according the measurement operation steps to testing.
5.2. Operation Steps
5.2.1. First of all, check whether the current line, voltage line and grounding network line used for
the test are open circuit situation or not (can be measured with multimeter), whether the rust on the
grounding pile is cleared, and whether the buried depth is appropriate (>0.5 meters). At the same
time, check whether the connection between the test line and grounding pile is conductive. If not,
please handle and reconnect it.
5.2.2. The length ratio of the current test line to the voltage test line is 1:0.618, and the length of the
current test line should be 3-5 times to the diagonal of the ground network.
5.2.3. The current test line and voltage test line shall be connected with the instrument at one end
according to the specified length, the other end is connected to the two grounding piles respectively
(as shown in Figure 2).
5.2.4. Check the test line that has been put in, connect one end of the multimeter to the current line
or voltage line, if no resistance value is displayed on the other end of the grounding network line,that
is open circuit , and the test should be carried out after confirmation.
5.2.5. After checking the wiring connection is correct, connect the instrument with AC220V/50HZ
power supply and electrify.
5.2.6. Press test button to start measurement.
5.2.7. After the instrument displays the testing is finish, record the test data.
5.2.8. After shutdown the instrument power, remove the wiring connection, and the test process is
finish.
5.3.
Instrument Operation Instructions
