LABEC M-TIT-5 - Manual (Page 17)

The meter shows menu on the top of screen which including ‘View’ (if there is titration data or
stored data), ‘Titrate’, ‘Mode’, ‘Set’, ‘Calibrate’ etc In the middle shows measuring result such as
current potential value (or PH value) and temperature value. On the right side is the press button
in common use including ‘Titrate’, ‘Clean’, ‘Feed’ and at the bottom, it displays the status of
titration panel, stirrer chart, electrode slope chart and system time. User can enter the
corresponding function panel by pressing menu, press button or the chart.
In case the connection of titration panel or measuring panel fails, user can press ‘Enter’ button
continue the operation, the current potential area displays as ’88.888’ and the status of titration
panel displays ‘Off Line’.
The meter has following functions: Feeding solution, Cleaning, Titration (including pre-titration,
preset end point titration, mode titration, blank titration and manual titration). It can calibrate
electrode slope, select burette, set burette coefficient, set stirrer speed, set system time, select
printer etc It displays titration curve dynamically in the process of titration. When titration
finished, user can view and stored titration data. And the meter can also generate user’s own
mode according to user’s requirement. The meter provides two sets of system mode and allow
user to view mode, delete mode, edit mode, hereafter we will introduce all these functions.
5. Feeding Solution
In the starting status, press ‘Feed’ bottom, titration panel starts to feed solution. The meter
displays as follows:

When feeding finished, meter will be back to starting status automatically. In the process of
feeding, if user can terminate feeding by pressing ‘End’ button, titration panel stop feeding and
meter remind user to Enter, shown as follows:
