User Guide
5. Always power off the microscope before exchanging scanners.
l
Before exchanging scanners, remember to first
motor the objective to its upper limit of travel.
l
Power off the controller before disconnecting the
scanner.
l
Exchange scanners and then power the controller
back on after the new scanner has been recon-
nected.
Note: Pay attention! On older Cyphers, exchanging
the scanner while the system is powered up can
damage the backpack electronics.
6. Make sure the scanner is fully seated against the chassis before locking in place.
l
Unlike the S scanner, which has a hard stop on the
back of the scanner, the ES scanner has a spring
loaded stop that needs to be fully engaged.
l
When inserting the ES scanner into the chassis, push
the scanner until you feel the spring on the back of
the scanner engage. Fully depress the spring until
you feel the hard stop.
l
After fully engaging the spring loaded stop at the
back of the scanner, lock the scanner in place.
Note: Proper seating of the scanner is most import-
ant when using the cooling capabilities of the
Cooler-Heater sample stage. During normal oper-
ation it is not particularly important.
7. Take care to properly set the correction collar on the objective.
l
The ES scanner uses different correction collar set-
tings than the S scanner.
l
The ES scanner uses 1.5 for gas operation and 2.0 for
liquid operation.
Note: Incorrectly setting the correction collar will
degrade the optical image quality. In addition it will
cause slight errors in the XY calibration of the scan-
ner.
8.3 Chemical compatibility
The ES scanner is equipped with FKM (Viton equivalent) O-rings in the factory. For cases where
viton is chemically attacked, please switch to the included FFKM (Kalrez equivalent) O-ring. These
rings can be found in a small box:
