5.1 Troubleshooting
5.1.1 No movement
•
Check Scientifica logo is illuminated on the front of the rack
•
Check all cables and connectors for damage or loose
connections
5.1.2 Drift
•
Allow the system to warm up
•
With most electrical components on the rig needing a warm-up
period, it is good practice to allow a certain warming-up time
after switching on the power of the set-up (up to one hour).
•
Check all bolts are tightened
•
Is the Headstage or probe holder attached correctly?
•
Make sure that the headstage is firmly attached
•
Be careful that you don’t over tighten the clamp, because this
may cause expansion and may also be a source of drift.
•
Check that the headstage-mounted sliding bracket is
clamped at the end of its travel.
•
Is the pipette holder attached firmly and the O-ring new and of
appropriate size?
•
With pipettes being exchanged very often, there is a lot of
wear on the O-ring inside the pipette holder which may lead
to it not holding the pipette firmly.
•
Also make sure that there is no tension on the pipette suction
tube
•
Ensure that the AgCl wire inside the pipette is not touching
the front end of the electrode.
•
Are the 3 linear stage wires and the rotation sensor wires
supported?
•
There should be a soft loop on all wires from the manipulator,
ideally fixed to a point close to the manipulator mount.
•
The cables can also be fixed to the Faraday cage above the
manipulator, but only if the Faraday cage is isolated from the
floor.
