mode.

3.13 Change the user-selected conductivity/TDS ratio

Select the User mode to change a custom conductivity/TDS conversion ratio in the
range of 0.20 to 7.99.
To determine the conversion ratio for a custom solution of a known TDS ppm value,
measure the solution conductivity at 25 ºC with the MP Series meter and divide the
