Getting Started
Current Probe Scaling
Current probes provide a voltage signal proportional to the current. You need to
set the oscilloscope to match the scale of your current probe. The default scale is
10 A/V.
To set the scale, follow these steps:
1. Push a vertical channel button (such as the Channel 1 Menu button).
2. Push the Probe option button.
3. Push the Current option button.
4. Push the Scale option button to select an appropriate value.
Self Calibration
The self calibration routine lets you optimize the oscilloscope signal path for
maximum measurement accuracy. You can run the routine at any time but you
should always run the routine if the ambient temperature changes by 5 °C (9 °F)
or more. The routine takes about two minutes.
For accurate calibration, power on the oscilloscope and wait twenty minutes to
ensure it is warmed up.
To compensate the signal path, disconnect any probes or cables from the input
connectors. Then, access the
Utility ► Do Self Cal option, and follow the
directions on the screen.
