- Font: Three font varieties are available. Monospace takes less space, sans-serif improves legibility and serif is easiest to read. Two additional formats are available, bold and italic.
- Unit name placement: The units string is shown in the caption banner by default. Select "Show unit name below data value" to have it shown below the data in a larger font.
- Decimals: Select the number of decimal places to show or select scientific notation for extremely large or small 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.
- Warnings and alarms: When the display is created, the values for these fields are based on the values specified in the grid interface / single channel editor for the selected channel. See System channels > Scaling parameters > Warning and Alarm min and max for more information. However, these initial values can be changed in the single channel digital meter.
