5. Setup
Follow these steps to set up your VOLTCRAFT DOV1254 LA Digital Oscilloscope for initial use:
- Pjazzament: Place the oscilloscope on a stable, level surface with adequate ventilation around the unit.
- Konnessjoni tal-Enerġija: 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.
- Konnessjoni tas-Sonda: 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.
- Kumpens tas-Sonda: 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.
- Qawwa Mixgħul: Press the power button located on the front panel to turn on the oscilloscope.
6. Operating the Oscilloscope
This section covers basic operational procedures for the VOLTCRAFT DOV1254 LA.
