4. Setup
4.1 Unpacking and Inspection
Carefully unpack the ScopeMeter and all accessories. Inspect for any signs of damage. If any items are missing or damaged, contact your supplier immediately.
4.2 Battery Installation and Charging
The device uses a Lithium-Ion battery. Ensure the battery is properly installed. Connect the power adapter to charge the device before first use. A full charge is recommended for optimal battery life.
4.3 Initial Power On
Press and hold the power button until the display illuminates. The device will perform a self-test. Follow any on-screen prompts for initial setup, such as language selection.
5. Operating Instructions
5.1 Basic Measurement Modes
The ScopeMeter offers both oscilloscope and multimeter functionalities. Use the dedicated buttons to switch between modes.

5.3 IntellaSet™ Technology
IntellaSet analyzes measured waveforms using a unique algorithm and automatically displays the most appropriate measurement values on the screen. This simplifies waveform analysis and ensures reliable verification of readings.
5.4 Long-Term Recorder Function
The recorder function allows high-speed and long-term waveform capture. It can capture up to 400M samples and record up to 15G points of data directly to an SD card (for 124B and 125B models). This enables saving up to 14 days of event data for later analysis.
5.5 Using the Multimeter
Switch to multimeter mode to perform standard electrical measurements such as voltage, current, resistance, and capacitance. Refer to the on-screen interface for specific measurement selections and ranges.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery; power button not pressed correctly. | Charge the battery; ensure the power button is pressed firmly for a few seconds. |
| Unstable waveform display. | Incorrect trigger settings; poor probe connection. | Ensure Connect-and-View is active or adjust trigger levels manually; check probe connections. |
| Inaccurate multimeter readings. | Incorrect measurement mode; faulty probes. | Verify the selected measurement mode; test probes for continuity or replace if damaged. |
| SD card recording issues. | SD card full or corrupted; incorrect file format. | Check SD card capacity; format the SD card (this will erase data); try a different SD card. |
If the problem persists after attempting these solutions, contact customer support.
