Sampling time is the duration that the sampler assembly is in the soil. Typically 2 seconds is
adequate. In soil conditions that do not produce a firm core, this time may need to be set at 3
seconds in order to allow soil to begin flowing through cutting shoe. If soil conditions result in a
very firm core, the sampling time may be reduced to 1 second. In rocky conditions, use 1 second
sample time to reduce likelihood of sampler shoe damage. Press 1 or 2 to adjust the sample time,
press 3 to continue to the next screen.

Maximum 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 maximum log time is 20 seconds. (Tip: use 20 seconds unless there is a special reason to
allow a longer wait time) Press 1 or 2 to adjust the sample time, press 3 to continue to the next
screen.

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). Press 1 or 2 to cycle through the water
types, press 3 to continue to the next screen.
Tip: 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 stopping the shoe briefly during the cycle. Use this feature if you have noticed the
electrodes are not cleaning during the cycle. Press 1 or 2 to choose ON or OFF, press 3 to
continue. Tip: water usage will double if extra wash is used.
