LAST ISE CALIBRATION DATA
Last ISE calibration data is stored automatically after a successful calibration.
To view the ISE calibration data, press 2nd then GLP key while in ISE
measurement mode.
The instrument will display the date (yyyy.mm.dd) of the last calibration
as in pH GLP mode.
Press the ARROW keys to view the next logged calibration parameter
(pressing the key):
• The ISE calibration time as in pH GLP mode.
• The ISE calibration slope (mV/decade) on the primary LCD and the ion
charge on the secondary LCD.
• The first ISE calibration buffer on the primary LCD and the corresponding
mV value on the secondary LCD.
• The second ISE calibration buffer on the primary LCD and the corresponding
mV value on the secondary LCD.
Notes: • If a one-point calibration is performed after a two-point
calibration, the instrument will keep the old slope.
• If “no bUF” message appears on the LCD, the instrument
informs you that calibration was performed in only one point.
• The instrument ID as in pH GLP mode.
