Page 12: Measuring Principle
guaranteed. VIII. Measuring Principle The basic principle of the ground resistance measurement of the clamp-type grounding resistance meter is to measure the loop resistance. See below. The jaw section of the clamp meter consists of a voltage coil and a current coil. The voltage coil provides the excitation signal and induces a potential V on the circuit under test. -

Boot, must maintain clamp meter natural resting state, don’t flip Clamp, don’t be imposed outside force on the jaw, otherwise can not guarantee the accuracy of measurement... -

measurement. 3. Resistance Test When the user thinks that the grounded value does not conform to the normal, you can use a random calibration ring to check whether the clamp meter is normal. The check ring has two resistances of 1Ω and 10Ω. After the power-on self test is completed, the large middle digit shows “OLΩ”... -

Although strictly on the theoretical grounding, because of the existence of so-called "mutual resistance”, R is not the usual parallel value in the sense of electrical engineering (slightly higher than its IEC parallel output value). But because a tower-grounding hemisphere was much smaller than the distance between the towers, and with a great number of locations after all, R is much smaller than R... - Page 19 .. .. .. ) 1 Where: R1、R2、……R are grounding resistances of N grounding bodies. 、R 、……R are the resistances measured with the Meter in the different grounding branches. It is nonlinear equations with N unknown numbers and N equations.

However, users need to pay attention to that: in response to the number of the grounding bodies mutually linked in your grounding system, it is necessary to measure the same number of the testing values for calculating of the program, not more or less. And the program would output the same number of grounding resistance values. - Page 21 As the resistance value measured by the Meter is the value of the series resistance from the testing line and two grounding resistances. Where: R is the resistance value measured with the Meter. is the resistance value of the testing line. Meter can measure out the resistance value by connecting the test lines with both ends.
- Page 22 Second, have R and R linked up, as shown in the following figure. Use the Meter to get the second reading R Third, have R and R linked up, as shown in the following figure. Use the Meter to get the third reading R In the above three steps, the reading measured in each step is the value of the two series grounding resistance.
