3 About the product
Esco Medical AVT-1®is an anti-vibration table, intended to be used with high-
magnification microscopes. It isolates the microscope from vibrations generated in the
room where the table is placed and from vibration generated above or below any part of
the table top, that is not part of the AVT platform.

AVT-1® User Manual Rev. 1.8
9
The table consists of a sturdy frame and a tabletop in stainless steel and glass. The
AVT platform is located in the middle of the tabletop and it is floating on the AVT mech-
anism.
The anti-vibration mechanism works as a passive damping device and only partially
damps the vibration that is generated on the AVT platform itself.
The microscope must be placed on the anti-vibration float.
In all buildings, floors vibrate at low frequencies that may affect the performance of
high-magnification microscope. The effects of vibration can be greatly reduced by in-
stalling a system that isolates the microscope area. The degree of improvement varies
between instruments and locations, depending on the amplitude and frequency of floor
vibrations.
This product does not carry a CE mark. Only those product categories that are subject
to specific CE marking directives are required (and allowed) to carry CE marking. There
are no such categories or directives that would include a non-electrical anti-vibration
table as AVT-1®. The product is manufactured under ISO 9001 Quality Management
System.
Personal Protective Equipment (89/686/EEC) and Machine Directive (2006/42/EC) is
not applicable for AVT-1®.

Do not touch the springs or contact points with bare hands. Skin grease will
compromise the performance of vital friction points.
Place the anti-vibration table in an appropriate place on the floor.
Level the table plate horizontally by adjusting table legs with a spanner. In order to en-
sure a good result, place the level on a table plate.
Figure 7.1 Leveling table legs
Put on gloves.
Install the springs into the holes at the front and the back of the table.
A 3rd spring, placed in the centre, may be supplied for the use of a very
heavy microscope. In most cases of normal usage, it is better to mount front and
back springs only.
Figure 7.2 Equal distance from the hole
The float part labeled 1 should be placed on the springs and there should be equal dis-
tance left from the hole on all sides, in order to have space for centering the floating
plate. The holding screws should be facing up.

AVT-1® User Manual Rev. 1.8
12
Figure 7.3 No contact between the floating plate and the table
It is very important that there would be no contact between the floating plate and the
table. Then place the float element 2 on the top of float element 1.
Figure 7.4 Rubber stops facing up
The rubber stops should be facing up. Leave equal distance from the hole on all sides
of the table plate.
Then place the top of the floating element (stainless steel) on the rubber parts again,
leaving equal distance from the hole on all sides of the table plate.
Figure 7.5 Float element is placed too high
The float element should be level with the table top. In the picture above it is too high.
The adjustment can only be done after the microscope has been placed on the float, as
the weight will push it down.

AVT-1® User Manual Rev. 1.8
13
It is the fully laden float that should be level, thus the adjustment is dependent on the
microscope weight.
The float height is adjusted by loosening 4 securing hexagonal head bolts and turning
the handle.
Figure 7.6 Adjusting the float height
After adjustment, tighten the four securing bolts again. If this is done improperly, the
table will go out of adjustment while in use.
Any additional equipment may now be installed.
Make sure that all cables that are connected to the microscope hang freely between the
attachment point on the microscope and the other side. This can be achieved by strip-
ping the cable to the points and making sure that the cable forms an arch between the
points. If the cable is tight or touches area between the anchor points, vibration may be
transferred via the cable.
After successful installation and device testing, complete user training and instructions.
8 Cleaning instructions
Always perform cleaning procedures locally; for more guidance consult ei-
ther your manufacturer or the distributor.
Switch off the devices on the table and remove the mains leads. Clean the surfaces of
AVT-1®with a 70% alcohol solution, using a lint-free cloth.
A list with approved cleaning liquids can be supplied on request.

9 Maintenance
Esco Medical AVT-1®is designed to be easy to use and requires almost no mainte-
nance at all.
Over time, adjustments may become necessary.
The rubber paste should be changed every 2 years, the springs –every 6 years.
Warranty is considered to be void if service and maintenance procedures
are not followed.
Warranty is considered to be void if service and maintenance procedures
are done not by a trained and authorized personnel.
10 User troubleshooting
Table 10.1 Heating system
Vibrations
Cause
Action
The float is touching the table
plate and vibrations are trans-
ferred directly to the microscope.
The floater should be in the
centre position of the hole.
Air should be all around the
floater.
Loose tightening bolts.
Tighten four tightening bolts.
The spring system is not
painted and has to be
completely grease free to
function.
The surface is made to be
rough intentionally.
Grease or oil on the surface of
contact points.
Clean the area with 70% al-
cohol.
Tight cables of micro-
manipulators or any other
equipment that are placed
on the table top will result
in vibrations being trans-
mitted directly to the mi-
croscope.
Cables routed incorrectly.
Tie cables so that they would
not touch the table and would
hang loose between the at-
tachment points.
Microscope is placed unevenly
on the floater.
The weight of the microscope
has to be distributed evenly
on the floater. Since the back
part of a microscope is the
heaviest, it should be moved
more to the front of the table
plate.
