LIMITED WARRANTY & LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship
under normal use and service. The warranty period is one year and begins on the date
of shipment. Parts, product repairs and services are warranted for 90 days. This war-
ranty extends only to the original buyer or end-user customer of a Fluke authorized re-
seller, and does not apply to fuses, disposable batteries or to any product which, in
Fluke’s opinion, has been misused, altered, neglected or damaged by accident or ab-
normal conditions of operation or handling. Fluke warrants that software will operate
substantially in accordance with its functional specifications for 90 days and that it has
been properly recorded on non-defective media. Fluke does not warrant that software
will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-
user customers only but have no authority to extend a greater or different warranty on
behalf of Fluke. Warranty support is available if product is purchased through a Fluke
authorized sales outlet or Buyer has paid the applicable international price. Fluke re-
serves the right to invoice Buyer for importation costs of repair/replacement parts when
product purchased in one country is submitted for repair in another country.
Fluke’s warranty obligation is limited, at Fluke’s option, to refund of the purchase price,
free of charge repair, or replacement of a defective product which is returned to a Fluke
authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center or send
the product, with a description of the difficulty, postage and insurance prepaid (FOB Des-
tination), to the nearest Fluke authorized service center. Fluke assumes no risk for dam-
age in transit. Following warranty repair, the product will be returned to Buyer, transpor-
tation prepaid (FOB Destination). If Fluke determines that the failure was caused by
misuse, alteration, accident or abnormal condition of operation or handling, Fluke will
provide an estimate of repair costs and obtain authorization before commencing the
work. Following repair, the product will be returned to the Buyer transportation prepaid
and the Buyer will be billed for the repair and return transportation charges (FOB Ship-
ping Point).
THIS WARRANTY IS BUYER’S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF
ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED

LOSS OF DATA, WHETHER ARISING FROM BREACH OF WARRANTY OR BASED
ON CONTRACT, TORT, RELIANCE OR ANY OTHER THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty,
or exclusion or limitation of incidental or consequential damages, the limitations and ex-
clusions of this warranty may not apply to every buyer. If any provision of this Warranty
is held invalid or unenforceable by a court of competent jurisdiction, such holding will not
affect the validity or enforceability of any other provision.

codes (QuickBERT-T1 only)
•Transmits HDSL loop codes (QuickBERT-T1 only)
•Has the ability to insert logic, BPV, and frame bit errors (QuickBERT-T1
only)
•Performs BERT and Fractional T1 BERT (Nx56 and Nx64)
•Captures and displays DTMF digits
•Measures DS1 frequency, level, and clock slips
•Displays standard T1 alarms
•Displays major T1 performance parameters
•Displays AMI or B8ZS line coding
•Measures DS0 level and frequency
•Monitors voice using internal speaker (or headset)
•Displays DS0 data and signaling bits
•Automatically synchronizes to and displays the T1 framing type, line
coding, and BERT pattern

1-3. Safety Information
WWarnings and Precautions
To avoid possible electric shock or personal injury, and to
avoid possible damage to the Test Set or to the equipment
under test, follow these guidelines:
•Before using the Test Set inspect the case. Do not use the Test Set if it is
damaged.
•Inspect the test cables for damaged insulation or exposed metal. Check the
cables for continuity. Replace damaged test cables, before using the Test
Set.
•Do not operate the Test Set around explosive gas, vapor, or dust.
•Do not operate the Test Set with the case (or part of the case) removed.
•Recharge the battery as soon as the low battery indicator appears. With a
low battery, the Test Set might produce false readings.
•When servicing the Test Set, use only specified replacement parts.
1-4. Software Revision
To view the software revision number and the date of release, press and hold
the RESTART key while powering up the unit.
1-5. Self Test
After the startup screen, a self test will activate and the version build date will
be displayed. To perform an LED test, press and hold the RX INPUT key
while powering up the unit.

1-7. Toolpak Accessory Kit
The QuickBERT-T1 and QuickCHECK-T1 come with a ToolPak accessories
kit. This kit includes a universal hanger, hook-and-loop straps, and a magnet.
The universal hanger attaches to the unit and can be used by itself on a nail or
hook, with a piece of rope or stiff wire. Two hook-and-loop straps are used
with the universal hanger and can be wrapped around a pipe or beam. The
ToolPak’s magnet is used with the universal hanger and is strong enough to
securely hold the test set.
Hanger inserts
into slot with tab
extension facing
out, for proper use.

1-8. View Angle Adjustment
The VIEW ANGLE control, located on the top panel of the test set, is a
recessed control used to vary the display’s view angle.
Note
In order to prevent damage to the test set, use only an isulated, flat-
bladed tool to adjust the display’s view angle.
1-9. Accessories
Additional cables and headsets for use with the QuickBERT-T1 and
QuickCHECK-T1 are available from Fluke Corporation. For information,
please contact customer service at 888-993-5853.
1-10. Cleaning
When cleaning the display surface, use a soft cloth (such as a gauze) with mild
soap and water.
1-11. Environmental
Do not exceed the operating temperature limits of 32° to 122° F. Protect your
unit from exposure to direct sunshine or high temperature/humidity for
prolonged periods of time. These conditions may cause degradation to the
display.
1-12. Manual
This manual is arranged so you can quickly and easily find the information you
need. The following is an overview of the contents of this manual.
•Chapter 1, Introduction, familiarizes you with QuickBERT-T1 and
QuickCHECK-T1 highlights.

Chapter 2
Overview
2-1. Introduction
This chapter of the manual contains information to familiarize you with
QuickBERT-T1 and QuickCHECK-T1 controls and indicators. Refer to
Appendix A for test set specifications. Figure 2-1 and 2-2 illustrate all control
and indicator locations.
2-2. Power
The primary power source for the QuickBERT-T1 and QuickCHECK-T1 is a
rechargeable, NiMH (nickel metal hydride) battery pack. An auxiliary power
connector is available for use with an A/C power adapter (which is provided
with the unit). The ON/OFF switch is located between the power (9 VDC)
jack and the RX bantam jack on the top panel of the unit. During battery
operation, the LOW BATTERY LED will illuminate to indicate that the
battery pack has nearly exhausted its charge and that the test set should be
recharged.
Note
If the test set is not turned off before the battery is completely
exhausted, the unit will shut down to prevent battery damage. If this
occurs, the unit will resume normal operation once recharge is
performed.
2-3. Primary And Reference T1 Receivers
The QuickBERT-T1 and QuickCHECK-T1 are equipped with two T1
receivers: primary (Rx) and reference (REF). The test set performs analysis on
the signal present at the Rx receiver. The REF receiver provides the clock
reference for performing clock-slip measurements.
On the QuickBERT-T1, the REF receiver functions as the transmit clock
source when external (EXT) clock is selected. For additional information on
clock-source selection, see section 2-18.

633/635
Users Manual

The RX INPUT key is provided for the Rx T1 receiver. Before making a
connection from a T1 line to the RX jack, the RX INPUT key should be set
appropriately. For additional information on the RX INPUT key and its
settings, see section 2-42.
A bantam jack is provided for the REF T1 receiver. This jack is automatically
terminated by the test set.
2-4. Controls
The QuickBERT-T1 is equipped with 19 pushbutton keys and one switch. The
TX PATTERN, TX LINE CODE, and TX FRAMING keys are yellow. The
RESTART key is red. All remaining pushbutton keys are black.
The QuickCHECK-T1 is equipped with 9 pushbutton keys and one switch. The
RESTART key is red. All remaining pushbutton keys are black.
The following is a list of the controls which are defined in sections 2-5 through
2-58. An asterisk is placed next to those controls that are only applicable to the
QuickBERT-T1. The remaining controls are included on both units.
