3M 965DPS instruction manual Test Error R1+R2100*Rloop

K-Test Error: R1+R2<100*Rloop

The 965DSP checks to see that the sum of the faults is more than 100 times the loop resistance. The 965DSP will display the following screen if the sum of the faults is less than 100 times the loop resistance.

Press [Tab] to continue even though the fault values are too low. This may result in reduced accuracy of the measurement.

Press [Enter] to repeat the K-Test, starting with the “Open Far-End” screen. You should first find a new pair in the faulted cable with higher value fault resistances.
