Setting a User Defined Graph Scale

Contents

Setting the Graph Scale

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

There are three ways to scale a graph:

•Use the Default Scale (See Default Calibration Values).

•Use Auto Scale.

•Use a User Defined Graph Scale as set here.

To Set a User Defined Graph Scale

1.Access the Calibration property entries as outlined in: Editing a Sensor's Calibration Settings.

2.Click the on the Temperature or Humidity icon to display the Temperature or Humidity window for the selected Sensor/Transmitter. See Figure 408 below.

3.Enter the required upper and lower Graph Scale limits into the Upper Scale: and Lower Scale: fields respectively. See Figure 408 below:

Setting the Graph Scale

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.

4.Select Update to confirm the details.

•If the Update has been successful, the following message will be displayed. See 409 below:
