CHANGING DISPLAY FORMAT

The Model 340 lets the user decide which information is shown on the display. This section discusses the
display fields that can be configured using the Display Format key.
4.5.1

Number of Readings Displayed

The Model 340 can display between one and eight input readings at a time. If one to four readings are
chosen, they will be shown with the large characters. If five to eight readings are chosen, they will be shown
with small characters.
To change the number of display readings, press the Display Format key. You will see the Reading Display
Format screen with the current number of Input Displays highlighted. Use a number key or the s or t key
to select the desired number of reading displays, then press the Enter key. The lower portion of the setting
display will now show the available display fields ready for the operator to enter a sensor input and reading
source. The default setting is 2.

Sensor Input

The Model 340 has two sensor inputs, A and B. More sensor input can be added with Model 340 options.
Input A can be used to monitor more than one sensor with the use of an external scanner. Scanner support is
covered in Paragraph 5.4.
To select a sensor input for a display field, press the Display Format key. You will see the Display Format
screen with the current number of Input Displays highlighted. Use the Enter or Next Setting key to select
the display number, then use the s or t key to select the desired input. Then press the Enter key. A sensor
input can appear in as many reading fields as desired. The default setting is A and B.
