Calibration Mode:
In Calibration Mode, the user enters the % errors calculated in the initial Verification Procedure. Once these values are
entered, the unit will calibrate automatically.
NOTE: The upper LED indicates the current calibration status. Solid blue
indicates factory calibration, while solid white indicates user calibration
values have been stored.
Step 1 - Enter Calibration Mode
1 Set the volume dial to BELOW 0.0 mL.
2 Hold the ali-Q 2 upside down.
3 Press and hold the aliquot button for 5 seconds. Three tones will sound to indicate entry into calibration mode and
the lower LED will be quickly blinking blue .
4 Release the button and return the unit to upright orientation.
5 Watch for the lower LED to blink blue before proceeding.
NOTE: Calibration mode can be exited, without saving changes, during step 2 or step 3 by quickly pressing and
releasing the aliquot button . This will be followed by 5 red LED flashes to confirm exit.
Step 2 - Enter the % error at 0.5 mL
After entering calibration mode, the lower LED will be quickly blinking blue . This indicates that the unit is ready to
accept the calculated error at 0.5 mL.
1 Enter the 0.5 mL % error value, from the previously performed Verification Procedure by setting it on the volume
dial. For example, if the mean error is 1.5%, set the volume dial to 1.5.
2 If the ali-Q 2 is dispensing too high (+1.5% error), press the Aspirate button to
save the changes. If the ali-Q 2 is dispensing too low (-1.5% error), press the
Dispense
button to save the changes. The 2 LEDs will alternate
blue
5 times,
accompanied by a tone, to confirm entry.
3 Wait until the lower LED is blinking blue before proceeding.
Step 3 - Enter the % error at 5 mL
The lower LED will now be slowly blinking blue , indicating that the unit is ready to accept the calculated error at 5
mL. Repeat the process outlined in Step 2 with the previously obtained 5 mL % error value. The 2 LEDs will alternate
blue 5 times, accompanied by a tone, to confirm entry
.
(Note: If the LEDs blink YELLOW, the calibration values are out of bounds (+/-10%) and the values will not be stored.
Call our Technical Application Specialist at 914-244-4068 for assistance.)
If the LEDs blink GREEN, the unit has been successfully calibrated. The unit will now return to normal operation.
A post-calibration Verification should always be performed to confirm the changes were successful and the ali-Q 2
accuracy should now be within spec.
Reset to Factory Calibration:
The ali-Q 2 has been calibrated from the factory to ± %2 at 0.5 mL and 5 mL. The user can easily revert to the factory
calibration at any time. To reset the unit:
1 Enter calibration mode using Step 1 in the Calibration Mode section.
2 Turn the ali-Q 2 upright.
3
Press and hold the aliquoting button for about 5 seconds, until the LEDs begin to blink
green
.
4
Release the button. The LED will blink
green
5 times to confirm the factory reset has been applied.
