maximum time (5000 ms) Pass the maximum length of time in which to allow the read operation to complete. Express this value in milliseconds.
If the operation does not complete within this time interval, the VI returns the IVICOUNTER_ERROR_MAX_TIME_EXCEEDED (0xBFFA2003) error code. When this occurs, you can call IviCounter Abort to cancel the read operation and return the instrument to the Idle state. Defined Values: IVICOUNTER_VAL_MAX_TIME_INFINITE (-1) - Wait indefinitely for a timeout. IVICOUNTER_VAL_MAX_TIME_IMMEDIATE (0) - Do not wait for a timeout. Default Value: 5000 (ms)
