2.8 DATA ENTRY PROCEDURES USING THE RS-232 INTERFACE
The left-hand column shows the menu cells (described previously). Another way to look at left-hand
column items is to consider them menu questions. Then you can see that the right-hand column
answers these questions. Right-hand column answers can be:
z
Another series of menu cells (that become left-hand column items when selected).
z
An alphanumeric string (e.g., a site name).
z
An item from a scrollable option list (e.g., a class of liquids).
z
A numeric entry (e.g., a pipe outer diameter).
2.8.1 ENTERING ALPHANUMERIC STRINGS
An alphanumeric string is a series of numbers and letters including the Quotation Mark and the Pound
Sign symbols. You can also use a space. The meter uses these to identify a site setup or user-
modified table. Menu cells that use these strings provide an 8-character (max.) field for data entry.
Entering alphanumeric strings are easy since the 1020 responds to keys typed on your keyboard. The
following example uses the [Create/Name Site] menu cell. This is the first action required to begin a
new site setup. We will use the site name [SITE1]. See the screen below. Note that the right-hand
highlight is blank.
Press the <Right Arrow> to access the alphanumeric entry field. Note that the prompt changes to a
question mark (?). Use the PC keyboard to type: SITE1. Note that the letters are upper case without
you having to use the <Shift> or <Caps Lock> keys. (See menu screen on next page.)
