Press the down arrow in the Conductivity Calibration Set Up sub menu to highlight
the Cal 1 (2 or 3) Buffer(mS) option. Press the Enter key to move the highlight to the
current value. Use the Escape [ESC] key to move to other menu levels or continue
with the Conductivity calibration settings as follows. A data entry box will appear in
the centre of the screen. This has 7 digits and represents the calibration standard in
value in mS, with three decimal places the least significant digit represents 1
µS. The
box around the least significant digit will be flashing to indicate that this digit can be
changed by pressing the up or down arrow keys. When this is set to the desired value
the right or left arrow keys can be used to move the flashing highlight to the other
digits, which in turn can be adjusted to the desired levels with the up or down arrow
keys.

When all digits are set to the desired levels press the Enter key to confirm the setting
and return the highlight to the left-hand side of the menu. Use the Escape [ESC] key
to return to other menu levels or the main measurement screen.
Calibration Reminder Set Up…
To ensure correct calibration at routine intervals a calibration reminder can be set for
the conductivity channel (and independently for the pH channel, see section 5.17).
The settings enable a variable time interval from 1 to 999 hours to be set. A visible
warning replaces the displayed reading when this time period has elapsed; it is also
possible to enable an audible warning if required.
Warning replaces conductivity reading when calibration id due
