Notes
Cell constants will degrade with time and
usage. You can use this feature to alert you
to when your probe needs cleaning or to
when you need to replace your probe.
P6.0: Viewing conductivity/TDS probe data
Program 3 has five "view only" options that let you check your conductivity/TDS
probe’s parameters for diagnostic purposes. These options show you the effective cell
constant for each range. The cell constant is adjusted according to your calibration.

P5.0: Viewing previous conductivity/TDS calibration data
This mode lets you recall previous conductivity or TDS calibration data, which lets
you know at which points this meter was previously calibrated. This is a “view only”
mode.
TDS values are proportional to conductivity values. Note that if you calibrate a TDS
value in an equivalent conductivity range, the TDS value will replace the previous
conductivity value, and vice versa.
