Description

 

age1439_meas_start provides an easy way to initiate a measurement in a single module system.

 

This command waits for a valid hardware setup, then, if the instrument is in a valid state, performs

 

the equivalent of age1439_meas_init.

 

Parameters

id

is the VXI instrument session pointer returned by the age1439_init function.

 

Comments

 

See “The measurement loop” in chapter 3 for details on how a measurement progresses through

 

the four states.

 

This function performs the following sequence:

 

1.

Waits for AGE1439_STATUS_HARDWARE_SET bit to be set.

 

2.

Returns AGE1439_START_ERROR if more than three seconds elapses in step 1.

 

3.

Returns AGE1439_SETUP_ERROR if AGE1439_STATUS_SETUP_ERROR was

 

 

detected in step 1.

 

4.

Performs age1439_meas_init and returns AGE1439_SUCCESS.

Example

The program acvolts.exe described in the initiate a very simple measurement using

example programs provides an example of how to age1439_meas_start.

Return Value

Values other than AGE1439_SUCCESS indicate an error condition or other important status condition. To determine the error message, pass the return value to “age1439_error_message” on page 102.
