5. Installation

Follow these steps to set up your VOLTCRAFT DOV1254 LA Digital Oscilloscope for initial use:

1. Placement: Place the oscilloscope on a stable, level surface with adequate ventilation around the unit.
2. Connexion électrique : Connect the supplied power cord to the power input on the rear panel of the oscilloscope, then plug the other end into a grounded AC power outlet.
3. Connexion de la sonde : Connect the passive probes to the desired BNC input channels (CH1-CH4) on the front panel. Ensure a secure connection by twisting the BNC connector until it locks.
4. Compensation de la sonde : Before taking measurements, it is recommended to compensate the probes. Connect the probe tip to the probe compensation output (usually a square wave signal) and adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.
5. Mise sous tension : Appuyez sur le bouton d'alimentation situé sur le panneau avant pour allumer l'oscilloscope.
