The JEM-EUSO telescope will be, after calibration, a very accurate instrument which yields the number of received photons from the number of measured photo-electrons. The project is in phase A (demonstration of the concept) including already operating prototype instruments, i.e. many parts of the instrument have been constructed and tested. Calibration is a crucial part of the instrument and its use...
Low Frequency (LF) voltage and current are important parameters in Electrical Metrology. The standards for LF voltage and current are established by assigning AC-DC transfer difference to thermal devices i.e. thermal converter (TC) or thermal transfer standard (TTS) alongwith current shunts. Automated calibration systems have been developed using Null and Budovsky's techniques for calibration of precision...
National Physical Laboratory India (NPLI) is the premier research & development center and the National Metrology Institute, which provides traceability in measurements by calibration throughout the country. Low Frequency voltage and current are very important quantities in electrical metrology. The standards for LF voltage and current are established by assigning AC-DC transfer difference to...
National physical laboratory (NPL) of India is the premier research & development center and the National Metrology Institute, which provides traceability in measurements by calibration throughout the country. Radio Frequency (RF) power is one of the most important quantities in RF metrology. The measurement of calibration factor for thermistor mounts by direct comparison technique in the frequency...
