will escape and return to measurement mode.
Once the desired setup item has been se-

The conductivity of an aqueous solution is the measure of its ability to
carry an electrical current by means of ionic motion.
The conductivity invariably increases with increasing temperature.
It is affected by the type and number of ions in the solution and by the
viscosity of the solution itself. Both parameters are temperature de-
pendent. The dependency of conductivity on temperature is expressed
as a relative change per degree Celsius at a particular temperature,
commonly as percent per C.

calibration buffers.
