SELECT MEASURE Changes the measured parameter to conductivity (default), TDS (total dissolved
solids), salinity or % concentration. When the parameter is changed, all other
configured settings are reset to the default values.
sc100 —When Concentration is selected, the CONFIG CONC option is added to the

DISPLAY FORMAT
10

. When set
to auto, the units change automatically with changes in the measured value. For
concentration measurements, changes the units for calibration and user conductivity-
concentration table—µS/cm, mS/cm (default) or S/cm.
TEMP UNITS Sets the temperature units to °C (default) or °F
T-COMPENSATION Adds a temperature-dependent correction to the measured value—linear (default:
2.0%/°C, 25 °C), natural water, temp table (enter x,y points in ascending order) or
none. For special applications, a user-defined linear compensation can be entered
(0–4%/°C, 0–200 °C). Natural water is not available for TDS or concentration.
