Extech Instruments ExStik PH100 User Manual

5 PH100/PH110-en-US_V3.3 10/21
15-Storing Readings into Memory
1. Short 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. Short 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 short pressing
the MODE button.
1. Short 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, short
press the MODE button. The location number is displayed first, followed by the reading stored
in that location.
3. To exit the recall mode, short 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.
Making a Measurement
Place the calibrated pH meter into a sample of your solution.
The display will flash while the meter is making the measurement. When the display stops flashing
the measured pH value is displayed. It may take 10 to 15 seconds more to stabilize.
Note: If the display does not stop flashing, the meter or electrode is defective.
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 10 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. Factory calibration data for all models will be retained,
however.
