2. ຂໍ້ມູນຄວາມປອດໄພ
ຄຳເຕືອນ: This device measures high voltages. Failure to follow safety precautions can result in serious injury or death. Always adhere to the following safety guidelines:
- Always connect the probe's ground lead to the oscilloscope's ground terminal before connecting the input leads to the circuit under test.
- Ensure the probe is rated for the maximum voltage of the circuit being tested. The N1070A has a maximum differential test voltage of 7kVp-p.
- ບໍ່ເກີນປະລິມານການປ້ອນຂໍ້ມູນສູງສຸດtage ratings specified in the technical specifications.
- Inspect the probe, leads, and accessories for any damage before each use. Do not use if any part is damaged.
- Operate the probe only in dry conditions. Avoid exposure to moisture or extreme temperatures.
- Use only the provided adapter or appropriate batteries for power.
- Refer to your oscilloscope's manual for proper connection and operation procedures.

4. ຕັ້ງຄ່າ
- ການສະຫນອງພະລັງງານ: The N1070A probe can be powered by either the included power adapter or internal batteries (not included).
- To use the adapter, connect it to the probe's power input jack and then to a suitable power outlet.
- To use batteries, open the battery compartment (refer to the diagram on the probe unit) and insert the required batteries, ensuring correct polarity.
- Connect to Oscilloscope: Connect the BNC cable from the N1070A probe's output to an input channel on your oscilloscope. Ensure the connection is secure.
- Select Attenuation: On the N1070A probe unit, select the desired attenuation ratio (100X or 1000X) using the switch. This setting determines the probe's voltage division ratio.
- Oscilloscope Settings: Set your oscilloscope's input impedance to 1MΩ. Adjust the vertical scale (Volts/Div) on your oscilloscope according to the selected attenuation ratio. For example, if the probe is set to 100X, a 1V/Div setting on the oscilloscope will represent 100V/Div at the probe tips.
5. ຄໍາແນະນໍາການດໍາເນີນງານ
- ເປີດ: Turn on the N1070A probe using the power switch. The power indicator light should illuminate.
- Zero Offset: The probe features a built-in auto-zero function. Allow a few moments for the probe to stabilize after powering on.
- ເຊື່ອມຕໍ່ກັບວົງຈອນ: Carefully connect the red and black input leads of the differential probe to the two points in the circuit where you wish to measure the voltage difference. Use the provided probe hooks for secure connection.
- Observe Waveform: Observe the waveform on your oscilloscope. Adjust the oscilloscope's time base and vertical scale as needed for a clear display.
- ການປ້ອງກັນການໂຫຼດເກີນ: The probe includes overload protection. If the input voltage exceeds the probe's limits, the output may clip or distort. Disconnect immediately and verify the voltage ຊ່ວງ.
- ປິດພະລັງງານ: After use, disconnect the probe from the circuit under test, then turn off the probe and the oscilloscope.
6. ບໍາລຸງຮັກສາ
- ທໍາຄວາມສະອາດ: Clean the probe's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the probe is powered off and disconnected before cleaning.
- ການເກັບຮັກສາ: Store the probe in a clean, dry environment, away from direct sunlight and extreme temperatures.
- ການປ່ຽນແບັດເຕີຣີ: If using batteries, replace them when the power indicator dims or the probe malfunctions. Ensure correct polarity during replacement.
- ການກວດກາ: Regularly inspect the probe body, cables, and connectors for any signs of wear or damage.
7. ການແກ້ໄຂບັນຫາ
- ບໍ່ມີພະລັງງານ:
- Check if the power adapter is securely connected and functioning.
- ຖ້າຫາກວ່າການນໍາໃຊ້ຫມໍ້ໄຟ, ໃຫ້ແນ່ໃຈວ່າພວກເຂົາເຈົ້າໄດ້ຖືກໃສ່ຢ່າງຖືກຕ້ອງແລະບໍ່ໄດ້ຫມົດ.
- No Signal on Oscilloscope:
- Verify that the BNC cable is securely connected to both the probe and the oscilloscope.
- ໃຫ້ແນ່ໃຈວ່າໂພຣບເປີດຢູ່.
- Check the oscilloscope's input channel settings (e.g., input impedance, vertical scale).
- Confirm the probe leads are properly connected to the circuit under test.
- Distorted or Clipped Waveform:
- ປະລິມານການປ້ອນຂໍ້ມູນtage may exceed the probe's maximum rating for the selected attenuation. Switch to a higher attenuation ratio (e.g., 1000X) or reduce the input voltage.
- Check the oscilloscope's vertical scale setting; it might be too sensitive.
