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. -

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；... -
