Clean the tube
The sampler measures the sampling volume with two capacitive sensors. Based on the sampling point, dirt can
collect on the silicon tube. Refer to
If the message "Error sensor / error electrodes" shows, clean the tube as follows:
1.
Cut a piece of sponge of approximately 12 x 12 mm.
Note: As an alternative, buy a cleaning sponge. There are cleaning sponge balls with different diameters ready to use.
Make sure that the diameter of the sponge is more than the tube diameter. Refer to
Figure 2 Cleaning sponge
2.
On the sampler menu select
DIAGNOSTICS / TEST
>
COMPONENT TEST
>
PUMP
to manually operate the
pump in forward (suction) and backward (purging).
3.
Moisten the sponge and put it into the tube by using the tube suction. Then, alternatingly operate the pump in
the two directions.
The sponge collects the dirt on the tube.
4.
Repeat until the tube is clean.
5.
Remove the sponge.
