  • Clamp-On Ground Resistance Testing. Step-by-Step Usage
    The clamp-on ground resistance testing technique offers the ability to measure the resistance without disconnecting the ground. This type of measurement also offers the advantage of including the bonding to ground and the overall grounding connection resistances.
  • A Method of Determining the Elastic Properties of Alloys in Selected Crystallographic Directions For X-Ray Diffraction Residual Stress Measurement (.pdf)
    A technique and apparatus are described for obtaining. the elastic constant E/(1 + ?) in selected. crystallographic directions for the purpose of. calibrating x-ray diffraction residual stress. measurement methods. The preparation of a simple. rectangular beam specimen with two active electrical
  • Implementing Ohmmeter/Temperature Sensor
    This application note describes a method forimplementing an ohmmeter or resistance type temperature sensor using the PIC16C5X series of microcontrollers. The ohmmeter requires only two external components and is software and hardware configurable for resistance measurement with resolutions from
  • Sensor Sense: Hall-effect current sensors
    The best place to measure current consumption is in the main power feed. The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if the current being measured
  • Precision RTD Instrumentation for Temperature Sensing
    Analog-to- EQUATION 1: RTD RESISTANCE Digital converter, and two resistors to measure RTD ?? Code resistance ratiometrically. A ±0.1°C accuracy and ----------------------------------R R= ?? RTD A n1- ±0.01°C measurement resolution can be achieved ?? 2 - Code across the RTD temperature range of -200°C
