II.Introduction
Intelligent lightning protection component tester, also known as lightning protection
component tester, SPD field tester. It’s a Special instrument for performance
testing of lightning arresters, lightning arresters, surge protectors, varistors, cermet
discharge tubes, and direct-air lightning arresters.The instrument adopts the
charging function and is used offline to overcome the shortcomings of the traditional
product to be plugged in and used inconvenient on-site operation, the voltage output
2000V application range is more extensive, the use of high voltage
short circuit protection, automatic discharge function, the instrument is reliable,
safe and durable. At the same time, it adopts luxurious large-color screen display,
data storage, data review, qualified judgment, automatic shutdown, USB data upload
and other functions. The machine is beautiful and high-grade, wide in range, high in
resolution, convenient in operation, convenient to carry, accurate, reliable, stable in
performance and strong in anti-interference ability.
Moreover, it has anti-vibration, dust-proof and moisture-proof structure and adapts to
the harsh working environment. It is an indispensable instrument for meteorological
lightning protection, electric power, post and telecommunications,
communication, electromechanical installation and maintenance, and industrial
enterprises that use electricity as industrial power or energy. It is suitable for
measuring performance parameters of various arresters and surge protectors.
The intelligent lightning protection component tester consists of medium and large
scale integrated circuits. The output power of this instrument is large, the initial
operating voltage measurement range is 10-2000V, the leakage current
measurement range is 0. 1~199.9uA, the repeatability is good, and the one-button
measurement is convenient and quick.

VI.Operation Method
1．Power On/Off
Press the "Power On/Off" button in the power-off state to turn it on. Press the "Power
On/Off" button in the power-on state to turn it off.
2．Battery Voltage Check
After the power is turned on, if the LCD displays the battery voltage
low symbol “ ”, it indicates that the battery is low, please replace the
battery in time. The battery power is sufficient to ensure the accuracy of
the measurement.
3．Varistor Test
When measuring, press the “Type Select” button to select “varistor” and clamp the
varistor under test (as shown below). There are two modes to choose from under the
“varistor” type, namely “automatic mode” and “manual mode”, which can be selected by
pressing the “mode selection” button.
Under the "automatic mode" test, you only need to press the "start test" button to start
the test. During the test, the word "in progress..." will be displayed in the lower right corner.
When the test is completed, the message "Test completed!" is displayed. . If you want to
interrupt the test process during the test, you can press the "Exit" button to
interrupt the test.

Under the “Manual Mode” test, press the “Voltage Setting” button and press the “ ”
or “ ” button on the direction button to adjust the value of “Limit Voltage” to be more
than 1.2 times the nominal value of the measured varistor. Press the(“ ” ,“ ”)
button to add or subtract 1 for short press, plus or minus 50 for long press, then press the
"OK" button, then press the "Start Test" button to start the test.The voltage value when the
current shows about 1 mA (1000 uA) is the U1mA value (breakdown voltage),at this point,
you can press the “Start Test” button again to check the leakage current value of the
varistor under test.If you want to end the test, you can press the “Exit” button or press the
“Start Test” button when checking the varistor leakage current value.
4．Discharge Tube Test
When measuring, press the “Type Select” button to select the test type as “Discharge
Tube” and clamp the measured discharge tube (as shown).Press the “Start Test” button to
start the test. At this point, you can see that the voltage value is rising. When the voltage
value stops, the test is completed. At this time, the voltage is the ignition voltage of the
tested discharge tube (DC breakdown voltage).
