The Vanguard Auto-Ohm 100 Ampere Micro-Ohmmeter can be used to measure resistances, bushing contact joints, or for any low-resistance measuring application.
The Auto-Ohm 100 can accurately measure resistances ranging from 1 micro-ohm to 300 milliohms, and can output a test current from 10 Amperes to 100 Amperes.
The Auto-Ohm 100 applies a true DC current from 10A to 100A to the resistance load to be tested.
Vanguard Auto-Ohm 100 Features:
• 100A DLRO
• Accurately measures resistance ranging from 1 µΩ to 300 mΩ
• Outputs test currents from 10A to 100A
• Available automatic test mode
• Three most recent resistance measurements are stored internally
• Simple push button control from the front panel
• Controlled rise/fall test current
