Have you ever scrapped a board (loaded or bare) because of an internal power to ground short?

The Polar model 850A works to help you repair many of those boards you may have considered a write off.
It is a special instrument to find Power to Ground Short Circuits, it is a Shorts Locator.
It makes a different pitch sound depending on the resistance, and it can see milliohms.
That means you can move the probes along a track and hear if you are getting closer or further away from the short.
The accuracy of fault localisation is 1 - 2 mm.

Specifications:

• Detection of:
  • Shorts below 200 mOhm
    
  • Multilayer shorts excessive Vcc loads (static/dynamic)
    
  • Bus faults
    
  • Open decoupling capacitors
• Resistance ranges: Ohm, 200 mOhm, 2 Ohm, 200 Ohm, 20 kOhm
  
• Voltage ranges: 2 mV, 20 mV, 2 V, 20 V
