CALIBRATION
Each Ovation pipette is factory calibrated to manufacturing specifications at 21.5˚C
(±2˚) using distilled water. It is recommended that performance be verified at least
every six (6) months, when internal maintenance has been performed, or on an as-
needed basis.
The Ovation pipette can be easily in-lab calibrated ±10% for optimum performance
for your operating conditions. In addition, the calibration factor can be pre-determined
and set at the appropriate value for a liquid to be dispensed. Changing the calibration
factor is quick and easy. Returning the calibration factor to 1.000 will re-set the
Ovation pipette to its original factory calibration.
Prior to performing calibration procedures, “home” the plunger by simultaneously
pressing and holding the and buttons until appears on the LCD.
Depress the plunger to the first stop, and release it. Then depress the plunger to
the first stop again and hold until three “beeps” are heard.
For optimum performance over the entire pipetting range, verify and calibrate the
pipette using the maximum volume setting. Note: Unless using a specific liquid at
one volume, always verify and calibrate at the maximum volume.
With the pipette set to the desired volume, determine the actual volume dispensed*.
Then use the Ovation’s calibration function to determine the appropriate calibration
factor.
It is recommended that whenever the calibration factor is changed from the factory
setting, that the current factor be recorded on a calibration label on the base of the
pipette. The user may also wish to record the new factor in the laboratory’s quality
control log.
