    Calibrator calibration interval standard

    Limited Knowledge here but experience from Air Force Metrology Lab. When I was in the AF, we used a paper system that monitored the calibration dates and results from each piece of equipment. As we calibrated things, (multimeters, scopes, gauge blocks, micrometers, etc) we would check the...

    inclined plate settler

    Ok.. Maybe I am off the mark here or missing something but here goes. Retention time for what? No matter the manufacturer of the clarifier, the amount of volume you will be able to send threw it will depend on what it is your trying settle out. If your asking about how long the flokulant...

    A bug in the electrical system. Noise?

    I am starting to think that I need to improve my technique when I attach shielded connections. But how? Here is what I have done. The servo drive and VFD drive output lines are both run with the same type of cable. The cable is 4 twisted 12ga wires with a spiral wound mesh type screen. Both...

    A bug in the electrical system. Noise?

    First, Thanks for all the helpful information. Both replies suggest that the hoist is generating power on its way down. I have limited experience on this so I could be wrong but wouldn't the load need to actually pull the hoist down in order to generate this feedback power? The lifting device...

    A bug in the electrical system. Noise?

    Ok.. I'm going to try to stick to just the quick dirty facts. I have 2 problems or maybe one? I have built a machine. A programmed hoist to be exact. (60 feet long) I have one small track section set up in my shop for the hoist carriage to ride back and forth on while I work out problems and...

    How to group objects?

    I tried the UNION command and it keeps telling me that "only coplaner or solids" can be selected. I can never get the block command to work right. There's something about drawing in 3D that autocad does not like. It does it, but things quickly become difficult to manipulate because the...

    Any way to save layer format?

    I am in the middle of a complex drawing and have a need to frequently visit the same "view" as far as what layers are turned on and off. My drawing has about 80 layers and about 50 of them are almost never needed to be turned on while I am drawing. Is there a way to flip flop between what...

    How to group objects?

    The only problem is that I have never used a lisp routine before. I know what they are but have never required one. I have much to learn with autocad. I think you would be surprised at how much I have done with this program and how little knowledge of its full usefullness I actually have.

    How to group objects?

    I've gotten good at making 3 dimensional drawings but am having difficulty when dealing with overlapping parts. How do I group a bunch of lines and circles into one object that will move as a group? And then be able to "un-group" them when needed? Im using AutoCad R14. Thanks,

    VFD and Servo in the same conduit?

    Can I get away with running the power cables of a VFD and a servo motor in the same metal conduit if both cables are shielded? The 2 motors are never operating at the same time but they are 50 feet away from the control box and only 24 inches from each other. The encoder cables are kept...
