Phase 4: Bringing the instrument to a "ready to measure" state

Proceed as follows:

 Close the right side door (magnetic lock).

 Replace the carousel.

 Push the furnace back:

 Lift the bayonet catch (2) slightly so as not to damage the seal on the combustion tube

connection.

 Close the bayonet catch by turning the bayonet catch handle (1) to the left.

 Close the ground-in clamp (3) on the reduction tube.

 Push the heat cover onto the angle plates above the quartz glass bridge.

 Close the front door.

 Set the normal temperatures as the setpoint temperature of the furnaces. To do so, open the

"Instrument parameters" dialog in the operating software by selecting Options > Settings >

Parameters.

 Wait for the tubes to reach the correct temperature.

 Once the furnaces are stable, perform a leak test. See Performing a leak test (on page 242).

 The instrument is only ready to measure when the leak test is successful.

To be observed after maintenance

If you have performed maintenance work that has a defined maintenance interval, you must manually

reset the "Status" field to zero on the "Maintenance intervals" dialog (accessible via Options >

Maintenance > Intervals. See Defining maintenance intervals in the software (on page 170).
