6. Käyttöohjeet
This section details the primary functions of the UNI-T UT217A/UT217B.
6.1 Clamp Meter Function (AC/DC Current Measurement)
- Rotate the function dial to the 'ACA' (AC Current) or 'DCA' (DC Current) position.
- Press the jaw release trigger to open the clamp leuka.
- Enclose a single conductor (not a power cord with multiple wires) within the clamp leuka. Varmista, että leuka on täysin kiinni.
- Read the current value displayed on the LCD. The device features 20000 count true RMS automatic ranging.
- For surge current measurement (AC current only), select the appropriate function if available on the dial or via a button.
6.2 Oscilloscope Function (Waveform Measurement)
The oscilloscope function allows for simultaneous measurement of current and voltage aaltomuodot.
- Rotate the function dial to the 'Oscilloscope' position.
- Connect the test leads to the appropriate input terminals for voltage measurement, or use the clamp jaw for current waveform measurement.
- The display will show the real-time waveform. Use the function buttons to adjust parameters such as time base, voltage scale, and trigger settings as needed.
- Analyze the waveform characteristics (e.g., frequency, amplitude, shape).
6.3 Bluetooth-yhteys
The device supports Bluetooth connection to a mobile phone application for enhanced functionality.
- Download and install the official UNI-T mobile application from your device's app store.
- Varmista, että Bluetooth on käytössä matkapuhelimellasi.
- Power on the UT217A/UT217B.
- Open the UNI-T application and follow the on-screen instructions to search for and connect to your device.
- Once connected, you can transmit measurement data, analyze trends, and store readings directly on your mobile device.
