Polar Toneohm 950, an advanced shorts locator for circuit boards.
Purpose:
• Identify shorts in PCB traces, especially useful when troubleshooting multilayer PCBs.
• Traces voltages, resistances and currents along traces to find exactly where the fault is.
Features:
• Multiple resistance ranges (from milliohms to kiloohms).
• Current and voltage control for tracking.
• Possibility to connect different types of probes and use headphones for acoustic feedback (hence the name “Tone-Ohm”).
A very useful device in the repair and production of electronics.
