Each Sensor/Transmitter has a Graph Scale for each of its channels, setting the upper and lower limits of any graph plots.

In Edit Mode there are two ways to set Graph Scale values:


Edit the Default Scale Values.

Note: Only Users with Administrator privileges or the User Chart Scale Configuration Permission assigned to them individually, inherited from an assigned Role or granted in addition to those inherited from an assigned Role can change the Default Scale Values.
It is recommended that a User Chart Scale Role is setup with the User Chart Scale Configuration Permission assigned to it and then assign the Role to all Users who may be required to alter Default Scale Values.


Use Auto Scale.

Default Scale Values Set in Edit Mode Will Be Used If:

The User has not set any Chart Scale values.

The User resets their scale to Default.

If a User is viewing a chart for the first time.

Note :Changing the Default Chart Scales in Edit Mode does not overwrite the Users' Chart Scale settings.

5.These panes shown above apply to this example; clicking on icons representing other parameters such as CO2 or Voltage will display windows appropriate to the selected parameter.

6.Enter the required Default Upper Scale and Default Lower Scale limits into the Default Upper Scale: and Default Lower Scale: fields respectively. See Figure 788 above.

Note:Graph Scale ranges can be set to be as narrow or as wide as required but, be aware that, if a Graph Scale range is set across a very narrow range of values and the Sensor starts to read outside of this range, nothing will be seen on the graph.

7.When you are happy with the new Default values, click on Save.

Click on the Back button to cancel any changes to the Default values.

If the Update has been successful, you will be returned to the Zone's Edit Mode window and the following message will be displayed. See 789 below:
