II. Brief Introduction
Clamp on ground resistance tester is a major breakthrough in traditionalTR-5300
grounding resistance measurement. It is widely used in the grounding resistance
measurement of the power, telecommunications, meteorology, oilfield, construction
and the industrial and electrical equipment.
Clamp on ground resistance tester , in the measurement of a groundingTR-5300
system with loop, does not require breaking down the grounding wire, and need no
auxiliary electrode. It is safe, fast and simple.
Clamp on ground resistance tester is equipped with a long jaw sized 55mmXTR-5300
32mm, particularly suitable for the grounding with the flat steel.

2. Description of Special Symbols
(1) Symbol of an open jaw: shows as a jaw is in open state. In this case, trigger may
be artificially pressed, or the jaws have been seriously polluted, and not available for
measurement.
(2) Symbol of low battery voltage: shows when the battery voltage is lower than
5.3V. In this case, accuracy of the measurements cannot be guaranteed unless batteries
are replaced.
(3)" " symbol indicates that the measured resistance exceeds the upper limit ofOL Ω
the meter.
(4) "L0.01 " symbol indicates that the measured resistance exceeds the lower limit ofΩ
the meter.
(5) MEM symbol of storing data records
(6) MR symbol of reviewing data records: shows when reviewing data records stored,
as well as number of record.
(7) NOISE symbol of noise signal: shows when there is noise current in earth resistance
to measure. In this case, accuracy of measurement cannot be guaranteed.

VI. Operate the meter
1. Boot Up
Before to boot up, press trigger for few times to ensure the jaws are well closed.
Press power to boot up the meter. Firstly, self in pection is performed. It is ready for
resistance measurement when 'OL' shown on screen after self inspection.
6

During self inspection, DO NOT press the trigger, nor open the jaw, nor clamp any wire.
During self inspection process, make sure to keep the meter free. Do not overturn the
meter, nor impose any external force on jaw. Otherwise, accuracy of measurement
cannot be guaranteed. If jaws clamped around a conductor loop during self
inspection, any following measurement will be inaccurate. In this case, please remove
conductor loop and reboot.
2. Shutdown
When the meter is power on, press POWER key to shut it down. After five minutes the
meter started up, LCD screen start flashing, In order to save battery life, the meterwill
automatically shut down after the flashing state is sustained for 30 seconds. To press
POWER key when flashing, the meter resume status of working. In HOLD state, it is
required to firstly press HOLD key to quit from HOLD state, then press POWER key to
shut it down.
3. Resistance Measurement
After booting self inspection it shows, is completed 'OL ’ ready to proceed withW
resistance measurement. At this point, press trigger to open jaw, clamp the loop to
measure, read out resistance value. If necessary, self calibration can be done with
verification resistor in standard accessory as shown in the following figure.
The reading should be consistent with the normal value
on verification resistor ٥ .Carlibrated value of٫١W
verification resistor is in condition of temperature
of 20 . It is normalto find a difference of numerical℃
1 word between the shown value and nominal value
For instance: If nominal value of verification
resistor ٥ , ٥ or 5.2 is normal٫١is ٫٠showingWWW
and accepted. Showing 'OL ’ indicates that the measured resistance value exceededW
the upper limit of this meter. Showing '٠ ’ indicates that the measured٫٠١LW
resistance value exceeded the lower limit of this meter.
4. Data Hold/Release/Store
7

In resistance measurment mode, press HOLD button to lock displayed value with
symbol HOLD showing, as figure 1 shown below.
Press HOLD button again to unlock.
In measurment mode, press MEM/READ to enter data storage mode with symbol MEM
showing on screen. The displayed reading is stored and numbered with number shown
on top right of screen.
Press POWER button again to quit storage mode and revert back to measurment
mode.
To repeat above operation can stored up to 99 pieces of data points.
To quit storage mode, press MEM/READ button.
All stored datas will not removed after rebooting the meter.
Figure 1
Figure 1, save the measured 0.016ohms as No. 01 data record.
Figure 2
All stored datas are in memory and won’t drop when shutdown.
5. Review stroed data
Figure 3
When the meter is under measuring, long press (more than 3 seconds) MEM/READ
button to enter data review mode, with MR symbol shown , as fig. 3 shown above. The
No. 1 stored data is shown by default. Press MEM/READ button to review every pieces
8

To quit data review mode, long press MEM/READ button.
Press HOLD button to scroll up the recalling data.
6. Configure alarm value
In resistance measurement mode, long press HOLD button to enter configuration
mode for alarm value, as figure 4 below . The first digit to configure is the top digit.
Press button MEM/READ to switch digit from the high to low. When configuration
finishes, long press MEM/READ to return to measurement mode.

8. Delete Data
Firstly long press button MEM/READ to enter review mode of stored data. Short press
POWER button to delete the last record in memory. Long press POWER button to enter
CLR screen, then press POWER button again to delete all data or press MEM/READ to
cancel deletion.
