4.6.4 Carry out determinations
Select method
The determination method is selected in the Method field in the control
window.
Different methods with different temperatures can be selected for Block
A and Block B. In contrast, the gas flow which is defined in the method
loaded for Block A also applies to Block B.
By clicking on the method parameters (see section 4.5.2) can be
altered as required.
Switch on heating
The heating of the two blocks A and B to the temperature set in the
method can be switched on individually for each block. This is done by
clicking on the following button.
As soon as the heating is switched on the color of the frame of this
button switches to red. At the same time the temperature display 99
"TEMPERATURE" on the 763 PVC Thermomat starts to blink for the
selected block.
If this button is clicked on again during the heating-up phase then the
heating will be switched off.
The actual temperature is shown digitally beside the button. A bar be-
low shows the absolute variation of the actual temperature from the tar-
get temperature; the bar length corresponds to 50 °C.
When the selected temperature has been reached the temperature dis-
play 99 "TEMPERATURE" stops blinking and the LED remains lit up. At
the same time the color of the frame of the button switches to green.
The block is now ready for receiving the samples and starting the de-
termination.
If this button is clicked on the heating is switched off.
