CAUTION
Hot surfaces due to hot sample gases and high-temperature devices
Danger of burns due to surface temperatures above 70 °C (155 °F)
The inside of the oven reaches a temperature of approximately 200 °C during operation.
After being switched off, the device and its parts are still very hot and the temperature only
drops very slowly. You can call up the actual temperature of the oven and other
temperature parameters via the Diagnostic values (function 2) (Page 77).
Contact with skin may result in burns.
•
Wait until the device has cooled down before starting maintenance work or
decommissioning.
• Take appropriate protective measures during maintenance, e.g. contact prevention.
CAUTION
Electrostatic discharges
All electronic assemblies are equipped with highly integrated circuits or components. For
technological reasons, these electronic components are highly sensitive to overvoltage and
thus to discharges of static electricity.
Electrostatic sensitive devices (ESD) devices can be destroyed by voltages well below the
threshold of human perception. These static voltages develop when you touch a
component or electrical connections of a device without having discharged the electrostatic
charges from your body. The damage an assembly incurs due to overvoltage is often not
immediately detectable but rather becomes apparent only after an extended operation time.
To avoid damage from electrostatic discharges, take the following precautions:
•
Make sure all persons, workplaces and packaging are sufficiently grounded when ESDs
are being handled. This prevents electrostatic charge.
•
You should only touch ESDs if this is unavoidable. In such cases, handle the
assemblies without touching any chip pins or PCB traces.
•
If you must perform measurements on an assembly, discharge your body before
commencing work. Do so by touching grounded metallic objects. Always use grounded
measuring instruments.
CAUTION
Faults at the device
For faults which you are unable to eliminate, place the device out of service and protect it
against inadvertent commissioning.
