Place the magnetic tip above the switch symbol. Note that the selection changes to [Water 50C/
86F]. This is the next item on the [Select Liquid] option list. Keeping the tip over the sensor activates
an auto-repeat function to scroll the list automatically. Note that every trigger item changes to an-
other liquid on list (see paragraph 6.3 for the [Select Liquid] option list). Note that holding down on
either the <Up or Down Arrow> will cause the menu to scroll up or down (Auto Repeat Feature).

menu cell [Estimated Vs ] and that the second line shows the value: [1377]. This is the estimated

uid] to verify that the menu cell shows the new liquid selection.
A Note on Multiple Select Option Lists
Certain option lists allow you to make more than one selection. For example, the [Datalogger Data]
option list allows you to select any or all of the available data items for your reports. As previously
described, you can use and to move the cursor through the list. However, when you use
 to select
an item, the cursor moves to the next item in the option list. If you use  to return to the item that you
selected, you will see that an asterisk ( * ) appears next to that item to show that it is selected. Unlike
option lists that offer a single selection, the cursor remains within the option list so that you can make
other selections. To deselect a previously selected item, scroll to that item (marked by an asterisk) and
then use

.
After selecting all the desired items, use to leave a multiple select option list.
How To Enter Numeric Data
This section shows how to edit a numeric menu cell. The following example uses the [Pipe OD] menu
cell. The left-hand figure on the next page shows the [Pipe OD] menu cell. Notice that the second line
shows the current outer diameter value: [0.500]. (The “greater than” symbol placed before the param-
eter indicates that it is the current selection.) This example explains how to change the pipe outer diam-
eter to 4.500.
