Create acceleration measurement channel.

data type	parameter	describe
const char*	task	Task name.
const char*	chans	Channel list, Use commas to separate multiple channels or use colons to specify multiple channels in a row., such as "dev1/AIN1,dev1/AIN2,dev1/AIN3,dev1/AIN4", "dev1/AIN1:4", etc. Obtain Raw value: prefix RAW before AIN channel, for example: AIN1 returns Raw value "dev1/RAWAIN1"
const char*	reserved1	Reserved.
int32_t	terminalConfig	The input terminal configuration for the channel. 0: SingleEnded.
double	minVal	The minimum value, in units, that you expect to measure.
double	maxVal	The maximum value, in units, that you expect to measure.
int32_t	units	Output unit. 0: mV/g、mV/N. 1: m/s^2. 2: in/s^2. 4: V.
double	sensitivity	The sensitivity of the sensor Range： 0.000~10000.000mV/g、0.000~10000.000mV/N、 0.000~10000.000m/s^2、 0.000~10000.000in/s^2
int32_t	signalType	Sensor signal type. 0: IEPE.
const char*	reserved2	Reserved.

Note

Note that in IEPE mode, the explanation for the range setting is:

1. According to the set "maxVal" and "sensitivity", the internal will automatically set to the most suitable voltage range
2. Suggest setting 'minVal' as the minimum value of the sensor measurement range and 'maxVal' as the maximum value of the sensor measurement range
3. By setting the minimum and maximum expected measurements, the clipping effect can be achieved
4. According to the set "units", the collected data is the value of the corresponding unit

Note that when setting "units" to "V"：
1. The parameter 'sensitivity' is invalid, and the channel data returns the actual collected voltage value
2. Voltage range: ± 10V

Returns

On success, return value >= 0.

On failure, returns a negative error number.For detail, please Call VkDaqGetLastErrorInfo
