Initial self test

After switching on the TG

RADIENT

 the serial number of the instrument and the software version

is displayed.

                   TGradient

             Serial No 1234567

Vers. 4.00 op

The TG

RADIENT

 checks all programs in all directories (so called RAM check).

Handling of the adjustable heated Lid

To achieve optimum pressure on the tubes the TG

RADIENT

 is equipped with an height adjustable

heated lid. 

Close the lid:

After the samples have been placed in the block close the lid. Turn the wheel clockwise until you
hear a clicking noise. In this mode the pressure will not increase further, even when you keep on
turning the wheel. 

Note:

The pressure of the lid has been optimize for a fully loaded block. If only very few tubes

are loaded to the block you should place dummy tubes in the four corner positions to avoid
damage of tubes by excessive pressure.

Open the heated lid:
First: 

Release pressure by turning the wheel counter clockwise. As soon as there is no more

resistance the pressure has been released. 

Then: 

now you can open the lid with the knob.

Important:

 The lid should not be opened under pressure because this leads to damage of the

locking mechanism.
