New 3M dynatel 946-pt subscriber loop tester 946DSP
DYNATEL 946DSP PT SUBSCRIBER LOOP TESTER
INCLUDES 946 DSP PT, SHOULDER STRAP, INSTALLED BATTERIES,SOFT CARRY CASE, & QUICK START QUIDE
Full-Featured POTS/Inside Wiring Testing
The 3M Dynatel line tester 946-PT is a full-featured unit enabling installation and maintenance crews to efficiently qualify and troubleshoot inside wiring for telephone
service qualification. With the push of a single button, the easy-to-use 946-PT tester performs a wide range of tests to analyze twisted pair problems. Results can be stored and uploaded to a PC for efficient record keeping.
FLEXIBLE , PRACTICAL FEATURE S
The 946-PT line tester is designed for functionality and ease of use. Features include:
Graphical user interface user-friendly, icon-based display of test results
Single button autotest for line qualification with pass/fail indication
Backlit high resolution/high contrast LCD
Simultaneous display of T-R, T-G and R-G readings in Ohms, Volts and Opens.
Accepts Alkaline, Ni-Cad or NiMH batteries
RUGGED , WEATHER -RESISTANT DESIGN
The Dynatel brand and its distinctive Dynatel yellow color are your assurance of rugged dependability.
Voltage (V) Detects and measures the presence of foreign DC and AC voltages on R-T, R-G and T-G. Measures CPE voltage.
Current (mA) Measures DC line current from CPE.
Ground Resistance Measures and displays the ground path resistance (when supported by the switch).
Ringers Measures and displays the equivalent ringer count where one ringer equals 0.47uF.
Resistance test ( ) Measures conductor and insulation resistance up to 30 megohms. Accurate readings in the presence of foreign voltage. Full autoranging.
Insulation soak test Monitors the leakage resistance from the test leads to ground and indicates changes in the insulation resistance over time in the presence of high
voltage. Increasing resistance is an indication of a wet fault and decreasing resistance is an indication of oxidation, which is breaking down and
Opens Detects opens. Measures the open length of cable pair at distances up to 100,000 ft.
Tone Provides 577 Hz ID tone for conductor identification, and 404, 1004 and 2804 Hz precision tones for determining circuit loss.
Loss Measures voiceband loss up to 5KHz, displaying frequency and level.
Noise Measures circuit noise and power influence, and displays calculated balance. C-Message Weighting is used in the U.S. and Canada, and a
Psophometric Filter where ITU (CCITT) Standards are used.
Longitudinal balance This test provides active measurement of line balance.
Dial key Allows storage of 10-14 digit numbers for testing of active lines.
Result summary screen This screen shows the results from last V, mA, Ohms, Opens, Noise, PI, and LB test in a tabular form for easy analysis. If desired, these results can
then be saved to one of 10 result storage locations.
Result storage Storage will be provided for 10 sets of results. Each set will include a 10 digit numeric identifier and the following measurements: V (T-R), mA, Ohms
(T-R), Ohms (T-G), Ohms (R-G), Open Length (T-R), Open Length (T-G), Open Length (R-G), Noise, Power Influence, and Longitudinal Balance.
Result review Means will be provided to review any result set on the screen of the 946-PT.
Result upload Results can be uploaded to a PC through the test leads using an adapter and pc software provided with the unit.
