The adapter of the robotic arm should now be located in the opening of the deflector, as shown in the following figure. This is the position where the pipetting tip is to be stripped by moving the lift upwards. It is very important that the adapter perfectly fits into the opening of the deflector.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 3.20 Mounting the safety shield 5 Strip the pipetting tip ￭ ￭ Switch to the Move tab. Under Lift position, select Work position as Target position and press [Start]. The lift moves upwards. Thereby the pipetting tip is stripped. It drops into the collection container. If the stripping of the pipetting tip does not work, then the individual positions must be adjusted once again. Note Have one method with a weighing and pipetting sequence run through.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 3.21 Connecting MSB devices Caution Exit the control software before you plug MSB instruments in. The control instrument recognizes when it is switched on which instrument is connected at which MSB connector. The operating unit or the control software enters the connected MSB devices into the system configuration (Device manager). MSB connections can be extended with the 6.2151.010 cable. The length of the connection must not exceed a maximum of 15 m. 3.21.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 4 Handling and maintenance 4 Handling and maintenance 4.1 General The 864 Robotic Balance Sample Processor requires appropriate care. Excess contamination of the instrument may result in functional disruptions and a reduction in the service life of the sturdy mechanics and electronics of the instrument. Severe contamination can also have an influence on the measured results. Regular cleaning of exposed parts can prevent this to a large extent.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 5 Troubleshooting 5 Troubleshooting 5.1 Robotic arm Problem Cause Remedy The robotic arm moves all the way outward and buzzes. Sample Processor – The Swing Head is not correctly configured. In the control software under "Configuration" (or under "Device manager" for Touch Control), enter the correct value for the Swing offset. Sample Processor – Robotic arm is wrongly mounted. Disconnect the mains plug and dismount the robotic arm.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 5.3 Pipetting tips Problem Cause Remedy The results are spread widely. The weighings are not correct. ￭ ￭ ￭ 5.3 Readjust the weighing plunger (see "Adjusting the weighing plunger", page 53). Correct the position of the balance (see "Centering the weighing column", page 52). Adjust the leveling of the sample beakers in the weighing pans. Pipetting tips Problem Cause Remedy The pipetting tip is dripping. The pipetting tip does not rest close on the adapter.
