5.2 Taking Conductivity or TDS Measurement
5.2.1 Automatic Temperature Compensation
For automatic temperature compensation (ATC) simply
plug the conductivity probe into the meter (see page 6 for
directions). The ATC indicator will light on the LCD.
NOTE: If the ATC indicator does not light, manual
temperature compensation may be selected in
the meter’s SETUP mode. See Program P7.3 in
Section 7.8 for directions on selecting Automatic
