Page 3: I．safety Precautions And Procedures
I．Safety Precautions and Procedures Thank you for purchasing our company's digital grounding resistance tester. Before using the instrument for the first time, in order to avoid possible electric shock or personal injury, please be sure to read and strictly observe the safety rules and precautions listed in this manual. In any case, the use of this instrument should pay special attention to safety. -

3．The working error (B) is the error within the rated operating conditions, which is calculated from the inherent error (A) and variation error (Ei) of the existing instrument.。 A： inherent error E1：Changes due to location changes E2：Changes due to power supply voltage changes E3：Changes due to temperature changes E4：Changes due to disturbance voltage variations E5：Changes due to contact electrode resistance... -
Page 9: 4．Wire Resistance Check
If the plug is not fully inserted or contacted, the measurement value may be incorrect. This instrument can not be used for commercial power supply voltage measurement, special circumstances need to measure, only can use the S and E interfaces connect to measure, the commercial power supply voltage cannot be measured when the H and S interfaces are shorted. -

instrument interface or poor contact; to avoid the error caused by the user to replace or lengthen the test line, the line resistance check function is specially designed to measure the low-value resistance more accurately. After connecting the test line and the meter, short the other end of all the test lines. -

yellow, and green) from the H, S, and E ports of the meter to the auxiliary current electrode H, auxiliary voltage electrode S, and ground electrode E under test. As shown: 6．Simple Method for Measuring Ground Resistance When using the commercial power system grounding as an auxiliary grounding pole to measure, it must be confirmed by the checker that it is the grounding pole of a commercial power system. -
Page 12: 7．Backlight Control
The simple method measures the grounding resistance. The instrument reading value is the sum of the grounding resistance of the measured grounding body and the grounding resistance of the commercial grounding body. That is： RE=RX＋re And： RE is the meter reading value； RX is the grounding resistance value of the grounding body under test；... -
