2.Technical Specification

Power Supply DC 9V (alkaline dry battery LR6 1.5V 6 sections)
Display Mode LCD Screen
LCD Size LCD display area: 58mm × 46mm
Backlight Controllable brightness, suitable for use in dim place
Measurement Precision three-wire measurement, simple two-wire measurement
Measuring Method Earth resistance: rated current pole-change method, measuring current 20mA Max;
Earth voltage: effective value acquisition
Current: effective value acquisition
Test Frequency 128Hz
Test Current >20mA(Sine wave)
Current Clamp Jaw Size Clamp Jaw 35mm×40mm
Auxiliary Pile Judgment Can avoid error caused by excessive earth resistance of the auxiliary grounding pole
Line Resistance Verification Avoid errors caused by the test line not being fully inserted into the tester interface or poor contact, as well as the errors caused by the user replacing or lengthening the test line,which makes the measurement of earth resistance more accurate.
Test Line 3 PCS: red 15m, yellow 10m, green 5m each 1 piece
Simple Test Line Red 1.5m
Auxiliary Ground Rod 2 PCS: φ9mm×230mm
Measurement Time Current: about 2 times/second;
Earth voltage: about 2 times/second;
Earth resistance: about 15 seconds/time
Measurement Times More than 5000 times (measure 10Ω in 20Ω gear, measure once, stop for 30 seconds and then test)
Line Voltage Measurement of earth voltage: measurement below AC 200V
Overflow Display Over-range overflow function:“OL”symbol display
Battery Voltage When the battery voltage drop to about 7.2V, the low battery voltage symbol flashes to remind to replace the battery.
Working Current Backlight: 56mA Max
Standby: 20mA Max (backlight off)
Measurement: 200mA Max (backlight off)
Tester Size 160mm×100mm×66mm
Weight Tester: about 470g (include battery)
Current clamp: about 190g
Total weight: about 2125g (include accessory)
Overload Protection Measuring earth resistance: AC 280V/3 seconds between E-P and E-C ports
