Set Nominals
Nominals are calibration constants used in the process of converting raw analog data to
voltage values. The Set Nominals menu provides the ability to reset calibration
constants for all inputs, or for a specified set of inputs, to default values.
A user may decide to use this feature if, for example, temperature readings from the
SDS are deemed to be outside a certain acceptable range and subsequent calibrations
are not successful. When the calibration constants are reset, the device is placed in an
uncalibrated state and will require recalibration. If recalibration does not result in
temperature readings that are within an acceptable range, it is likely that the SDS has
experienced hardware damage and will need to be shipped to Super Systems Inc. for
repair.
The Set Nominals screen is shown in Figure 50
. To reset all nominals, simply select the
checkbox labeled “All” and then press the Set Nominals button.
