• Accuracy +/- 10mv
• Displays measured voltages
• Indicates a failure if out of range
• LED monitor of +5V, +12V and –12V supplies

Intrusive Voltage Test
•Detects voltages which may cause       damage to boards
• Measures and displays intrusive voltages
• Alerts user to fix intrusive voltage
• Measurement of +40Vdc to –40Vdc voltages
• Accuracy +/- 40mv

Short Test
• Checks for shorts between signals
