• The calibrated value will be displayed on the
primary LCD and the second expected standard
value on the secondary LCD, together with “CAL”
and “Cal Point 2” tags.
Note: The instrument will automatically skip the standard solution used for
the first point.
• After the first calibration point is confirmed, immerse the ISE electrode
approximately 4 cm (1½”) into the second calibration solution.
• If necessary, press the ARROW keys to select a different standard value.
• The “ ” tag will blink on the LCD until the reading is stable.
• When the reading is stable and close to the selected standard, the “CFM”
tag blinks.
• Press CFM to confirm calibration.
• The calibrated value will be displayed on the
primary LCD and the third expected standard
value on the secondary LCD.
• After the second calibration point is confirmed, immerse the ISE electrode
approximately 4 cm (1½”) into the third calibration solution.
• If necessary, press the ARROW keys to select a different standard value.
• The “ ” tag will blink on the LCD until the reading is stable.
• When the reading is stable and close to the selected standard, the “CFM”
tag blinks.
• Press CFM to confirm calibration.
• The calibrated value will be displayed on the
primary LCD and the fourth expected standard
value on the secondary LCD.
• After the third calibration point is confirmed, immerse the ISE electrode
approximately 4 cm (1½”) into the fourth calibration solution.
• If necessary, press the ARROW keys to select a different standard value.
• The “ ” tag will blink on the LCD until the reading is stable.
• When the reading is stable and close to the selected standard, the “CFM”
tag blinks.
• Press CFM to confirm calibration.
• The calibrated value will be displayed on the
primary LCD and the fifth expected standard
value on the secondary LCD.
• After the fourth calibration point is confirmed, immerse the ISE electrode
approximately 4 cm (1½”) into the fifth calibration solution.
• If necessary, press the ARROW keys to select a different standard value.
• The “ ” tag will blink on the LCD until the reading is stable.
