Conductivity Setup:
Stable Indicator/Auto Read Mode/Cell Constant
XL20, 30, 50 and 60 meters
Select Stable Indicator
This setup option lets you turn ON or OFF the stability indicator. When this function is turned on,
the STABLE indicator appears when the conductivity reading is stable.
To select Stable indicator
1. Touch ON or OFF to turn stable indicator on or off.
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 any resistivity fluctuations.
To select Auto Read Mode
1. Touch MANUAL or AUTO to choose the desired read mode.
Select Cell Constant
This setup option allows you to select the appropriate cell constant of the conductivity cell that
you are using. There are three cell constants to choose from. Each is used for a different range of
conductivity. The following indicates the optimal conductivity range for the accumet conductivity
cells.
Optimal Conductivity Range
Cell Constant 2-cell 4-cell
0.1 0.5 to 200 µS/cm Not Available
1.0 0.01 to 2 mS/cm 0.01 to 20 mS/cm
10.0 1 to 200 mS/cm 1 to 200 mS/cm
Check the part number on your accumet
®
conductivity cell and compare to chart on the previous
page to determine the cell constant of your conductivity cell.
To select Cell Constant
1. Touch 0.100/cm , 1.000/cm , or 10.00/cm to choose the correct cell constant.
When you change cell constants your calibration factor will automatically reset to default
values. It is recommended that you standardize your meter to establish a new calibration
factor.
Regardless of the status of the Auto Read Mode,
STABLE will be displayed as the meter recognizes
the measurement as stable.
