I. Attention

Thank you for purchasing this ground tester from our company. In

order to make better use of the product, please be certain:

----To read this user manual carefully.

----To comply with the operating cautions presented in

this manual.

1 Under any circumstances, use the Meter should pay special

attention to safety.

2 Pay attention to the measurement range of the Meter and the

using environment provided.

3 Pay attention to the text labeled on the panel and back plane

of the Meter.

4 Before booting up, the trigger should be pressed for 1-2 times

to ensure the jaws are well closed.

5 At Boot time, DO NOT press the trigger, nor clamp any wire.

6 Before the auto inspection is completed and the "OL Ω"

symbols are showed, the measured objects cannot be

clamped on.

7 The jaw planes contact must be maintained clean, and should

not be polished with corrosive and rough materials.

8 Avoid any impact onto this Meter, especially the Jaw contact

surface.

9 This Meter will have some buzzing sound in measurement

process, and it is normal.

10 The measurement current of the wire should not exceed the

upper limit of the Meter.

11 Please take out the batteries in the case of the Meter being

idle for a long time.

12 The dismantling, calibration and maintenance the Meter shall

be operated by the authorized staff.

13 If the continuing use of it would be dangerous, the Meter

should be stopped using immediately, and immediately sealed

for the treatment by the authorized agencies.

II. Brief Introduction

Its performance is mainly reflected in:

Breakthrough in self-test the boot a long time to wait, start

immediately into the test.

Breakthrough relay self-test mode, using the most

advanced processing algorithms and digital integration

technology, a fully intelligent.

Break the old product to heavy issues, more in line with

characteristics of handheld devices.

New design, panel operation with 6 buttons, better

performance.

An increase of sound and light alarm, "beep—beep--beep

--" alarm sound.

Increase the interference signal recognition indicator.

Improved anti-jamming capability and test stability.

Stored data: 99 Units.

Wider range: 0.01Ω-1200Ω

Lower power consumption: Maximum operating current

not exceeding 50mA.

The ground tester is widely used in the grounding resistance

measurement of the power, telecommunications, meteorology,

oilfield, construction and the industrial and electrical equipment. In

the measurement of a grounding system with loop current, does

not require breaking down the grounding wire, and need no

auxiliary electrode. It is safe, fast and simple in use.

The ground tester can measure out the faults beyond the

reach of the traditional methods, and can be applied in the

occasions not in the range of the traditional methods.

The ground tester can measure the integrated value of the

grounding body resistance and the grounding lead resistance.
