DO7 Plus Micro Ohmmeter

Micro Ohmmeter – DO7 plus – Overview The DO7Plus is a 10A micro ohmmeter, suitable for applications within aerospace, utilities, cable or machine manufacturers or where a cooling curve is required to plot peak resistance. Sealed in an IP67 case, it is ruggedly constructed to ensure durability. This micro ohmmeter has a display length of 60,000 counts and auto averaging of forward and reverse measurement removes thermal emf differences. The DO7Plus micro ohmmeter has built in rechargeable batteries which will provide up to 1 hour of continuous use at 10A, and up to 20 hours at all other ranges. The data log memory using FRAM technology offers unlimited read/write cycles and over 10 years of data retention, without relying on internal batteries.
