ECO Inverter Analyzer (Model : IA-S)  is suitable to check all inverter products. It can be used to analyze the fault in Air Conditioners (AC’s), Refrigerators etc. It helps to diagnose whether there is a Compressor failure or a PCB failure.


  • Helps to Diagnose Fault in Inverter Based Products
  • 60 – 600V AC, 40 – 400Hz (Max. for 5 minutes)
  • No Battery Required
  • Rugged, Handy, Easy and Safe to Use
  • Color Identified Test Probes with Insulated Crocodile Clips for R, Y, B Connections
  • LED Based Instant Diagnosis


In case of a breakdown,

  • Step 1: Turn the power off.
  • Step 2: Remove the connections between the Compressor and PCB.
  • Step 3: Check and ensure that the charged voltage of built-in smoothening electrolytic capacitor drops to < 10V DC or below while carrying out any service.
  • Step 4: Connect Inverter Analyzer instead of Compressor by connecting the faston terminals of the PCB to the Crocodile Clips of the Inverter Analyzer (R, Y, B respectively). Be careful not to touch the Crocodile Clips (R, Y, B) with each other.
  • Step 5: Turn the power on and operate the A.C. or Refrigerator.
  • Step 6 (Diagnosis): When all LED’s of the Inverter Analyzer are lit uniformly, it means the PCB is proper and Compressor is faulty. When any / all LED’s are not uniformly lit, it means there is fault in the PCB.
  • Step 7: On completion of diagnosis, be sure to switch off the power. Then remove the connections of the Crocodile Clips of the Inverter Analyzer. Re-connect the fasten terminals of the PCB to Compressor firmly. Loose connections may lead to burning of the terminals.
