The pointer megohmmeter adopts the embedded industrial single-chip real-time operating system, and the ultra-thin-shaped wire head is perfectly combined with the graphic dot-matrix liquid crystal display. The series has various voltage output levels, large capacity, strong anti-interference, and pointer and digital synchronization. Display, AC and DC, simple operation, automatic calculation of various insulation indicators, various measurement results with anti-power failure function.
First, preparation work 1, the test equipment should be removed before the test equipment power supply and all external wiring, and the test object shorted after grounding discharge 1min, the larger capacity should be discharged for at least 2min to avoid electric shock and affect the measurement results.
2. Verify that the meter pointer is at infinity, otherwise you need to adjust the mechanical zero adjustment screw.
3. Wipe the surface dirt of the test object with a dry and clean soft cloth. If necessary, first clean the surface area of ​​the casing with gasoline to eliminate the surface leakage current and affect the test results.
4. Insert one end of the shielded high voltage test lead (red) into the (1) LINE end, and the other end (red) is connected to the high voltage conductor of the device under test. Insert the shielded high voltage test line shield (black) (2) GROUND The other end is connected to the high voltage protection ring of the equipment under test to eliminate the influence of surface leakage current (see “How to use the shielding endâ€. Insert another black test line into the ground (EARTH) (3) The other end is connected to the outer casing or the ground of the equipment under test.
Second, start testing
1. Turn on the power switch. At this time, the power indicator on the switch should be lit.
2. The whole machine starts self-test and an operation prompt appears on the LCD screen.
3. Press the voltage selection button (16) to select the desired test voltage (2.5KV or 5KV). If you do not select a voltage, you can proceed to the next step.
4. Press the page flip button (13) to select the test number. (Number anti-black) If you do not select the number, you can proceed to the next step. The number is automatically accumulated after the test is completed.
5. Press the test button (14) to start the test. At this time, the high-voltage status indicator lights up and the built-in buzzer sounds every 1 second, indicating that there is a high-voltage output at the LINE end.
6. At this time, the LCD screen enters the test status display mode.
7. The meter emits a beep at regular intervals (15 seconds, 1 minute, 10 minutes).
8. Press the test button again according to the required test results (common test, absorption ratio test, polarization index test).
9. When the second measurement needs to be performed continuously, press the test button (14) again to return to the selection test number state and follow the steps 4-7.
Third, access to test results
1. In the state of selecting the test number, press the function key (15) to enter the history test result state.
2. Press the page up button (13) and the voltage selection button (16) to increase and decrease the number of the test result. (The corresponding number is anti-black).
3. After selecting the number, press the test button (14) to enter the test result of the number, press the page up button (13) to read the test result (current resistance, 15 seconds resistance, 60 seconds resistance) Value, 10-minute resistance, absorption ratio, polarization index).
4. After the review is completed, press the function key (15) to return to the ready test state.
How to read the pointer megohmmeterThe scale value of the pointer type megger is increased from right to left, so if the pointer is just on the scale line, read it directly; if it is not on the scale line, read the nearest scale on the right side of the pointer. The value, plus the estimate between the left and right side scales of the pointer. For example, if the pointer is between 5 and 6, the reading is approximately 5.5 megohms and the pointer is between 10 and 15, and the reading can be read as approximately 12 megohms. It should be noted that the scale of the megohmmeter is not linear, but approximates the logarithmic relationship. This should be noted when reading. In addition, the mechanical zero point of the pointer must be adjusted first.
The utility model provides a disposable electronic cigarette, comprising: a hollow shell, the bottom of the shell is provided with a lower cover; the shell contains an atomizer, and the outer side of the atomizer is sheathed with a disposable cigarette A bomb, a microphone cover is arranged under the atomizer, a microphone is covered under the microphone cover, a battery is arranged on one side of the atomizer, and an upper cover is arranged on the top of the casing; The atomizer includes an atomizing core, an oil-absorbing cotton sleeved on the outside of the atomizing core, and an atomizer outer tube sleeved on the outside of the oil-absorbing cotton. The disposable electronic cigarette provided by the utility model absorbs the smoke oil on the surface through the absorbing cotton, and then atomizes the smoke through the atomizing core, which greatly reduces the risk of oil leakage, at the same time, reduces the burning of cotton and ensures the smoking taste.The utility model provides a disposable electronic cigarette, comprising: a hollow shell, the bottom of the shell is provided with a lower cover; the shell contains an atomizer, and the outer side of the atomizer is sheathed with a disposable cigarette A bomb, a microphone cover is arranged under the atomizer, a microphone is covered under the microphone cover, a battery is arranged on one side of the atomizer, and an upper cover is arranged on the top of the casing; The atomizer includes an atomizing core, an oil-absorbing cotton sleeved on the outside of the atomizing core, and an atomizer outer tube sleeved on the outside of the oil-absorbing cotton.
