• Open – Open an existing trend chart

• Delete – Delete an existing trend chart

• Save – Save any changes made to the

current trend chart

• Save As – Save the current trend chart

as a new trend chart

Open and Delete will display a screen where

the user can select the trend chart to open or

delete. Save will automatically save the

changes to the currently opened trend chart.

Save As will let the user enter the name of the

new trend chart.

The three buttons below the list of trend items

will allow the user to modify individual trend

items:

• Add – Add a new trend line to the trend

chart

• Edit – Edit an existing trend line in the trend

chart

• Delete – Delete an existing trend line in the

trend chart

Add and Edit will display a screen (shown) where the

user can set up the trend line. Delete will delete the

selected trend line from the trend chart.

• Name – This is the name of the trend line.

Note – since space is limited, it is

suggested that the trend lines be named

with least understood characters, i.e., “Prb

1” instead of “Probe 1”

• Data – This is the data from the data log data.

Descriptions are used to make the selection of

data easier. If no description is provided, the register number is provided

• Min – This is the minimum value for the scale of the data

• Max – This is the maximum value for the scale of the data

• Expression – The expression to display the data with the correct scaling. Data in the registers

does not have any scale. For instance, T/C data will require the “x*0.1” expression to display the

T/C values properly. Trend lines that do not require any scaling will just need an “x” as the

expression. Probe values do not need scaling

• Format - the value displayed on the chart display of the operator interface. A short custom

description can be added here. For example, to display one (1) decimal point, enter a value of

“#0.0”. For carbon values, enter a value of “#0.00” for 2 decimals. This would display a value

like “0.81”. Entering “#.00” would display a value of “.81”

• Units – The type of units to be displayed

• Line Width - A numeric value for the thickness of the trend line. A 1 is a thin line; A higher value

= thicker line width

• Sample – This will allow the user to test the expression to verify that the expression is set up

properly. Enter the test value and press the Test button to see if the expression displays the value

properly. For instance, if the “x*0.1” expression is used and “1500” is entered, then the result

would display “150”

Press the Set button to confirm the changes made. Pressing the Cancel button will not set any changes.

Return

This option will return the user to the Menu screen.
