5. When “CAL COn” displays, press ENTER key to view the
default cell constant at 100%.
Press ENTER key again to show
the measured conductivity value.
Use ▲ and ▼ keys to scroll to
the standard’s Conductivity value
at 25
o
C.
6. Press ENTER key to calibrate
the Conductivity value shown.
Display will show the new cell
constant being displayed. This
value will be between 70% to
130%. Otherwise an error
message “CAL“ and “Err“
alternatively blinks to indicate
out of calibration range.
7. Press ENTER key to complete
the calibration, and you will
return to “CAL” and “COn”
menu.
8. Press MODE key and it brings
you to the Measure mode.
NOTE : Gently stir the electrode in
a container filled with calibrating
standard, and ENSURE that no
bubble is trapped during the
calibration process to avoid
erroneous reading.
IMPORTANT : The correct
Temperature Coefficient should be
selected prior to Conductivity
calibration. (Refer to Section 5.5 for
Setting Temperature Coefficient).
