Description
Buffer Set
Sets the temperature compensated buffer set used for calibration—
•
Color Coded—4.01, 7.00, 10.01 (default)
•
IUPAC—4.01, 7.00, 10.01, 12.45
•
DIN—4.65, 9.23
•
IUPAC—4.01, 6.86, 10.01, 12.45

Custom Buffer Set (refer to
Table 2
)
Custom buffer sets are characterized at 25 °C (77 °F).
Buffer set values are shown on the Calibration Options screen.
Note: Only the minimum calibration points must be measured for DONE to
be shown on the calibration screen.
Buffer Set
Values
If the Buffer Set is set to Customer Buffer Set, sets the custom buffer set
(refer to
Table 2
).
Minimum Cal
Points
Sets the minimum number of calibration points necessary before a
calibration can be completed—1 (default), 2 or 3.
Slope Limit
Sets the slope limit—1% to 10% (acceptable slope criteria, default = 5%).
The slope must fall within set limits for successful calibration.
5.
Select Calibration Reminder and update the settings:
Option
Description
Reminder
Repeat
Meter will make an audible sound when a calibration is due and repeat the
sound at the selected interval—Off (default), 2 h, 4 h, 8 h, 2 d, 5 d or 7 d.
Expires
Calibration expires after the selected time—Immediately, Re
30 min, Re 1 h, Re 2 h or Continue Reading.
Note: The meter cannot be used to read samples after calibration has
expired unless Continue Reading is selected.

If prompted, enter a name for the new method settings. Additional changes made to
the settings of an existing method are automatically saved with the same method
name.
