15-Storing Readings into Memory
1. Momentarily press the MODE button to store a
reading. The LCD will briefly display the
memory location number and then the value
stored (Data Hold will activate).
2. Momentarily press MODE again to return to
normal operation.
3. Repeat step 1 to store the next reading and so
on.
4. After 15 readings are stored the ExStik
TM
will return to memory location 1 and start
overwriting existing data with newly stored data.
Recalling Stored Readings
Note: Check that the HOLD symbol is not displayed. If it is, exit the HOLD function by
momentarily pressing the MODE button.
1. Momentarily press the CAL button and then press the MODE button immediately
after
CAL is displayed; the storage location number (1 through 15) will flash. If the CAL
mode is accidentally accessed (display flashing), press the CAL button again to exit.
2. The last reading stored will be displayed first. To advance through the stored
readings, momentarily press the MODE button. The location number is displayed first,
followed by the reading stored in that location.
3. To exit the recall mode, momentarily press the CAL button and the ExStik
TM
will return
to normal operation.
CAL Reminder Display
When the ExStik
TM
is turned on in the pH mode for the 15th time without recalibration, the
‘CAL’ icon appears on the LCD indicating that the ExStik
TM
may require calibration. Some
applications may require recalibration of the electrode more frequently than others. The
CAL display is simply a reminder and will turn off when the pH electrode is recalibrated.
RENEW Display
A flashing ‘RENEW’ warning indicates that the probe may be nearing the end of its useful
life. If cleaning or recalibration does not cause the RENEW icon to disappear, replace the
electrode. The RENEW display appears when the output of the pH electrode fails a
diagnostic test.
Considerations
• If the unit appears to be locked (display frozen) it is possible that the Data Hold mode
has been inadvertently accessed by pressing the MODE button. Simply press the
MODE button again or turn the meter off and restart if the display appears frozen.
• If the meter does latch up and no button presses revive it, remove the batteries, push
the ON button for 3 seconds and then reinsert the batteries.
• Note that if the batteries are removed, any stored readings will be discarded. Also, the
user calibration data for pH will be cleared. New user pH calibration data is required.
Factory calibration data for all models will be retained, however.
