Remote Interface Operation
The automatic input resistance mode can be enabled / disabled. With
AUTO OFF (default), the input resistance is fixed at 10MΩ for all ranges.
With AUTO ON, the input resistance is set to >10GΩ for the three lowest
DC voltage ranges (100mV, 1V and 10V). Use the following command
from your PC terminal to disable the auto input DC resistance setting
(the result is a fixed input DC resistance at 10M Ω for all
measurements.)

4.1.5 Threshold Resistance (Continuity)

Definition
When testing continuity, the beeper goes off when the measured
resistance is less than the threshold resistance. The threshold resistance
can be set to any value between 1Ω and 1000Ω.
