When the value stabilises, press the
button. The result will blink, what
informs that the calibration value has been recorded in the meter‘s memory;
simultaneously, the corrected readout equal to the buffer‘s value will be
displayed in the upper row (Pic. 13.). If the reading is still different than the
buffers value, wait until it stabilises and press the
button again.
Pic. 13.
The meter will record the correction. If the meter cannot recognise the buffer,
the
symbol will be displayed. In this case it is necessary to check the
value of the buffer solution or the electrode which may be broken.
The meter calculates only the pH buffers values detected during calibration.
The values entered earlier into the memory do not affect the results.
After finishing calibration in the first buffer rinse the electrode and the
temperature probe with distilled water and start calibration process in the
next buffers, acting according to the procedures given in point i and when the
calibration process is finished, escape the calibration mode by pressing the
button.
When one electrode is calibrated, it is possible to calibrate two another
electrodes, choosing the remaining electrode numbers.
After choosing the electrode number, entering the calibration mode and
escaping it without making calibration, the stored characteristic will be
erased and the standard characteristic will be adopted.
