Section 3  Controls and Indicators 

 

Pictures of the display and controls are shown at the rear of this manual. 

3.1 

Bargraph and exponent 

The bargraph and exponent indicate the leak 
rate in terms of the selected units. For 
example, a leak rate of +6 x10-4 ml/sec would 
appear as shown opposite. 

3.2 Zero

3.3 Units 

Press 

ZERO

 and 

GAS GROUP

 together to step 

through the available units of measure to set the one 
desired. The correspondence between leak rate 
settings depends on the sample flow rate. If accurate measurements are required the 
instrument should be calibrated in the same mode as it will be used. 

3.4 Peak

indication remains unaffected. 

3.5  Gas group button

 

Use this button to see and select the required gas group.  
Upon pressing the button, the display will blank except for the 
Leak Rate Exponent which shows the current gas group.

through the gas groups 1 to 4. 

To keep the current gas group, press the button again immediately.  To select a 
different gas group, press the button again when the required group number is visible. 

The gas groups, and thermal conductivities, are listed in Section 8.
