The DSP fails self calibration

When you perform a self calibration on a DSP-4X00 there are a couple of things to consider :

  1. If the battery is new you need to fully charge the battery before attempting to operate the unit. It normally takes approximately 4 hours to fully charge the batteries. You can determine that the battery is fully charged when the status light is a steady green.
  2. Allow a 1 minute warm-up time before performing a self calibration. Always perform the self-calibration only after the test tool has warmed up to an ambient temperature between 10ºC and 40ºC.
If the above conditions have been met and the unit fails the self calibration with the above error message, then there is a hardware issue. We regret to say we are no longer able to offer calibration and repair for the DSP-4x00 CableAnalyzer. It has been replaced with the DTX CableAnalyzer.
