Page 10: Battery Voltage Check
After powering on, if the LCD shows a low battery voltage symbol “ ”, it indicates that the battery is running low. Please charge it in time. The battery power is sufficient to ensure the accuracy of the measurement. When the battery power decreases, the power indicator bar decreases. -

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. - Page 12 spaced 5m ~ 20m, respectively, the S, H auxiliary grounding rod is buried deep into the ground in a straight line, connect the grounding test lines (black, green, yellow, and red) from the E, ES, S, and H interfaces of the meter to the ground electrode E under test, the auxiliary voltage electrode S, and the auxiliary current electrode H.

6．Three-wire Test Grounding Resistance Three-wire test: As shown below, short-circuit the ES, E interface of the instrument, which is a three-wire test, instrument operation is the same as four-wire test.The three-wire test cannot eliminate the influence of the wire resistance on the measurement, nor can it eliminate the influence of the change of the contact resistance between the instrument and the test wire and the influence of the change between the test wire and the auxiliary grounding rod. -
Page 15: 8．Soil Resistivity Test
The simple two-wire 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；... - Page 16 R——S-ES Resistance of soil between electrodes Four-pole method (Winner method)：Connect the test leads as shown below. Note the spacing between the auxiliary grounding bars and the depth of burial,bury H, S, ES, and E auxiliary ground rods in the ground in a straight line, connect the grounding test leads (red, yellow, green, and black) from the H, S, ES, and E connectors of the instrument to the H, S, ES, and E auxiliary grounding rods under test.

Page 19: Battery Instructions
VIII. Battery Instructions The instrument is powered by a 6V 4.5AH lead-acid battery. When the battery power is reduced, the power indicator bar is reduced. When the voltage drops to 5V, the battery symbol “ ” is displayed. Please charge in time. Low voltage affects the measurement accuracy. - Page 20 The contents of this user manual cannot be used as a reason to use the product for special purposes.
