Page 12: Ⅷ. Measuring Principle
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. -
Page 13: Battery Voltage Check
Before booting up, the trigger should be pressed for a couple of times to ensure the jaws are well closed. 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 Press the power button to switch on and off. -
Page 14: Resistance Test
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”... -

In the data review state, long press the "SET" button, then press the "POWER" button to delete the stored data Ⅹ. Battery Instructions When the voltage drops to 5.2V, the battery symbol " " is displayed. Please replace the battery. Low battery voltage affects measurement accuracy. - Page 18 Where: R is the target grounding resistance. is the equivalent resistance of the other entire tower grounding resistances paralleled. 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).
- Page 19 the grounding resistance paralleled is calculated by the usual sense. Thus, for the grounding system of N (N is smaller, but larger than 2) grounding bodies, it can offer N equations: .. .....
- Page 20 solutions. In principle, in addition to ignoring the mutual resistance, this method does not have the measurement error caused by neglecting R 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.
- 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.
