The Auto-Ohm 100 100A is a third generation micro-ohmmeter made by Vanguard Instruments Company.
The Vanguard Auto-Ohm 100 100A Micro-Ohmmeter features microprocessor-controlled measuring of very low resistances ranging from 1 micro-ohm to 300 milli-ohms with high accuracy.
The Vanguard Auto-Ohm 100 100A Micro-Ohmmeter is field-portable, rugged, and easily operated by first-time users having a minimum of training.
Featuring an LCD alpha/numeric display of the resistance measured the Auto-Ohm 100 100A‘s one-knob control operation is logical and simple:
• Turning the knob scrolls through a menu of possible options (displays in sequence)
• Pressing the knob activates the selected function.
As its name implies, the Vanguard Auto-Ohm 100 100A Micro-Ohmmeter operation is automatic, requiring little more from the user than connecting it to an unknown resistance and selecting the desired functions and its options. The Auto-Ohm 100 100A Micro-Ohmmeter automatically stores the last 3 resistance measurements, which can be displayed after testing.
