Leica MATS – Description 3
MATS = Microscope-stage Automatic
Thermocontrol System
The Leica thermocontrol system MATS is a heating system for
microscopes and stereomicroscopes and allows the viewing of
sensitive microscopic specimens under accurate temperature
conditions.
The present user manual describes the assembly and
operation of the Leica thermocontrol system MATS.
Your instrument is supplied with a printed user manual in
English.
Additional languages and information can be found on the inter-
active CD-ROM that is supplied with your Leica stereomicro-
scope or macroscope. User manuals and updates are available
for download on our homepage at www.stereomicroscopy.com.
Detailed information about the microscope, stereomicroscope
or macroscope can be found in the separate user manual to
each instrument.

Description

Before assembling and commissioning the Leica
thermocontrol system MATS, read the present user
manual and observe all safety notes.
Adhere to general and local regulations relating to accident
prevention and environmental protection.
The Leica thermocontrol system MATS is constructed in
accordance with the latest technologies and is provided with a
statement of conformity with EC requirements.
The Leica thermocontrol system MATS is a heating system for
microscopes and stereomicroscopes and intended for viewing
sensitive microscopic specimens under accurate temperature
conditions. The thermoplate heating stage can be heated up to
50 °C.
The Leica thermocontrol system MATS consists of a control
unit, a power cable and various thermoplate stage types for
Leica stereomicroscopes (transmitted light stands) and micro-
scopes (upright & inverted). Thermoplate and control unit are
matched to each other.
Always use thermoplate and control unit from the same
packaging, never from different packagings.
If the Leica thermocontrol system MATS differently than
described in this user manual, it may lead to personal injuries or
property damage.
• Do not fit different plugs or cables.
• Do not change or convert the Leica thermocontrol system
MATS.
• Do not dismantle any part of the motor-focus system unless
instructions for doing so are given in the user manual.
• The Leica thermocontrol system MATS may not be opened
and maintained by unauthorized personnel.

Leica MATS – Safety concept
The Leica thermocontrol system MATS may only be used in
closed facilities. The following installation sites must be
excluded:
• Where flammable gas, corrosive gas oil mist and particles
that can deteriorate electrical insulation are generated or are
abundant.
• Where highly intense vibration or impact is generated or
transferred.
• Near high voltage power lines or where inductive interfer-
ence can affect the operation of the Leica thermocontrol
system MATS.
• Sites which create condensation water or humidity or are
exposed to direct sunlight.
The process value displayed at the control unit corresponds to
the temperature of the table surface. If the specimen in a petri
dish or on a slide glass indicates a lower temperature
compared to the displayed process value, adjust the set value
to obtain a proper specimen temperature. Otherwise, the
specimen could be damaged.
If the sensor malfunctions, the surface may become
very hot.
•Dielectric strength: 2 sec. at 1350 V AC between power
supply terminal and ground terminal
•Insulation resistance: 500 V Mega more than 100 MΩ
minimum between power supply connection and ground
connection
•Fire protection: Temperature cannot be set higher than 50 °C
•Fuse: T AC250V 1.6 A
•The Leica thermocontrol system MATS is electromagneti-
cally compatible in accordance with the directive 89/336/EEC
and can be operated at the same time as other electrical
appliances.

Protective measures

Safety regulations

Ensure that
• the Leica thermocontrol system MATS is operated, main-
tained and repaired only by authorized and trained personnel.
• the operating personnel has read and understood this user
manual for the stereomicroscope or microscope and particu-
larly all safety regulations and applies them.
• Repairs may be performed only by service technicians
trained by Leica Microsystems.
• Only original Leica Microsystems spare parts may be used.
• Disconnect the power supply for maintenance and repair
work, otherwise there is a risk of injury through electric
shock.
• Only use the power cables listed on page 16.
• Inspect the power cable regularly for damage. If it is defec-
tive, replace it immediately, because it could cause the
instrument and ancillary equipment to become energized and
thereby endangering personnel.
• Observe proper cable routing so that no one can become
entangled in it or fall over it. The instrument could tip over
and be damaged.
• Avoid pulling at the power cable.
Be careful when handling liquids. Spilled liquids on electrical
devices can energize the instrument and ancillary equipment,
possibly causing personal injuries or damage to instruments.

Leica MATS – Safety concept
Cleaning, care Handle your Leica thermocontrol system MATS with care and
avoid anything that may scratch the thermoplate.
• Disconnect the power cable before cleaning the instrument.
• Never open or dismantle the control unit.
• Respect the warning signs relating to the handling of liquids.
• Do not soak into water or into solvent.
• Never use any solvents such as gasoline or thinner to wipe
the instrument. The color of the surface could change or
flake, or imprinted characters could be removed.
In case of dirt accumulation, carefully clean the control
unit and thermoplate with a soft piece of cloth moistened
with a solution of neutral cleaning agent dilluted in water.

Press the power switch (1).
When you finish operating, turn off the power switch and
disconnect the plug of power supply cord.
The thermoplate heating stage can be heated up to 50 °C.
The process value displayed at the control unit corresponds to
the temperature of the table surface. If the specimen in a petri
dish or on a slide glass indicates a lower temperature com-
pared to the displayed process value, adjust the set value to
obtain a proper specimen temperature. Otherwise, the spec-
imen could be damaged.
With stereomicroscopes it must be ensured that the
existing glass insert is removed from the base before the
heating stage is placed. Otherwise, the correct tempera-
ture is not guaranteed.
To adjust the temperature, press the Up/Down keys. When the
key is pushed for 1 sec or more, the indicated temperature
changes continuously. 2 seconds after above adjustment, the
temperature controller starts operating to obtain set tempera-
ture.
Set the temperature control to the desired temperature using
the keys (2).
Wait 10 minutes until the temperature of the thermoplate
stabilizes.
