i have a VSMR15 and the spec tube light has been on for about a month and it is the color blue, any idea is to what is going on with it?
This is a vacuum systems product and is not covered in this discussion. I will forward your question to that group.
Here is an answer I received directly from the vacuum division:
The “spec tube” error is because the system has not achieved a propervacuum. It could be because the roughing pump is not running, or the test portthermocouple is bad.
In the U.S., you can contact the Vacuum Division directly 800 882-7426, option 3
I agree with the answer from Mitch.
