Welcome to part 4 of the STa6000 tutorial series.
In this video we will be calibrating the tool we used in part 3 to demonstrate verifying torque.
If you haven't seen part 3 yet I recommend watching it before this video.
First we will start by taking our Atlas Copco programming cable
and connecting it to the USB serial adapter.
Next we connect the opposite end to the RS232 #2 port that is above the ethernet port.
Then close up the controller.
Then using the STa6000 USB cable we connect the adapter directly to our analyzer.
We now attach our rotary transducer to our analyzer, then mount the transducer to our tool.
Back in ToolsTalk PF we now must check that our batch count is at least 3 in the Pset we created in part 3.
Here we will demonstrate what happens when you don't have a batch count of 3 or more set.
We enter the calibration menu
Select Power Focus
And then serial since we are connecting through our adapter.
Next we see our tolerance of +/- 5%
and we attempt to start the calibration.
Once the analyzer establishes communication we get a message saying the batch size is wrong.
To remedy this we must change our batch count in ToolsTalk PF or on directly on the controller if you have a graph model.
The calibration needs a min. of 3 results to be able to calculate a proper calibration value.
We change ours to 3 for a quick calibration, then click store to save our Pset.
We switch right back over to our analyzer and click start again.
But this time we are successful in loading our Pset and starting the calibration.
The top value now displays the results from our transducer.
While the lower value displays the results directly from our Power Focus controller.
We will now start our rundowns.
After our first rundown we see the controller is displaying a value of 0.9 Nm
While our transducer measured .914
The batch count shows we have performed 1 readings out of 3.
Our second batch values now display as we complete our second rundown.
After our 3rd and final rundown we are prompted that our batch is complete.
As you can see our controller and transducer values are very close together.
Well within our 5% tolerance.
This tool doesn't need its calibration value changed, but we will do it anyway.
By hitting the top left button we now see our old calibration value and what the analyzer suggests we update it to.
Our old value was 6.0 but our new suggested value is 6.115
By clicking store we will now update our calibration value which is saved directly to the tool.
Now no matter what controller we use, this tool will remember its calibration value.
Let's run the calibration one more time.
Again we hit start to repeat the process.
The analyzer will automatically use the same Pset as before.
If you wish to change the Pset you must select it before you start the test.
We will now perform another 3 rundowns.
Right away you can see our readings are even closer to each other than before.
After the batch is complete we can now see what the analyzer recommends for our new calibration value.
They are so close that they don't need to update it,
but we do anyway.
Back at the main menu on the analyzer we can go into the reports menu
then calibration to see the 2 calibrations we just performed.
We can print these directly from the analyzer if its networked, delete the test or open the report to view it.
Here we see our old and new calibration values, and it says that we have updated the value.
If we hit cancel after our calibration the value would not have updated, but the report would still have saved.
Under the MAX tab we can see the difference was only 2.08%
well within our 5% limit, meaning the tool has passed.
If you'd like to save and print your results from a computer you can connect to a PC running ToolsTalk BLM via USB.
Once connected open up the reports tab.
Then click calibrations, then click Power Focus calibration report.
On the left we have both reports listed.
All of the data shown on the analyzer is now formatted nicely on the page to read.
From here we can save our results on the hard drive as an excel doc, PDF or word doc.
This concludes part 4 our of STa6000 tutorial series.
