Research plusadjustable volume - adjustment to
environmental parameters
Adjustment change for specific liquid densities, changed altitudes or pipette tips
that are not used to calculate the random and systematic error.
The Research plus was adjusted, tested and fitted with a gray adjustment seal
with the abbreviation "ADJ" before delivery. The adjustment display on the side
reads "0". Changing the adjustment will change the volume by a specific value.
Strictly speaking, the change only applies to the testing volume.
Auxiliary equipment
• Supplied adjustment tool (order no. 3120 633.006)
• Supplied red adjustment seal (ADJ)
1. Remove the gray adjustment seal.
2. Keep the ejector pressed.
3. Insert the adjustment tool (from the delivery package).
4. Turn the adjustment tool until the adjustment display shows the desired value.
6. Carry out weighing procedures to check the accuracy and precision.
7. After the tests, close the opening with the red adjustment seal (from the
delivery package).
If the adjustment only applies to a specific liquid, mark the pipette accordingly.
Use the labeling area on the pipette and mark it with the liquid and the volume.
5. Place the Research plus on a horizontal
surface (table). When completing the
adjustment, look absolutely vertically at the
window and read the set value via the
backsight in the viewing window.
