Description
The measuring instrument of subscriber lines the SHAFT - the options "reflectometer", "bridge" - is measuring system which consists of two cable devices: full-function reflectometer and measuring bridge.

Implementation of two methods of measurement in one device allows to define more precisely and more correctly distance to the place of damage.

Basic functions:

determination of nature of damage;

  • stay and exact range sensing to the place of damage or heterogeneity of the line
  • comparison of reflectograms of different lines (modes: line memory, memory memory);
  • mode two screens;
  • digital filtering of reflectograms;
  • measurement of coefficient of shortening of the line with its known length;
  • measurement of length of cables;
  • measurement of insulation resistance, loop, ohmic asymmetry, line capacitances.

Technical characteristics

  • measurement range (at To shortening 1,5)-0,025 … 64 km
  • resolving ability - 0,12 m
  • outgoing resistance - 50 … 250 Ohms
  • pulse width, nanosecond 20 … 25000
  • range of gain, dB 74
  • range of measurement of loop resistance from 0,1 Ohms to 10 kOhm; loop resistance measurement error: 0,1%+0,1 Ohm
  • range of measurement of an ohmic asymmetry from 0,1 to 100 Ohms; measurement error of an ohmic asymmetry: 0,1% +0,1 Ohms
  • range of measurement of line capacitance from 1 nf to 2 microfarad; capacity measurement error: 2%;
  • insulation resistance iziyereniye range from 1 kOhm to 50 GOM; insulation resistance measurement error: 2%
  • measurement of distance to the place of damage (isolation lowering); a range sensing error to an insulation failure mesi (for Rp of =0-3 megohms): 0,1%+1 m;
  • function of the voltmeter of a constant and alternating voltage (from 0 to 300 V)
  • function of the generator (to the line the sine signal with a frequency of 1000 Hz is given)
  • test voltage at measurement of insulation resistance: 180 і 400 Century.

The device allows to save the received parameters in memory of the device and to transfer them to the computer (interfeysusb);
In the device functions of measurement of level of a charge of accumulators and autopower off are implemented.
The modes of measurement and the received parameters are displayed in a graphic and alphanumeric view on the LCD indicator (320*240) with illumination.
Device weight with accumulators no more than 1.1 kg
Overall dimensions of 260*15*62 mm
By request the inductive probe is included in the package of delivery, it is intended for check of operability of a cable and identification of couples or lived in the contactless way.
