• If the concentration is out of limits an exceeded range limit message will be displayed
blinking and the message
“Out of range”
will be shown. Another titration can be initiated
by pressing
Restart
. Prepare a fresh sample and then press
Restart.
Note:
If the end-point is not reached or it is not recognized or the input reading is out of range,
an error message will be displayed. The titration can be restarted after a new sample is
prepared by pressing
Restart
.
TIPS FOR AN ACCURATE MEASUREMENT
• Calibrate the instrument in 8.20 pH buffer solution at least once a day, before you start to
perform measurements.
• Purge the peristaltic pump to have the fresh titrant when starting a new calibration.
• Calibrate the peristaltic pump daily before performing a set of analyses.
• Clean the electrode in order to remove the possible coating from bulb.
• Precision of the measurement can be improved by using volumetric pipets for standard and
sample additions.
