User can program the display to show information like 
Barr graph, Keyboard Beep Stability Beep and more.

User can choose if desire to have Barr graph shown 
above the Reading screen. When Bar Graph is 
displayed, the information about Sensibility and Sample
Temperature will not be displayed!

User can now adjust the Minimum and Maximum 
values for the Bar Graph. Refer to Page 12. 

User can choose if instrument would Beep when Stability 
is reached during Read Mode or Not.

User can choose if instrument would Beep on Keyboard 
touch or Not.

During this sequence, user will be able to choose alarms 
and also adjust it’s values. 
Will be able to choose if  RS232 is needed and if 
connected to a PC or a Printer.

Press
