Ion Setup: Auto Read Mode / Ion Stability Criteria
PH6500, PC6500 and PCD6500 meters
Technology Made Easy ...
Select Auto Read Mode
You can use this meter when the Auto Read function is active or when it is inactive. When the
Auto Read function is active, the meter will lock onto a reading when the meter recognizes it as
stable. The meter will not deviate from this reading until Measure is touched. If the Auto Read
function is inactive, then the meter will continuously monitor the concentration of the ion of
interest. The Measure screen display will indicate any fluctuation in the ion concentration.
To select Auto Read Mode
1. Touch MANUAL or AUTO to choose the desired read mode.
Set Ion Stability Criteria
This setup screen allows you to determine how quickly the meter will respond to electrode drift.
There are three speed settings: fast, medium and slow
To set Ion Stability Criteria
1. Touch FAST, MEDIUM, SLOW to choose the desired stability criteria.
Regardless of the status of the Auto Read Mode, STABLE will be displayed as the meter
recognizes the measurement as stable.
Stability criteria are more stringent at the slower setting. Therefore, if the highest precision is
required, then a slow setting would be desired. The default setting is the FAST and this should
be adequate for the majority of applications without making any changes.
