instrument handle identifies a particular instrument calibration session.

You obtain this session handle from niDMM Initialize External Cal.

Function specifies the calibration mode used to acquire the measurement. For valid modes, refer to the NI 4065 6 1/2 Digit DMM Calibration Procedure, the NI 4070/4072 6 1/2 Digit FlexDMM Calibration Procedure, or the NI 4071 7 1/2 Digit FlexDMM Calibration Procedure.

Range specifies the range to calibrate.

For valid ranges, refer to the 4065 6 1/2 Digit DMM Calibration Procedure, the NI 4070/4072 6 1/2 Digit FlexDMM Calibration Procedure, or the NI 4071 7 1/2 Digit FlexDMM Calibration Procedure. Auto-ranging is not supported for calibration operations.

Input Resistance specifies the input resistance that the device uses. Input Resistance values are coerced up to the closest input resistance.

error in (no error) describes error conditions that occur before this VI runs. If an error occurred before this VI runs, the VI passes the error in value to error out. This VI runs normally only if no error occurs before this VI runs. If an error occurs while this VI runs, it continues and sets its own error status in error out. Use niDMM Error Message to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

	status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.
	code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning. The default is an empty string.

instrument handle out returns a handle that you use to identify the instrument in all subsequent instrument driver VI calls.

error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
