3.4 Display mode

3.4.1 Reading stable display mode
When the measuring value is stable, smiley icon appears on LCD screen, see Diagram – 3. If the
smiley icon does not appear or flash, please do not record readings or calibrate until the measuring
value is stable.

3.4.2 Auto. lock on display mode
In parameter setting 3.1, set “Reading with HOLD” to “ON”, when icon is stable for more than 6
seconds, the meter will lock the value automatically and display HOLD icon, see Diagram – 4(b). In HOLD

mode, press key to cancel auto lock.

3.5 Data storage, recall and delete

3.5.1 Storage
Press key to store, icon displays on the top right corner of LCD screen which means it’s
the 12th group data, see Diagram – 5(a); Each meter can store 100 groups data. For single parameter
display mode, 1 serial number corresponds to 1 group measuring vale. For dual parameter display mode
(means pH+Cond. meter display mode), 1 serial number corresponds to 2 groups measuring value (pH
+ conductivity). So for this type of meter, actual store data is 100 groups, but storage number will be less
than 100. If press key again when storage value is full, icon will flash, see Diagram –5(c)
to indicate store memory is already full and need to be deleted for new store value.

3.5.2 Recall
Press key, meter will display stored 12 groups measuring value, see Diagram – 5(b), press
or key to turn page. Every page displays up to 8 groups data.

3.5.3 Delete
Data need to be deleted when storage memory is full, otherwise no more data can be stored. In
parameter setting 3.3 select “Yes” and press key, see Diagram – 5(d) to delete all stored value.
