Min/Max tracking of multi-channel digital meter with alarms

A Min/Max chart is a digital display of minimum, current and maximum data values for each channel. The minimum and maximum values are continuously tracked from the start of the test run until they are reset by the user, or the browser is refreshed or closed. Warning and alarm level exceedance indicators are provided on a per channel basis.

Specify Range min, Range max, alarms and warnings in Test Configuration in the Scaling mode section of the Edit channels dialog or the grid interface.

See also User preferences, General menu item for Decimal point handling of Range min/max values.

There are several options available from the menu. Click the options menu button:

  • Freeze: Select to pause the data display. Deselect to resume live data.
  • Reset: This resets the minimum and maximum values.
  • Update rate: Select the rate at which the display refreshes at 1, 2, 5 or 10 times per second. Note that in cases where the channel sample rate is less than the selected update rate, the display refreshes at the lower sample rate.
