∆ / RESLN
Primary Function
Select next higher pH buffer values in the pH calibration mode. Also used to scroll
through SETUP mode options.
Secondary Function
Toggle the pH resolution between 0.01 pH and 0.1 pH.

5 /
∇ / SLOPE
Primary Function
Select the next lower pH buffer value option in pH calibration mode. Also used to
scroll through some SETUP mode options.
Secondary Function
Display the percentage slope of the pH electrode when in the pH mode. While in Ion
mode, it displays slope of ion electrode in mV/decade.

6 / SET TEMP / OFFSET
Primary Function
Press to calibrate ATC temperature probe or to set manual temperature.
Secondary Function
Displays the offset of pH electrode. This is useful as a diagnostic function to
determine the quality of the probe that is connected to the meter.
