Grounding resistance measurement, ground voltage measurement, low
value resistance measurement
DC 9V zinc manganese dry battery R14S 1.5V 6 knots; can be
continuous standby 300 hours
Precision three-line measurement, simple two-wire measurement.
Way of measurement
Grounding resistance: rated current pole method, measuring current
3mA Max, 820Hz; ground voltage: the average rectifier.
Average, maximum, minimum
Line resistance check
To avoid the test line is not fully inserted into the instrument
interface or poor contact or the user to replace the extended test
line caused by the error,
make the grounding resistance measurement more accurate.
4 large LCD display, blue screen backlight, LCD size: 128mm × 75mm;
display area: 124mm × 67mm.
LED flashing indicator in the measurement, LCD countdown display.
Range: 0.01Ω ~ 2000Ω; Resolution: 0.01Ω; Accuracy: ± 1% rdg ± 3dgt.

Test line length
red: 20m, yellow: 10m, green: 5m
Simple test line
Auxiliary ground bar
2 root: φ10mm×150mm
Ground voltage: 3 times / sec; grounding resistance: 5 seconds /
The number of measurements
More than 5000 times (20Ω file measurement 10Ω, measured 1, stop 25
seconds and then test)
Measure the ground voltage: AC 600V below the measurement.
With RS232 interface, software monitoring, storage data can upload
the computer, save the print
Line RS232, 1.5m long
400 group, flashing FULL symbol indicates that the memory is full.
HOLD symbol display
READ symbol display
OL symbol display
When the measured value exceeds the alarm set value, the beep -
beep - beep alarm message
When the battery voltage drops to about 7.8V, the battery voltage
low symbol +- is displayed to remind the replacement battery
