  1. Transmitter 20m R3 R4 40m Cable measuring example Integrus Tech Cable Measuring

  2. Step 1 Signal Delay Factor of Used Cable Use the Signal Delay Factor that is specified by the manufacturer of the cable. Integrus Tech Cable Measuring

  3. 20m 30m 30m 20m 40m 20m Step 2 Measure the Cable Lengths R3=20m R1=30m R2=30+20=50m R4=20+40=60m Integrus Tech Cable Measuring

  4. Step 3 Cable lengths * Cable Delay Factor R1=30 * 5.6 = 168ns R3=20 * 5.6 = 112ns (Example) Cable Signal Delay = 5.6 ns/m R2= 50 * 5.6 = 280ns R4=60 * 5.6 = 336ns R4=60 * 5.6 = 336ns Integrus Tech Cable Measuring

  5. 7 5 0 2 Step 4 Calculate Delay Switch Positions (336 – 168) / 33 = 5.39 (336 – 112) / 33 = 6.78 Switch Position = (Max. Signal Delay – Delay Rx) / 33 (336 – 280) / 33 = 1.69 (336 – 336) / 33 = 0 Integrus Tech Cable Measuring
