Zero calibration
Dip the sensor into the buffer solution pH=7 to perform the first point calibration (zero calibration).
[Z.CAL]
push the key for 3 seconds.
It appears the D1.1 display and message
Zero cal
alternate to the pH value.
Allow the pH value stabilization.
[SHIFT]
push the key to read the memorized buffer solution value.
[ENTER]
push the key for 3 seconds to confirm the buffer solution value.
If the new value is out of the accepted limits the display will show the error message
Zero err
[ENTER]
push the key for 3 seconds to delete the message and to turn to main display
If the new value is accepted, the display will show the message
Last cal
for few seconds and then it
proposes to register the date by the flashing cursor under last digit.
XX / XX / XX
[INCR]
push the key to modify the last digit if necessary
[SHIFT]
push the key to position the cursor on the other digit to be modified with same procedure.
[ENTER]
push the key for 3 seconds to confirm the date value.
This date value will be shown when switching ON the meter and when ending the next zero or
sensitivity calibration so to be modified with the new date.
If the memorized buffer solution value doesn’t correspond to the buffer solution used for th
e
calibration, proceed as follow:
[SHIFT]
push the key to read the memorized buffer solution value with the flashing cursor under the
last digit
XX.XX pH
[INCR]
push the key to modify the last digit if necessary
[SHIFT]
push the key to position the cursor on the other digit to be modified with same procedure.
[ENTER]
push the key for 3 seconds to confirm the adjusted value.
At this point the procedure is same as the above procedure with the recognized buffer solutions.
Sensitivity calibration
Dip the sensor into the buffer solution pH=4 or pH=9
[S.CAL]
push the key for 3 seconds.
It appears the D1.2 display and message
Sens Cal
alternate to the pH value.
Allow the pH value stabilization.
[SHIFT]
push the key to read the memorized buffer solution value.
[ENTER]
push the key for 3 seconds to confirm the buffer solution value.
If the new value is out of the accepted limits the display will show the error message
Sens err
If the new value is accepted, the display will show the message
Last cal
for few seconds and then it
proposes to register the date by the flashing cursor under last digit.
XX / XX / XX
[INCR]
push the key to modify the last digit if necessary
[SHIFT]
push the key to position the cursor on the other digit to be modified with same procedure.
[ENTER]
push the key for 3 seconds to confirm the date value.
This date value will be shown when switching ON the meter and when ending the next zero or
sensitivity calibration so to be modified with the new date.
The message
Update
indicates the new calibration values have been memorized.
