IviDmm_IsOverRange
IviDmmBase Capability Group
C Function Prototype
ViStatus IviDmm_IsOverRange (ViSession vi, ViReal64 measurementValue, ViBoolean *isOverRange);
Purpose
This function takes a measurement value that you obtain from one of the Read or Fetch functions and determines if the value is a valid measurement value or a value indicating that an overrange condition occurred.
If an overrange condition occurs, the measurement value contains an IEEE defined NaN (Not a Number) value indicating that an overrange occurred.
Parameters
| Inputs | Type | Description | ||
| vi | ViSession | The instrument handle that you obtain from the IviDmm_init or IviDmm_InitWithOptions functions. The handle identifies a particular IVI session. | ||
| measurementValue | ViReal64 | Pass the measurement value that you obtain from one of the Read or Fetch functions. The driver tests this value to determine if the value is a valid measurement value or a value indicating that an overrange condition occurred.
|

| Outputs | Type | Description | ||
| isOverRange | ViBoolean | Returns whether the measured value is a valid measurement or a value indicating that an overrange condition occurred.
Valid Return Values: VI_TRUE (1)—The value indicates an overrange condition occurred. VI_FALSE (0)—The value is a valid measurement. |
