TEST PROCEDURE
VERIFY CALIBRATION
After calibration, dip the meter in 12.88 mS/cm
calibration solution. If the value is accurate, it is not
necessary to conduct a 2nd point calibration. If it is
inaccurate, follow steps 5 to 6 to complete the 2
nd
point
calibration using the 12.88 mS/cm buffer solution.

a stable reading is reached. When the
stable
icon appears on the LCD, press the key to
complete one-point calibration. The meter returns to
measurement mode and the icon will appear at
