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.

DSP TDR Quick Start Guide
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

Charging – Displayed when the battery is charging. When charging, the battery
voltage will be shown between 12 and 14 VDC (dependent on charging source).
100% Charge – Displayed when the battery is charged from a minimum of 7.50 VDC or
approximately 100% of battery capacity.
75% Charge – Displayed when the battery is charged from a minimum of 7.25 VDC or
approximately 75% of battery capacity.
50% Charge – Displayed when the battery is charged from a minimum of 7.00 VDC or
approximately 50% of battery capacity.
25% Charge – Displayed when the battery is charged from a minimum of 6.50 VDC or
approximately 25% of battery capacity. When the battery charge drops to this level, it
is recommended that the battery is charged soon.
0% Charge – Displayed when the battery is charged to less than 6.50 VDC or
approximately 0% of battery capacity. When the battery charge drops to this level, it is
recommended that the battery is charged immediately.
On-Screen charging status
The Title Bar at the top of the screen displays the battery voltage and the following
charging status icons:
Battery status
Three Battery Status Indicators are located on the front panel. These indicators represent
the status of each of the three internal batteries and their charging status.
The indicators will illuminate when the charger is connected and the following conditions
are met:
• A solid Green indicator is displayed when the corresponding battery is fully charged.
• A solid Red indicator is displayed when the corresponding battery is charging.
• A flashing Red indicator is displayed when the corresponding battery or charging
circuit has a fault. In this case, the meter will need to be serviced by a Certified
Repair Center. Before sending in the unit for repair, contact VIAVI for an RMA.
• The indicators are not displayed when there is no power supplied to the charger.
