Precautions

WARNING:

The maximum “RF” input voltage to the meter is 125 Volts

(AC or DC). A larger voltage will damage the meter.

WARNING:

Pursuant to FCC 15.21 of the FCC rules, changes not

expressly approved by VIAVI might cause harmful

interference and void the FCC authorization to operate this

product.

WARNING:

The antenna used for this instrument is installed at the

VIAVI factory or by VIAVI-approved repair facilities. During

operation of the device, a distance of 20 cm or more should

be maintained between the antenna in this device and person.

To ensure compliance, do not operate at closer distances

than this. The antenna on the unit is located inside the device

at the top of the unit attached to the back plastic case. Do not

use any antenna other than the installed antenna.

CAUTION:

Do not use the instrument in any manner not recommended

by the manufacturer.

CAUTION:

A strong electromagnetic eld may affect the measurement

accuracy of the meter.

22134505, Rev. 000 July 2019viii

Precautions (continued)

CAUTION:

Use only the battery charger supplied with the meter. Use of

any other charger may damage the battery.

NOTE:

Damage caused by improper cleaning of the display screen

will void the warranty of the unit.

NOTE:

Never use abrasive pads, paper towels, tissue paper, or

clothing to wipe the screen. If you do, these non-ultrasoft

materials can cause permanent damage by scratching the

screen or stripping the anti-glare coating off the screen.

NOTE:

Never use any type of window cleaner, soap, scouring powder,

or any cleanser with solvents such as alcohol, benzene,

ammonia, or paint thinner. These chemicals can react with

the materials used to construct the display which can lead to

hazing, yellowing, brittleness, or other types of damage.

ALERT:

Never spray liquid directly on the display screen as it could

run inside the unit and cause damage.

About the DSP TDR

In the event of a cable break or fault, the DSP TDR enables cable service provider maintenance

teams and contractors to quickly find the location to get service back online as soon as

possible. Since a cable break likely means an outage, pin-pointing it quickly is very important.

Length measurement accuracy is also critically important, as often the cable is underground

and must be dug out to make the splice. A lack of precision in this measurement means a

bigger hole must be dug. A TDR is needed to find breaks and faults, to keep the operator from

paying for unnecessary span replacements.

The DSP TDR is designed for field use and has step technology, which enables it to show

smaller faults, has no blind spot, and maintains accuracy for detecting impedance over the

entire length of the cable. Automatic impedance matching allows for faster trace results

without pulse width adjustments. In addition to the ability to find faults closer to the TDR (no

blind spot) the TDR has a resolution of less than 1 foot (0.3m). The higher energy step TDR has

an improved signal-to-noise ratio and digital averaging, eliminating noise interference, and

producing a much more detailed cable image than available with a pulse TDR.

Benefits

• Reduce outage and line problem troubleshooting time

• Features fast, complete, and precise measurements without blind spots

• Data upload and retention with StrataSync

• Built to last design for use in the real environment of Network Technicians

• Long battery life
