Cable Autotest

Press (Cable Autotest) to measure cable length, detect split pairs, and/or perform a wiremap test. The Network Assistant does not measure cable length when it detects a link pulse (i.e., when connected to an active device such as a Hub).

The Network Assistant also starts the fiber tests automatically if a DSP-FOM is connected and turned on

when you press (Autotest). Read “Test Fiber Optic Cable” later in this chapter.

Split Pairs

The Network Assistant automatically checks for split pairs whenever Autotest or Cable Autotest is run. It will not check for split pairs if the end of the cable is attached to a Hub, a cable identifier, or the internal Wiremap connection. Disconnect it to obtain a complete test.

Note

The cable under test must be longer than 20 feet.

The Network Assistant can identify split pairs that occur either at the connector or at an intermediate point, such as a punchdown block.

Cable Length Results

When displaying cable length, the Network Assistant always reports the length to the first fault (e.g., opens, shorts, or split pairs). It shows the distance to the fault and to the end of the cable on the same pair as illustrated in the following example test results table.

Pair

135 ft

Open

 

3,6

91 ft

4,5

7,8

91 ft

Split Pair

In the case of pairs 3,6 and 7,8 there is a split pair at 91 feet and it is most likely that both pairs continue for the entire cable length of 135 feet.

A split pair at the connector is represented as Split/Open? with a length of less than 5 feet (1.5 m). A Split/Open? indication could also be an open at the indicated distance.

Wiremap Cable

The Wiremap Cable test verifies pin-to-pin continuity from the near to the far end of the cable, making it easy to identify miswires (the most common installation problem) and other wiring errors.

Series II specifications

The Fluke Series II is a cutting-edge line of industrial multimeters that incorporates advanced technology and features tailored for professionals working in critical environments. Renowned for their precision and reliability, these multimeters are quintessential tools for technicians and engineers alike, whether in manufacturing, electrical engineering, or maintenance applications.

One of the hallmark characteristics of the Fluke Series II is its robust design. Constructed to endure harsh working conditions, these meters come equipped with a high-impact casing that protects against drops and vibrations. Their IP67 rating ensures they are dust-tight and can withstand temporary immersion in water, making them ideal for fieldwork in tough environments.

The Series II boasts a range of measurement capabilities. With the ability to measure voltage, current, and resistance, as well as additional readings such as frequency, capacitance, and temperature, these multimeters deliver unparalleled versatility. Many models in the Series II also feature True RMS (Root Mean Square) measurement capabilities, enabling accurate readings of non-linear and distorted waveforms, which are increasingly common in modern electronics.

Another significant feature is the advanced display technology. The Series II multimeters often come with large, high-contrast LCDs that facilitate easy reading in various lighting conditions. Some models even offer graphical displays, enabling users to visualize trends in measurement data over time.

User-friendliness is also a hallmark of the Fluke Series II. With intuitive interfaces and simplified navigation, users can access advanced features quickly. Auto-ranging capabilities allow the meter to automatically select the appropriate range for the measurement, minimizing user errors and streamlining the testing process.

Fluke's commitment to safety is underscored by the design of the Series II, which includes features such as safety-rated test leads, protective rubber booting, and a high-voltage warning indicator for added peace of mind.

Moreover, the connectivity options within the Series II enable seamless data transfer to PCs and mobile devices, facilitating easier logging and analysis of measurement data. Many models support Bluetooth or USB connectivity, making it easier than ever to integrate multimeter readings into existing data collection and analysis workflows.

In conclusion, the Fluke Series II multimeters stand out for their durability, versatility, and user-centric features. Their combination of advanced measurement technology, rugged design, and safety functions makes them essential instruments for professionals who demand accuracy and reliability in their work. The commitment to innovation and excellence that Fluke exemplifies ensures that the Series II remains a trusted choice in the field of industrial measurement tools.
