Description

KEYBOARD

At each touch of button will be generated short beep when
the key does not have any significance at the moment, mid-
length beep for value change and moving in menu and longer
beep for confirmation of value changes.

ERRORS

At error occurrence will be generated sound signal of the
error. Three consecutive longer beeps in case of an error and
in case of a fatal error with repetition every 5 s. Repetition
can be interrupted by pressing any key.

WARNINGS

At warning occurrence will be generated sound signal of
warning. Three consecutive shorter beeps.

OPERATIONS

During operation will be generated longer beep and for long
operations may be this beep generated at the beginning and
at the end of an operation.

6.2.5. Cooling

Setting method of cooling is essential for detector drift and less essential for its noise. Final

result of its behavior is always dependent on surroundings and therefore needs experimental
attestation for given environment. It is necessary only for reaching the best result in highly sensitive
applications. For common use, the default setting is sufficient.

Lower rotation speed of fans decreases the noise (sound) level in laboratory, but increases

working temperature of illuminator. The lower the illuminator temperature is, the better is the
stability and working parameters of the unit. Recommended range of working temperature is
30-50

°C.

Diagnostics of cooling status is done in

Menu/Diagnostic/Cooling

, where are displayed actual

measured values of cooling system.

6.2.5.1.

Fans Mode

Here can be set method of optical block cooling using fans. Selectable options are

OFF,

CONSTANT VOLTAGE, CONSTANT SPEED

and

CONSTANT TEMPERATURE

.

Mode OFF Total shutoff is not recommended. Setting of these modes is preceded in further

points.

6.2.5.2.

Fans Voltage

Fans are controlled by constant adjustable voltage (default value is 8 V). Suitable for air-

conditioned laboratories, most stable fans run, but it is impossible to reach lowest rotation speed.
Default mode is cooling.

6.2.5.3.

Fans Speed

Here can be set constant speed of fans (default value is 4000 rpm). Setting is a sum of

rotation speed of both fans. Suitable for reaching very low rotation speed. Speed control can cause
slightly unstable run.

6.2.5.4.

Illuminator Temp

Constant illuminator temperature is maintained by variable rotation speed of fans. However,

they can cause higher detector noise, which can slightly react to rotation speed regulation. For not
