Overflow Display：Exceeding measuring range overflow function: "OL" symbol display
Circuit Voltage：Measuring earth voltage : AC 600V MAX
Auxiliary Earth Rod：2 PCS: Φ10mm×150mm
Testing Wires：Five wires: each for Red 20m, yellow 10m, green 5m, red 1.6m, green 1.6m
Interface：USB interface,software supervision, storage data can be uploaded to computer, saved and printed;data transmission line length:1.5m
Wire Resistance Verification：Avoid errors caused by the test line not fully inserted into the instrument interface or poor contact or the user replaces the lengthened test line, ensure grounding resistance measurement more accurate
Alarm Function：Measuring value exceeds alarm setting value, will "Toot-toot-toot" alarm hint
Auto Power-off：10 Minutes after power on, will outage and automatic power off
Battery Voltage：While battery voltage decreases to around 7.8V, will display battery voltage low symbol, and reminding to replace the battery
Overload Protection：Earth resistance: between each interfaces of E-P,E-C, AC
