2. Open the cover and insert the provided 18650 lithium battery, ensuring correct polarity.
3. Tanqueu bé la tapa del compartiment de la bateria.

4.2 Engegada/apagada

• Per encendre: Premeu el botó PODER botó breument.
• Per apagar: Manteniu premut el botó PODER botó fins que la pantalla s'apagui.

4.3 Bluetooth Connection and App Installation

1. Download the "i-meter" application from your smartphone's app store (available for Android and iOS).
2. Ensure Bluetooth is enabled on your smartphone and on the CMS101 device.
3. Open the i-meter app and follow the on-screen instructions to pair with your CMS101 device.
4. Once connected, you can remotely control the device and access data recording features.

5. Funcionament

5.1 Switching Modes (Multimeter / Oscilloscope)

After powering on, briefly press the PODER per alternar entre el mode multímetre digital (DMM) i el mode oscil·loscopi (OSC).

5.2 clamp Meter (AC/DC Current Measurement)

El clamp meter function allows for non-contact measurement of AC and DC current up to 1000A.

1. Ensure the device is in DMM mode.
2. Press the jaw release trigger to open the clamp mandíbula.
3. Col·loca el clamp jaw around a single conductor (not a bundle of wires) through which the current flows. Ensure the jaw is fully closed.
4. Llegiu el valor actual que es mostra a la pantalla LCD.
5. Use the function buttons (F1-F4) to select AC or DC current measurement if not auto-ranging.
