Safety Recommendations for Setting Up a Hipot Testing Workstation
Hipot testing is necessary for ensuring the electrical safety compliance of electronic equipment. However, testing the voltage on commercial equipment can result in errors and even death if the operators have not been properly trained on the importance of establishing a safe testing environment. Before any tests are performed, operators should be thoroughly trained on the effects of electrical currents on the human body, the importance of safety interlocks, and how to program the necessary tests and store them in memory. If operators lack the appropriate training, setting up a safe hipot testing workstation would be for naught. After prioritizing [...]
Whitepaper: How to Work Safely with High-Voltage Test & Measurement Equipment
How to Work Safely with High-Voltage Test & Measurement Equipment Vitrek’s advanced 4700 High Voltage Meter and SmartProbes offer alternative to legacy approach to calibrating high-voltage systems. INTRODUCTION When working with high-voltage test and measurement equipment, electrical and test engineers strive to achieve the most precise readings possible while also maintaining a safe work area. Typically, they employ external probes such as high-voltage dividers, but these instruments come with drawbacks and are prone to errors. This whitepaper describes an alternative approach to calibrating high-voltage systems. The advanced solution comprises Vitrek’s 4700 High Voltage Meter for direct [...]
WAFER MEASUREMENT – UNGROUNDED
Industry Semiconductor Applications Wafer Measurement – Ungrounded Measurement Type Metrology Description MTI Instruments Inc. has developed a thickness measurement device that eliminates the effect of varying target conductivity. Called the Push-Pull probe, it’s a unique version of the AccumeasureTM amplifier series. This special design provides accurate surface information for wafer bow and warp. Bow is the deviation of the center point of the median surface of a free, un-clamped wafer from the median surface to the reference plane. Where, the reference plane is defined by three corners of equilateral triangle. This [...]

High Precision Portable Signal Generators and Calibrators: Everything You Need to Know
High precision portable signal generators are portable electronic devices that generate highly precise signals for testing, system calibration, sensor simulation, troubleshooting, and monitoring. Unlike the benchtop signal generators that are used in laboratories, these hand-held portable devices are designed to be used in the field. The best high precision portable signal generators are also rugged and NIST traceable, meaning that their manufacturer calibrates them to standards from the National Institute of Standards and Technology (NIST). In terms of cost, high precision portable signal generators are more expensive than less precise, lower-end devices that can be held in the hand; [...]

MTI Application Note: How to Achieve <1um Accuracy When Measuring Roller Gap
How to Achieve <1um Accuracy When Measuring Roller Gap Roller Gap Measurement with MTI Digital Accumeasure Capacitive Probes Many roll-to-roll finishing processes typically use a calender, or series of hard pressure rollers, to deliver smooth, high-quality products of plastic, textile, or paper (Fig 1). Ensuring a consistent material thickness, however, depends on the ability to monitor, and maintain, a precise gap between rollers. This application note describes a quick and easy means for roller gap measurement. Problem How to measure the small gap between rollers to keep track of product thickness. Typically, it’s not possible to [...]
