1. Safety Information

Safety Caution

This product complies with the safety requirement of EN 61010-1:2010.

This tester does not generate any hazardous voltages, and is designed to be used on de-energized circuits only. Connections to any main

supply voltage will result in damage to the tester and/or a hazard to the user. The user must assume responsibility for ensuring his, or her

own safety.

The BNC plug and socket are, by necessity, accessible. The outer sheath for this connector is always at SELV levels.

CAUTION

Do not connect to telephone networks or outside wiring. This will damage the NET200 and presents an electric shock hazard.

Verify that the system under test is de-energized before using the NET200.

Disconnect all cables from RJ45 and BNC connectors before charging or connecting to PC.

Check that all lead connections are correct before making a test.

Use only certified charger, please follow the user's manual. See Section 14.1

Refer to operating instructions for further explanation and precautions.

Safety warnings and Precautions must be read and understood before the instrument is used. They must be observed during use.

Any replacement battery pack must be fitted only by a Megger service centre. The battery must be disposed of according to local waste

directives. Do not dispose of the battery to landfill or incinerate it.

International Standards

 Safety

- IEC61010-1:2010

 EMC

- The equipment meets the European EMC directive 2004/108/EEC : and FCC47 Part 15(B) Class A

User’s manual for NET 200

- EN61326-1:2006, and EN61000-3-3:2008

 EMC

- This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules and

FCC47 CFRPart 15 Subpart B – Unintentional Radiators

EN61326:2006, CISPR11. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

2. Overview of Features

NET200 is an MTDR (Metallic Time-Domain Reflectometer) device that can measure the cable length and diagnose cable defects such as a

break (open), shorted-circuit and sudden change of impedance (such as, repeaters) in graphic and numeric formats. It also includes many

useful functions such as the Crosstalk test, Wiremap test and Network (TCP/IP) analysis that can be used to test & compare the cable (and

network) to satisfy required network standards.

In addition, NET200 provides a Tone-generating function used to identify and trace the cable in cavities (such as walls, floors, etc.). It also

provides a Continuity-test function to check out the continuity of the cable.

NET200 is a high-tech all-in-one instrument suitable for installing, repairing and maintaining business network services based on UTP/STP

cables, Coaxial cables, Telephone cables, and other metallic cable pairs cost effectively.

The tester comes with the accessories listed below. If an item is damaged or missing, contact your supplier immediately.

4. Connecting Cables

Before connecting cables, be sure to check the following:

1. Power sources (over 6.5 volts) should not be connected to the far end of the cable.

User’s manual for NET 200

2. Cable must be connected to only one of the two connectors: BNC connector (② in Figure

Depending on the cable you want to connect, you can use:

Coaxial Cable Connect it directly to the BNC connector.

Shielded Twisted Pair

) or RJ45 connector (③ in Figure 1).

The tester is not intended to be connected to active systems, or equipment. Prolonged exposure to the voltages applied by these interfaces

may damage the tester.

If the tester detects voltage over 6.5V, a “WARNING” screen is displayed. Disconnect the tester if the voltage warning symbol appears.
