Analog Line Test Series
Model Number: ALT1500
  Focus
  The Analog Line Tester Series of Hand-held Transmission Testers combine the functions of a transmission line measurement (TIMS) instrument, a digital multimeter measurement (DMM) instrument and the function of a telephone handset with dial/talk/listen capabilities into one compact unit for simple operation and ensures the most cost effective solutions on the market. This feature selection guide is intended to give a clear & rapid indication of the functions available through the Analog Line Tester Series.
