Log time is the longest time in seconds the pH controller will wait for the pH readings to settle. The
controller usually cycles before this maximum time is reached. The minimum setting for the log
time is 20 seconds. Press the up or down arrows adjust the sample time. (Tip: use 20 seconds
unless there is a special reason to allow a longer wait time)
Select the type of water you are using to clean the electrodes between samples. The available
types are TAP, RO (reverse osmosis), or DI (de-ionized). T
ip: If you don’t want a baseline wash
performed every 40 cycles, use RO setting rather than Tap or DI (regardless of actual water being
used).
Turning on the extra wash option will add 1.5 seconds of cleaning per cycle. The extra wash is
performed by automatically stopping the shoe briefly during the cycle. Use this feature if you have
noticed the electrodes are not cleaning during the cycle. Put a checkmark in the box to turn the
extra wash on and uncheck to turn off the extra wash. Tip: water usage will double if extra wash is
used.

The display is showing the pH values from the pH electrodes, conductivity of the top 1’ (30 cm) and
top 3’ (90 cm) of the soil, and whether you have GPS or DGPS (differentially corrected) signal.
