? Either double-click the Interval (ms) field in the monitor settings pane, or select the Interval command in the Monitor menu or in the context menu of Monitor Settings. or An Interval (ms) dialog box is presented with the present value shown in its edit field. Edit or enter a new (integer) value and click OK. If you want to cancel the operation, click the Cancel button. The new value is shown in the monitor settings pane. There are restrictions about the interval: ? The value must be an integer greater than zero. ? The value cannot be bigger than the current x-axis length in milliseconds. ? If monitoring mode is normal, the value must be at least 10. ? The value must not be too small related to x-axis length, i.e., x-axis length in milliseconds divided by the value must not exceed 32700. ? X-axis length in milliseconds must be multiple of the value. For example, if x-axis length is 1 second, interval 3 ms is not acceptable. You must then either fix the x-axis length or use another interval. Trends DriveWindow 2 6-23 If the value is invalid, an error message is displayed, when you click the OK button. You have to acknowledge the error message and edit the invalid value or cancel the operation. If the monitoring mode is normal and you have entered a value less than 10, an error message is displayed, when you click the OK button. You have to acknowledge the error message change the value to at least 10 or cancel the operation. Trends 6-24 DriveWindow 2 If you have entered value that is not acceptable because of the current x-axis length and/or history buffer size, you have the option to fix the x-axis length and/or the history buffer size. If you click Yes, your interval is accepted, but the x-axis length and/or history buffer size is changed, too. See Also: Common Trend Settings Restoring Default Settings Setting Monitor Monitor and Dataloggers Monitor Settings Monitor Menu Context Menu of Monitor Settings 3.3 Setting History Buffer Size The monitor collects data into a history buffer. History buffer makes it possible to have more data collected than fits on the screen. The data in the history buffer can be scrolled in the monitor display pane when the monitor is paused or stopped. When the history buffer fills, the oldest data is disregarded. You can change the history buffer size only when the monitor is cleared. Note that the history buffer size must be multiple of the interval. Trends DriveWindow 2 6-25 To change the history buffer size: ? If not yet selected, select the Monitor tab in the trend settings pane. ? Either double-click the History Buffer (s) field in the monitor settings pane, or select the History Buffer command in the Monitor menu or in the context menu of Monitor Settings. or A History Buffer (s) dialog box is presented with the present value shown in its edit field. Edit or enter a new (real) value and click OK. If you want to cancel the operation, click the Cancel button.
