JJF1001-1998 "common measurement terms and definitions" JJF1002-1998 "national verification procedures to write rules" GB 4793.1-2007 "measurement, control and laboratory use electrical equipment safety requirements" GB/T 13978-2008 "DMM" When using this procedure, it should pay attention to using the currently valid version of the documents cited.3 OverviewClamp resistance meter measuring earth resistance the basic principle is to measure the loop resistance, as shown in FIG. Part of the jaw clamp resistance meter By the coil voltage and current coils, the excitation signal voltage coils and sensing a potential in the circuit under test E. In the role of potential E generates a current in the circuit under test I. Clamp resistance meter to measure E and I, and by the following The formula to get the measured resistance R. R = E Forceps only the jaws of the clamp to stop the table vise measured grounding wire form a loop when the resistance measured, from the LCD screen can be Read grounding resistance without auxiliary electrode, without the grounding load isolation for online measurement. Figure 1 clamp resistance meter Grounding Resistance Measurement Fundamentals Figure 2 Schematic clamp resistance meter 1- LCD display; 2 - trigger; 3- clamp ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 1054-2009_English be delivered?Answer: Upon your order, we will start to translate JJG 1054-2009_English as soon as possible, and keep you informed of the progress.
