6.5. Readout of the last calibration date
The meter remembers the dates of calibration of all electrodes, cells and
sensors in every measuring function. Before starting work it is possible to
check the date of the last calibration.
In order to do so, in the measuring mode:
-
press the
button until the electrode number displays in the upper row
of the display ( , or symbol);
-
using the , buttons choose the electrode number that is to be
checked and press the
button shortly. The date of the last calibration
will be displayed in the following format: month – day and the year will be
displayed below (Pic. 7). On the left side of the display the electrode
number is shown.
Blinking date informs about expiration of the electrode’s calibration
validity. Introducing the calibration time is described in the point 6.6.
Pic. 7.
The meter memorises the date during calibration. If the date in the meter‘s
clock is changed after calibration, the date of calibration validity expiration will
be faulty signalised. It is important to set the current date before calibration.
Return to the readout of the electrode number mode by pressing the
button, and to the measuring mode by pressing the button.
