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.
