Occasionally, you will encounter tolerances that are not symmetrical (i.e. the upper and lower tolerances are not equal in magnitude from the target or nominal value). However, you can still calculate the TUR. For asymmetrical tolerances, calculate test uncertainty ratio using the formula given b...
it is then decided which types of compensation units (see this article) should be used. With regard to their locations, it should be kept in mind that the leads should be unburdened from reactive power at all time.
Define a color standard. Use color measurement instrumentation specific to your application needs. Measure the color you would like to match for the finished product and record its color values. Upload the standard’s color values to yourcolor formulation software. Calculate the recipe that best mat...
There's a fundamental difference between Cp and Cpk that takes into account the mean average. To calculate Cp, you need to know the specification limits and the standard deviation. It simply tells you whether or not the production process is capable of making products within the specifications. ...
To calculate dome volume: first, position the piston a measured distance into the cylinder, making sure the dome is below the deck. In this example, the piston is .150-inch in the hole. Calculate the exposed cylinder volume.Volume= (π) x (bore radius squared) x (exposed cylinder height...
When working with analog devices, many experts recommend to divide the resolution of the analog scale in half. This may work for many devices, but what if half the distance between scale markers exceeds specifications and tolerances? In this scenario, the half-digit resolution method fails to ad...
First you cover the bulk of the difference, minus some margin for the anticipated tolerances, aka "surprises". Once you are close, the uncertainties are MUCH smaller and you can easily cut exactly to be "spot on" after that: If you get the focus close but still short, you can push a...
Learn how to calculate your risk appetite. Evaluate and determine how to best tier your vendors - This is an important step that’s often overlooked. Tiering vendors based on the information they will have access to, the product/service they’re providing, or their regulatory/compliance ...
What is Signal to Noise Ratio and How to calculate it? The signal-to-noise ratio is the ratio between the desired information or the power of a signal and the undesired signal or the power of the background noise. Read Article Advanced PCB Design Techniques: OrCAD X Routing and Placement ...
How to Calculate Stepper Motor Steps Figure 2.Step Angle Calculation A step angle is the angle of rotation traveled in a single step. This can be calculated one of two ways—either by dividing the motor's full 360 degrees by the number of steps the motor takes to complete one revolution,...
