in the display to calibrate at three points. The value for distilled water is predefined at 0
mOsmol/kg.
Selection of a first calibration point (c1):
With
choose
,
select the calibration value of the
calibration standard to be used for the first calibration point >

. Confirm your selection with
OK
.
The system automatically specifies
the first possible second calibration point.
Selection of a second calibration point (c2):
Use
choose
, to change the defined calibration
value to the calibration standard to be used for the second calibration point. Confirm your selection
with
OK
.
)
Note: The following applies for 'c2': the minimum distance from c1 is the calibration point
after next. For example:
If 'c1' = 100 mOsmol/kg, all calibration points above 300 mOsmol/kg are possible for 'c2'.
If 'c1' = 200 mOsmol/kg, all calibration points above 500 mOsmol/kg are possible for 'c2'.
If 'c1' = 300 mOsmol/kg, all calibration points above 600 mOsmol/kg are possible for 'c2'.
…
If 'c1' = 2000 mOsmol/kg, 3000 mOsmol/kg are possible for 'c2'.
The following display >
sample sequence
shows
0 0 c1c1 c2c2,
the sequence for placing the distilled
water (0), the first calibration standard (c1), and the second calibration standard (c2) in the sample
holder. Select
OK
to accept the settings. With
Cancel
you can discard the settings and return to the >
calibration
display.
You will now be prompted to insert the sample holder in the unit.
The Osmomat auto automatically detects the inserted sample holder and begins the calibration.
The calibration values are now shown consecutively on the display. If the printer is switched on, these
values are also printed. After successful calibration, the message >
accept calibrationmeas.?
appears.
Confirm the calibration values with
OK
. The unit then automatically prepares for sample measurement.
Otherwise select
repeat
to discard the calibration values and recalibrate the unit.

Note: Prior to the calibration procedure, switch the printer on to document the calibration
results. Subsequent display or printing is not possible!
