3. Installation

3.1 Chargement de l'appareil

Before initial use, fully charge the DST-210. Connect the provided Type-C charging cable to the device's Type-C port and a compatible USB power adapter (5V/1A). The battery indicator on the display will show charging status.

3.2 Connexion des sondes

For accurate measurements, ensure probes are correctly connected:

• Multimeter Measurements: Insert the red test lead into the VΩHzmA or 10A jack (depending on the measurement) and the black test lead into the COM jack.
• Oscilloscope Measurements: Connectez le haut volume P6100tage probe to the oscilloscope input jack. Ensure the probe's attenuation setting (e.g., X1 or X10) matches the device's setting for accurate readings.
• Sortie du générateur de signaux : Connect the output cable to the signal generator output port.

4.3 Fonctionnement du multimètre

In Multimeter mode, the device offers various measurement functions:

• Voltage/Current (DC/AC): Select the appropriate DC V, AC V, DC A, or AC A setting. Connect test leads to the circuit. The device supports a record mode that displays measurement trends graphically, and can store up to 10 sets of data.
• Résistance (Ω) : Select the resistance function. Connect test leads across the component.
• Capacité (F): Select the capacitance function. Connect test leads across the capacitor.
• Fréquence (Hz) : Select the frequency function. Connect test leads to the signal source.
• Test de diodes : Select the diode function. Connect test leads across the diode to check its forward voltage goutte.
• Test de continuité : Select the continuity function. Connect test leads across a conductor; a beep indicates continuity.
• Température: Use a K-type thermocouple (not included) connected to the appropriate jacks for temperature measurement.
• LIVE Function: For single-probe voltagdétection de présence.
