Maintenance

Topics in this section describe procedures for keeping the instrument in optimal working condition.

Fuse Replacement

Disconnect the power cord before inspecting or replacing the fuse. Open the fuse holder (located at the

rear of the instrument below the AC power inlet) using a small, flat-bladed screwdriver. Replace the old

fuse with a new 5 x 20 mm T-rated 3.15 A/250 V fuse. Close the fuse holder before powering on.

Caution: For continued fire protection at all line voltages, replace the fuse with one of the specified

type and rating only. Always disconnect the power cord before replacing the fuse.

Touch Screen Calibration

Periodically calibrate the touch screen to maintain its accuracy and responsiveness. We recommend that

you use a stylus rather than your finger for this procedure.

1. From the menu bar, choose Utilities > Utilities Setup.

2. On the Utilities main dialog, touch Touch-Screen Calibration.

3. Following the prompts, touch as close as possible to the center of each cross that appears on the

screen until the calibration sequence is complete.

Restart/Reboot Instrument

To restart the oscilloscope application, choose File > Exit from the menu bar, then touch the Start DSO

desktop shortcut.

Note: You will generally need to exit and restart the application after adding new options keys.

To reboot the instrument, which includes restarting the OS:

1. From within the oscilloscope application, choose File > Shutdown.

2. Wait 10 seconds after the oscilloscope has fully shut down, then press the Power button on the

front of the instrument.
