Setup: Calibrating the Probe

Shaft Voltage TesterTM with calibration dongle

Now the scope is set up to calibrate the probe. The AEGIS-OSC-9100 includes a two-pronged calibration dongle that plugs into the side of the scope. This micro-USB dongle generates a square wave used to fine-tune the probe.

Calibration must be done the first time a new probe is used, and should be checked periodically to ensure accurate waveform measurements.

Calibrating the probe with the adjustment screw

Plug the dongle into the small USB port, clamp the probe ground lead to the lower prong, and touch the SVP Tip to the upper prong.

Press AUTO. The scope will display a train of approximately square waves of amplitude 3V and frequency 1 kHz.

Using the included screwdriver with insulated handle, adjust the screw in the probe until the waves are displayed with square edges. The probe is now calibrated.

Remove dongle.
