switch detection capabilities. Certifiers are appropriate for contractual work since reporting may be required for the acceptance of warranty claims. The Versiv tester by Fluke Networks allows for remote configuration and job tracking through LinkWare Live.
How Should Buyers Decide?
The right tool is dependent on the deliverables expected from your clients. A contractor requiring certified reports requires different tools from a technician troubleshooting issues on a live network. Requirements like fiber testing, PoE load testing and certification make it easy to narrow down the list. A list of Fluke Networks’ products will be useful provided it passes these tests:
- For fault finding alone: A MicroScanner2 Verifier provides wiremap, length, and distance to fault simultaneously.
- For network and PoE validation: LinkIQ adds PoE and switch validation features.
- Testing fiber optic losses: Includes CertiFiber Pro modules to the Versiv series.
- Reporting through the cloud: Select devices compatible with LinkWare Live.
Final Thoughts
Selection of a tester depends entirely on the task at hand. Verifiers help in quick fault detection, qualifiers check the preparedness of the network, and certifiers provide proof of compliance. Make sure to review the latest specification of a product on the manufacturer’s website prior to buying, as the models and prices differ. A clear match between tool and task shortens troubleshooting and improves the quality of every installation.
