4.0 Operation Guide |1
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.
