The 620 is no longer manufactured. It has been replaced with the excellent MicroScanner2.

Cable Length Measurements
 

  • Range : 1.0 to 350 m (2 ft to 999 ft)
  • 精度:5 % +0.5 m (7 % + 2 ft)

 
分辨率:

  • Measurement Units in Feet: 1 ft
  • Measurement Units in Meters
  • Cables < 100 meters: 0.5 米
  • Cables > 100 meters: 1 m

 
 
Failures Detected
 
Shorts:

  • Range of short detection: 0 m to 350 m (1 ft to 999 ft) 
  • Accuracy of distance to a short (Assumes short is 0 Ω): UTP/FTP/STP: 7 % + 3 m (7 % + 10 ft) & Coaxial Cables 10 % + 10 m (10 % + 30 ft) 
  • Resolution of distance to a short: UTP/FTP/STP: 0.5 m (1 ft) & Coaxial Cables: 1 米(5 英尺) 


开路

  • Range of open detection: 0 m to 350 m ( 0 ft to 99 ft) 
  • Accuracy of distance to an open: UTP/FTP/FTP: 10 % + 1 m (10 % + 3 ft) 
  • Resolution of distance to an open: Cables < 100 meters: 0.5 m (1 ft) & Cables > 100 meters: 1 米(3 英尺) 

 
Split Pairs:

  • Range of detection: 2 m to 350 m (6 ft to 999 ft). Split pair part of the cable must be at least 2 meters (6 ft) in length and greater than 10 % of the total cable length.
