● The RCB-3-1T is used to verify and proof any High Voltage     Insulation Testers. It can be utilized to calibrate all High Voltage     Insulation Testers very accurately Analogs or Digitals. ● Some institutions and large industries requested their own calibrator     too, therefore, SEW started manufacturing the RCB for special     customers.
