Safety Regulations
General
This measuring device is only to be installed and operated by qualified personnel
and according to the technical data in compliance with the safety precautions
and regulations set forth below. Additionally, the use of this equipment requires
compliance with all legal and safety regulations pertaining to each specific
application. Similar regulations apply to the use of accessories.
Operating electrical devices implies that parts of the device carry dangerous
voltages. Disregarding warning notices may lead to serious physical injury and
material damage.
It can be assumed that safe operation is no longer possible if the device
•
shows visible damage,
•
has been exposed to unfavourable conditions (e.g. storage beyond the
permissible climatic limits without adaptation to the ambient climate, dewing etc.)
or
•
has been exposed to major strain during transport (e.g. been dropped from
some height without visible external damage etc.).
No measurements must be performed on unprotected measuring circuits.
Qualified Personnel
Are persons familiar with the setting up, installation, starting of and operation of the
device and possess an appropriate qualification required for such activities.
Special warnings
•
Use of rubber gloves is a good safety practice even if the equipment is properly
operated and grounded.
•
Safety is the responsibility of the operator.
•
Use extreme caution when using the instrument around energized electrical
equipment.
•
Do not attempt to use the ground tester to twist or pry the ground electrode or
ground wire away from the equipment being grounded.
•
All metal objects or wires connected to the electrical system should be assumed
to be lethal until tested. Grounding systems are no exception.

Description of Instrument
The compliance with the actual EMC-regulations is documented by the attached CE-sign.
The clamp-on ground resistance tester enables the user to measure ground resistance of
the ground rod without the use of auxiliary ground rods. Clamp-on ground resistance
testers are used in multi-grounded systems without disconnecting the ground under test.
Applications:
•
earth resistance of various installations (high voltage pylons, buildings, cell phone
substations, RF transmitters etc.)
inspection of lightning protection systems
•

p
Snap (open and close) the jaws a few times to ensure the jaws mate properly.
Turn the power on, and set the rotary switch to the Ω position.
Do not clamp on to any conductor or open the jaws at this moment or
during self-calibration.
q At powering on, the clamp-on ground tester will self-calibrate for better accuracy.
Users should wait for the self-calibration to finish before making measurements.
During the self-calibration, the LCD will show CAL7, CAL6,..., CAL2, CAL1.
r

t
When the ground tester is ready, a beep sound will be heard.
Clamp on to the electrode or ground rod to be measured.
Read the value of Rg (ground loop resistance) from LCD.
Note: For better measurement:
Snap (open and close) the jaws a few times before powering on.
Do not clamp on to any conductor at the moment of powering on.
Note: If self-calibration does not stop:
This is because the self-calibration is not complete. The ground tester will
continue the process until a proper self-calibration is complete.
Check the jaw mating surfaces. If there is any dirt, dust, or any foreign
substance, clean the surface and power up again.
Note: Noise present in the electrode or ground rod:
If there exists over 3A current or 30V in ground rod, the symbol ”NOISE” will be
shown in LCD. Under the presence of noise, the reading is no longer accurate.
Note: If the jaw assembly is open during measurement, a symbol and the word
”OPEN” will be displayed on LCD.

position.
2. Press the FUNC button to select “HI“ or “LO” alarm. The current value of High or
Low alarm will be shown in the upper row of LCD.
3. Press the ▲ button or ▼ button to increment/decrement the value by 1 ohm. As
users hold the button longer, the speed of incrementing/decrementing will become
faster. The value can be increment from 0 ohm to 1510 ohm and then OL. Or the
value can be decrement from OL to 1510 ohm to o ohm. The value will roll over to
OL/0 if the current value is 0/OL.
4. Once the value is set, press the FUNC button several times until the upper row LCD
show no letters.
position. The unit will compare the current
5. When the rotary switch is set at the
value with the high and low values. If the current measurement is larger than HI
value, the unit will beep and show HI -- in the upper row of LCD. If the current
measurement is smaller than the LO value, the unit will beep and show LO – in the
upper row of LCD.

NOTE: If the HI value is set at OL, or the LO value is set at 0, the ALARM
function will not be performed. So they are method to disable one of the HI or
LO alarm.
NOTE: The HI value can’t be smaller than the low value. And the LO value can’t
be larger than the HI value. HI value will be adjusted to LO value plus 1 when
rollover occurs. The maximum value of LO value is HI value minus 1.
NOTE: If data logging is progressing, sound of beeping will be disabled to save
battery power. But the LCD still shows the warning letters of “HI—“ or “LO—“.
NOTE: The values for the high and low alarm are stored in the memory. They
are restored when the power is turned on.

Setting the Sampling Interval
1. Press the FUNC button until letters of “SEC” are shown in the upper row of LCD.
2. The unit shows the current sampling interval in seconds.
3. Press the ▲ or ▼ button to increment/decrement the value by 1 second. As users
hold the button longer, the speed of incrementing/decrementing will become faster.
The value can be incremented/decremented from 0 to 255 / 255 to 0 seconds.
Value will roll over when the value of maximum 255/minimum 0 seconds is reached.
4. Press the FUNC button several times until the upper row LCD show no letters.
6.3
Data Logging
The unit will start data logging if the REC button is pressed, and a symbol of REC will
be shown in LCD. Data will be recorded at the specified sampling interval.
Data logging will be stopped if the memory is full, or the unit detects the condition of low
battery, or the REC button is pressed again.
NOTE: If the sampling interval is set at 0 seconds, only one data is recorded. To
record next data, users can press the REC button again. The record number is
also displayed for about 1 seconds.

Read the Data Stored in Memory
1. Press the FUNC button until a symbol of “NO.” is shown in LCD. The
current record number is shown in the upper row of LCD. And the data is
shown in the lower row of LCD.
2. Press the ▲ or ▼ button to read the next/previous data,
3. If the users hold the ▲ or ▼ button longer, the record number will be
incremented/decremented faster. The record number will roll over when the
last/first record is reached.
6.5
Clear Data Memory
Press and hold the REC button, then turn the power on. Letters of “CL” will be shown to
indicate that memory is cleared.
6.6
Cancel the Auto Power Off
When the unit is turned on, a symbol of AP is displayed in LCD. That means the unit
will turn itself off in about 4 to 6 minutes. To cancel this function, user can hold the
FUNC button, then turn the power on. Symbol of AP will not be displayed in LCD.

Principle of Operation
7
Principle of Operation
The following diagram (fig. 1) shows a simplified typical grounded distribution system.
Its equivalent circuit (fig. 2) is shown below. If R1, R2, R3, ... Rn is combined as Req,
then only Rg and Req are left in the circuit (see figure). If a constant voltage is applied
to the circuit, the following equation is valid:
U
= Rg + Req
I
where
Req =
1
1
∑R
i
, i = 1,2,...n
If Rg and R1, R2, ... Rn are about the same, and n is a large number (such as 200),
then Req will be much less than Rg and maybe approach zero.
Rg >> ( Req → 0)
Example:
If Rg and R1, R2, ... Rn are all 10 Ω, respectively and n = 200, then Req by calculation
equals
Req =
1
1
1
1
+ + ... +
10
10 10
= 0,05Ω
In this example, we can see that as long as the number of multiple electrodes is large
enough, the equivalent resistance is negligible with respect to the ground resistance to
be measured.
