GENERAL INFORMATION
The "LR Tester" is a portable electronic analyser designed to the full test of the status of the Early Streamer
Emission (ESE) circuit, performing tests on the discharge circuit and on the impulse amplifier of ESE
lightning rods made by Cirprotec.
The LR Tester is a portable device which incorporates the last electronic generation, and performs the test
of ESE lightning rods by an automatic manner. After connecting the Tester to the Lightning Rod, only must
push the activation buttons (element nº 4 of the Diagram 1). The Tester starts then the cycle of tests
composed by three phases necessaries for:
1. testing the charge circuit of ESE system.
2. testing the discharge circuit of ESE system.
3. testing the integrity of impulse amplifier.
Ones completed these steps, the cycle of test is over and the Tester gives as the result PASS in the case
when the device response was correct, and err when some of the obtained values were not correct.
The LR Tester is an equipment designed both to guaranty the integrity of the radius cover of the lightning
rods after repetitive impacts and to be an useful instrument for the installation of lightning rods allowing to
check the correct installation and connexion of the lightning rod with the cable to the earth terminal.
WORKING PRINCIPLES
The built-in Early Streamer Emission (ESE) circuits allow to enlarge the protection radius which would be
supplied by a classical Franklin lightning rod with the same dimensions. Therefore, the actual coverage
level depends both on the ESE circuit and the size of the lightning rod. As the dimensions are considered to
be inalterable during the time, the LR Tester can analyse the integrity of the lightning rod measuring only the
ESE system.
The LR Tester is designed to perform appropriate measures on the ESE circuit, to check the operation of
various blocks of ESE system and display an acceptance or error value. Logically, the LR Tester
guarantees only the integrity of ESE system and its correct connexion to the earth termination, but not the
physical integrity of the lightning rod, so an acceptance result in a lightning rod with physical damages, like
divided or doubled lightning rod does not signify that the lightning rod will maintain the covering radius,
because this one does not depends only on ESE system, but also on the physical parameters, in order to
guaranty the covering radius, therefore a visual inspection of the physical integrity should be necessary.
The LR Tester verifies the correct connection of the lightning rod with the earthing wire, but it does not verify
the earthing system installation on the whole, which should be tested its own with an appropriate tester.

INSTRUCTIONS OF OPERATION
See table 1 for an enumeration of the steps to follow.
The test must be carried out with the analyser connected to the lightning rod. When the Tester is used to
check an installation, it is necessary to connect one or two poles (any of both) to the rod and the other to the
earthing terminal point in order to check the proper connection between both components of the system.
It is also important to check the fixing bolds of the earthing wire and those of the ESE sheltering carcass are
properly clamped. If not, it would lead to a bad test measurement.
To start the test cycle,both thumb switches must be pushed simultaneously,using both hands.Keep pushing
those thumb switches during the whole verification cycle, until the end of the test. If during the test process
incidentally the buttons are left unpressed,please,re-start the whole test cycle again after leaving a
prudential 5 seconds time interval(in order to discharge the device)before pushing both thumb switches
again.
The test for installed lightning rods should not be carried out under stormy weather conditions since the
Early Streamer Emission device might have acquired some charge beforehand which would interfere the

measurement. Besides, there is a real risk of lightning strike. If an ESE device test has to be carried out
under environments with high electrostatic charge levels, the ESE device has to be removed from the
installation and verified in a safe place without external charge presence.
During the verification test cycle neither the lightning rod and ESE device set nor any other part of the
installation must be touched since the LR Tester creates voltages up to 2000V which might originate
electrical discharges which in turn might be dangerous.
Table 1: Verification steps
1. Plug the cables supplied with the LR Tester to the output
terminals of the analyser.
2. Connect the clamps to the opposite extremes of each
cable.
3. Connect the clamps to the lightning rod in the test
position, as shown in figure 2.
4. Push both buttons simultaneously in order to start the
verification cycle.
5. Wait a few seconds while the device performs the
measurements.
6. Read the display indication with the result of the TEST.

Unscrew the bolt and remove the back carcass-lid.
The rubbish bin with a line through it means that in the
European Union, the product must undergo selective
disposal for the recycling of electric and electronic
material, in compliance with Directive WEEE
2002/96/CE.
Table 2: Messages on the display
TST1: The analyser is performing the measures and
calculation on the ESE device .
TST2: The analyser is performing the measures on the
impulse amplifier device.
TST3: The analyser is performing the measures and
calculations on the discharge device.
PASS: The ESE device of the lightning rod is operative
and correctly connected.
Err:
Erroneous measurement. Check the low-battery
indicator. If it's lighted, replace the battery with a
new one (see diagrams 1 and 3).
In the contrary case, check the connections of the
installation and repeat the checking cycle; if the
message still appears on the display, remove the
lightning rod and perform the test again with the
rod standing alone. If the message still persists, a
substitution of the lightning rod is required.
