3. Press
CFM
to confirm calibration. The instrument displays the calibrated value and the second
expected standard.
4. After the first calibration point is confirmed, immerse the ISE electrode approximately 4 cm
(1½”) into the second calibration solution.
If necessary, press the / keys to select a different standard value.
The “ ” tag is displayed blinking until the reading has stabilized. When the reading is stable
and within range of the selected standard, the
CFM
functional key is displayed.
5. Press
CFM
to confirm calibration. The instrument displays the calibrated value and the third
expected standard.
6. After the second calibration point is confirmed, immerse the ISE electrode approximately
4 cm (1½”) into the third calibration solution.
If necessary, press the / keys to select a different standard value.
The “ ” tag is displayed blinking until the reading has stabilized. When the reading is stable
and within range of the selected standard, the
CFM
functional key is displayed.
7. Press
CFM
to confirm calibration. The instrument displays the calibrated value and the fourth
expected standard.
8. After the third calibration point is confirmed, immerse the ISE electrode approximately 4 cm
(1½”) into the fourth calibration solution.
If necessary, press the / keys to select a different standard value.
The “ ” tag is displayed blinking until the reading has stabilized. When the reading is stable
and within range of the selected standard, the
CFM
functional key is displayed.
9. Press
CFM
to confirm calibration. The instrument displays the calibrated value and the fifth
expected standard value.
10. After the fourth calibration point is confirmed, immerse the ISE electrode approximately
4 cm (1½”) into the fifth calibration solution.
If necessary, press the / keys to select a different standard value.
The “ ” tag is displayed blinking until the reading has stabilized. When the reading is stable
and within range of the selected standard, the
CFM
functional key is displayed.
11. Press
CFM
to confirm calibration. The instrument stores the calibration value and returns to
measurement mode.
Note:
The instrument will automatically skip the standard solutions used during calibration.
Four-, Three-, Two- or One-Point Calibration
1. Follow the steps described in Five-Point Calibration procedure.
2. Press
ESC
or
CAL
key after the appropriate accepted calibration point. The instrument stores the
calibration data and returns to measurement mode.
