PINTECH N1070A High Voltage Manuel d'instructions de la sonde différentielle

1. Introduction

The PINTECH N1070A is a high-performance differential probe designed for safe and accurate measurement of high voltage signals with an oscilloscope. It features a bandwidth of up to 50MHz and can handle differential voltages up to 7kVp-p, making it suitable for various power electronics and industrial applications. This manual provides essential information for the proper setup, operation, and maintenance of your N1070A differential probe.

2. Consignes de sécurité

AVERTISSEMENT: 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.
• Ne dépassez pas le volume d'entrée maximaltagvaleurs e spécifiées dans les spécifications techniques.
• 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.
• L'entretien doit être effectué uniquement par du personnel qualifié.

4. Installation

1. Alimentation: 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.
2. Se connecter à l'oscilloscope : Connect the BNC cable from the N1070A probe's output to an input channel on your oscilloscope. Ensure the connection is secure.
3. 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.
4. Paramètres de l'oscilloscope : 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. Mode d'emploi

1. Mise sous tension : Turn on the N1070A probe using the power switch. The power indicator light should illuminate.
2. Décalage zéro : The probe features a built-in auto-zero function. Allow a few moments for the probe to stabilize after powering on.
3. Raccordement au circuit : 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.
4. Observe Waveform: Observe the waveform on your oscilloscope. Adjust the oscilloscope's time base and vertical scale as needed for a clear display.
5. Protection contre les surcharges : 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 gamme.
6. Éteindre: After use, disconnect the probe from the circuit under test, then turn off the probe and the oscilloscope.

6. Entretien

• Nettoyage: 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.
• Stockage: Store the probe in a clean, dry environment, away from direct sunlight and extreme temperatures.
• Remplacement de la batterie : If using batteries, replace them when the power indicator dims or the probe malfunctions. Ensure correct polarity during replacement.
• Inspection: Regularly inspect the probe body, cables, and connectors for any signs of wear or damage.

7. Dépannage

• Pas d'alimentation :
  • Vérifiez que l'adaptateur secteur est correctement branché et fonctionne correctement.
  • Si vous utilisez des piles, assurez-vous qu'elles sont correctement insérées et non déchargées.
• No Signal on Oscilloscope:
  • Verify that the BNC cable is securely connected to both the probe and the oscilloscope.
  • Ensure the probe is powered on.
  • 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:
  • Le volume d'entréetage 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.
