INT32S DRV_AIScale ( PTR_T DeviceHandle, PT_AIScale * lpAIScale );
Converts the binary raw data, which is usually retrieved from the DRV_AIBinaryIn, into its corresponding voltage or any other desired analog value.
Some parameters, such as maximum analog input value (MaxVolt), digital count range (MaxCount), zero point offset (offset), input digital value (reading) and return analog value (voltage), are stored in the PT_AIScale structure pointed by the lpAIScale.
| Name | Direction | Range | Description |
| DeviceHandle | input | default | The pointer retrieved from the DRV_DeviceOpen which specifies the target device. |
| lpAIScale | input / output | default | The pointer to indicate the structure PT_AIScale that stores maximum analog input value (FP32 MaxVolt), digital count range (INT16U MaxCount), etc. |
| 1. 0 | Successful. |
| 2. other value | Please reference ErrorCodes |
