LABEC M-TIT-5 - Manual (Page 27)

In Diag.34, on left side is current stored assemble mode figure and current mode symbol, on the
right is relative parameter corresponding to the mode under cursor. Including Name of Mode, mV
or pH Titration, Number of End Point, Mode Storing Time, Sample Volume, Titrant
Concentration, End Point Value corresponding to Each End Point, Time Delay and End Point
Switch (Detailed instruction and amendment of Mode Parameter are in chapter ‘View Mode’).
On the top of Diag.34 is pressing button area. User can select proper mode on his own need. Press
‘Titration’ button, meter display ‘Start Mode Titration?’, press ‘Enter’ button to start mode titration.
7.3.1 mV/pH Titration Parameter
When mode is generated, the parameter is confirmed too, use is not able to amend. Diag.34
is pH titration.
7.3.2 End Point Number Parameter
When mode is generated, the end point number is confirmed too, use is not able to amend.
Diag.34 is one end point
7.3.3 Stored Time Parameter
This parameter only indicate current mode generation or the time when store.
7.3.4 Mode Title Parameter
This parameter is set for users better memory and management mode. User can edit this
parameter.
7.3.5 End Point Parameter
This end point parameter is also the actual end point value for this time titration. User is
allowed to amend this parameter, but the amendment of end point value will change the final
titration result directly, user should pay attention to this before amendment.
7.3.6 Time Delay Parameter
This Parameter means the delay time after the titration reaches the end point. User is allowed to
amend this parameter. Also the amendment of delay time may change the final titration result.
User should pay attention to this before amendment.
7.3.7 End Point Switch Parameter
Normally, when mode is generated, end point switches are all set as ‘ON’ which means this
end point is valid. If in multi-end point titration, user finds a certain end point is unnecessary
or user need to screen a certain end point with some other reason, you can set the switch of
certain end point to ‘OFF’, then in the process of titration, meter will jump over this end point
but will not ignore all the other end point.
7.3.8 Sample Volume Parameter
When mode is generated, the parameter is usually set to BLANK and user should input this
parameter when calculating concentration value (see 8.1.3 ‘Sample Concentration).
