Operation method of SXFL-2GB lightning protection element tester

Operation method of SXFL-2GB lightning protection element tester

1. Switch on / off

In the off state, press the "on / off" button to turn on the machine, and in the on state, press the "on / off" button to turn off the machine.

2. Battery voltage check

After booting, if the LCD displays a low battery voltage symbol "", indicating that the battery power is insufficient, please replace the battery in time. Only with sufficient battery power can the accuracy of measurement be guaranteed.

3. Varistor test

During measurement, press the "Type Selection" key to select "Varistor" and clamp the varistor under test (as shown in the figure below). There are two modes to choose from in 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. The SXFL-2GB lightning protection element tester will display the word "testing ..." in the lower right corner during the test. 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 then press the "" or "" button to adjust the "Limited Voltage" value to reach more than 1.2 times the nominal value of the varistor under test (upper "" 、 Press “”) key to add or subtract 1 when short press, and increase or decrease by 50 when long press, and then press “OK” key, then press “start test” key to start the test, when the current shows about 1mA (1000uA) The voltage value is U1mA value (breakdown voltage). At this time, you can press the "Start Test" button again to view the leakage current value of the varistor under test. If you want to end the test, you can directly press the "Exit" button or press the "Start Test" button to end the test while viewing the varistor leakage current value.

4. Discharge tube test

During measurement, press the "Type Selection" key to select the test type as "discharge tube" and clamp the discharge tube under test (as shown in the figure). Press the "Start Test" button to start the test. At this time, you can see that the voltage value is continuously rising. When the voltage value stops, it means that the test is completed.

5. Insulation resistance test

During the measurement, press the "Type Selection" key to select the test type as "insulation resistance", and clamp the insulation resistance to be measured like a varistor. Press the "Start Test" button to start the test. There is a prompt "Testing ..." in the lower right corner of the screen. About 15s after the test starts, the test will be automatically stopped. If you want to interrupt the test in advance, you can directly press the "Exit" button.

6. Backlight control

After booting, long press the "Exit" key to enter the backlight brightness adjustment page, and press the left "" and right "" direction keys to adjust the backlight brightness.

7. Conformity judgment setting

After booting, press the "OK" button to enter the qualification judgment mode. At this time, you can see the text box below the screen flashing, indicating that the item is being set. Press the upper “” key or the lower “” (short press plus or minus 1 when adjusting the upper and lower limits, long press plus or minus 50) to adjust the parameters, and press the left “” or right “” key to change the cursor position. When the conformity judgment state is adjusted to the "on" state, the conformity judgment can be turned on, otherwise the conformity judgment is turned off. "U:" on the right is the judgment voltage range. The value in the box on the left is the lower limit of the judgment, and the value on the right is the upper limit. "Pass" is displayed in the "Status" box and a buzzer sounds, no

8. Data storage

After the power is turned on, the measurement is completed. Short press the "Storage / Review" key to save the data once. When saving, the word "H" is displayed in the upper right corner of the screen. After saving, the word "H" disappears, and the data saving operation is completed. More than 500 sets of data can be saved, and the box on the right side of the "stored data" in the test interface displays the number of saved data sets.

9. Data access / deletion

When the data is stored, long press the "storage / search" button to check the saved data after the power is turned on. At this time, the word "MR" is displayed in the upper right corner of the screen. Press the left "", right "" to browse the stored data The serial number of the saved data is displayed in the box to the right of "Stored Data". In the data review state, short press the "Storage / Review" key to exit the data review state. If there is no data saved, long press the "Storage / Review" button to display "NULL" in the upper right corner of the screen, indicating that there is no stored data, and the test interface will be automatically skipped.

In the data review state, long press the "Storage / Review" key to jump to the delete data page. Press the left “” and “” right keys to select “Yes” and “No” to select whether to delete the data. Select "Yes" and press "OK" to delete all data. Select "No" and press "OK" to cancel deleting the data and return to the data review state.
