USER MODE CALIBRATION LINK
A new function has been added to the Ultrameter that makes calibration
of the unit while in "User" mode easier, and more repeatable and accurate
than other calibration methods. It is recommended that this calibration
method be used to provide the highest degree of confidence when the
Ultrameter is used in "User" mode.
A.
Calibration of Ultrameter for use in User Mode
1.
Press the
or
key to power up the Ultrameter.
2.
Calibrate the unit using a Standard Solution. Refer to
CALIBRATION in Operation Manual.
3.
Place the Ultrameter in User mode. Refer to SOLUTION
SELECTION in Operation Manual.
4.
Verify/Set the calibration link. (See below – Setting User Mode
Calibration Link).
B.
Setting User Mode Calibration "Link"
The link function sets or "links" the calibration gain factor of a Standard
Solution to the User solution mode. Once set, the "link" will stay intact
with future calibrations unless the link has been canceled. For more
information on canceling the User Mode Calibration Link refer to the
section below "Canceling User Mode Calibration Link". Follow the steps
below to set either the KCl, NaCl or 442 calibration factor to the User
solution mode.
1.
Press measurement key desired to be “Linked”, i.e.,
,
or
.
2.
Place the Ultrameter in User mode. Refer to SOLUTION
SELECTION in Operation
Manual for selecting the User
Mode.
3.
Press the
arrow key until
the menu "
Linc
" appears.

4.
Press the
key. The
instrument will display "
S E L
"
and the “
User
” Icon. Fig. 7.
Any additional display of KCl, NaCl or 442 icons indicates a link between
the User solution and the other solution displayed.
5.
Press the
keys to
select a Standard Solution to be
linked to the User mode
calibration constant.
(see Fig. 8,
User
linked to
KCl
).
N o t e
: If none of the Solution Selection icons are displayed (i.e. KCl,
NaCl or 442) nothing has been linked to User mode.
6.
Press the
key to accept the setting. Pressing any of the
measurement keys will exit without changing the setting. User
mode "link" is now complete. The User mode will now use the
calibration gain constant used for the calibration of the Standard
Solution as outlined above.
C.
Canceling User Mode Calibration "Link"
The Ultrameter must be in
User
linked mode in order to cancel the "link".
Refer to SOLUTION SELECTION in Operation Manual.
1.
Press “Linked” measurement key , or
.
Two solution icons will be shown the left side of display - “
User
”
and another, i.e., “
KCl
”.
2.
Press the
key until the menu "
Linc
" appears. Fig. 5.
3.
Press the
key, the unit will display "
S E L
" and the “
User
”
Icon.
