2.3.2.2 Microprocessor-Generated Information 
Some  fields,  such  as  those  on  the  INSTRUMENT  STATUS  and  the  SYSTEM 
TEMPERATURES  screens,  contain  information  generated  by  the  microprocessor. 
The operator cannot affect the readings in these fields. (If you find that the cursor 
will not enter a field, the field contains microprocessor-generated information.) 
2.3.2.3 Exiting Without Making a Change 
If you decide not to make a change during this process, simply press the <Exit> 
key, and the values will return to the previous entries. 
2.3.3 Setting the Date and Time 
Before the instrument can be calibrated or collect data for regulatory use, the time 
and date must be set. Go to the INSTRUMENT MENU and select DATE and TIME. If 
they are not already set, use a 24-hour clock setting for the time and set the date in 
the day- month-year format. The instrument automatically runs an auto-zero cycle 
at midnight (unless BACKGROUND is set to DISABLED) each day according to these 
settings. See section 2.5 for instructions on programming menu entries.
