teststand step fails when measurement is within diplayed limits

[Hoboken]

What property setting needs to be made to remedy this? Example: When the limits in a TestStand sequence step are set to two digits on the right side of the decimal point, the measurement value diplayed in the test report can be within the limits displayed on the test report and still fail the test. Say the limits are GE 0.00 and LE 10.00. If the measurement value is 10.001, it is displayed on the test report as 10.00 (which should mean it passes the test), but it fails the test.

Furthermore, if the teststand step uses LabVIEW, even setting the indicator (that feeds the teststand measurement) in the VI to two digits doesn't solve the problem. It still passes an actual value with that goes beyond the two digits to the right of the decimal point. So the VI indicator shows 10.00 and teststand report shows the measurement as 10.00, but the test still fails. All the property settings that I've seen only truncate or round the displayed value but not the actual value.

Question: Where is the property setting that truncates or rounds the actual value so a measurement of 10.001 rounded down to 10.00 will pass this test?

Thanks!

Hi,

What you are seeing in the report is how the result is formated, in the edit limits dialog you can format the limit values to n decimal places. by default its 6 places. Likewise you can also format the measurement value in the dialog for the measurement.

Just because the format is too 2 decimal places doesn't make the value a pass. If it 0.001 outside the limits it's still a failure. The result is be evaluated using the unformatted value.

Hope this helps

Thanks, Ray. I'm glad you confirmed that there is not a property for the LabVIEW indicator or a setting in the sequence step that would allow for rounding and truncating the actual measurement value (versus the displayed value). I thought I might be overlooking the obvious once again.
