The program (software) has a resistor menu where the values and uncertainties of up to 40 resistors can be entered by the user and stored by the program.The number 40 corresponds to the number of the available channels of 2 scanners that can be connected to the bridge and chosen automatically by the running program in any possible way to use one resistor as Rx and any other one as Rs. If required, the running measurement program can update the resistor menu by changing the value and uncertainty of the actual Rx in accordance to measurement results. webmaster@amtest.ro (AM-TEST TM ELTH ROMANIA) Fri, 08 Dec 2006 00:00:00 +0200 http://www.amtest.ro/articles/2/1/Applications-for-Precision-Impedance-Meters-in-a-Standards-Laboratory/Required-Capabilities-for-Precision-Measurements.html Introduction The QuadTech 1689 Precision RLC Digibridge™, which measures resistance, capacitance and inductance, has found wide acceptance in production and incoming inspection applications because of its high measurement speed and accuracy. Its impedance and frequency ranges have also made it an important tool for component engineering and quality control measurements. The 1689 also has been found to be a valuable instrument in many Standards Laboratories, where it has assumed tasks that used to require manually-balanced bridges and special test setups. In addition, it provides some new measurement capability not previously available. This application note discusses some of these applications and techniques. webmaster@amtest.ro (AM-TEST TM ELTH ROMANIA) Wed, 06 Dec 2006 00:00:00 +0200
