The calibration output (3Vpp, 1kHz) for the probe is underneath the battery cover.
To remove the battery cover, use a coin to turn the slot on the back of the unit counter-
clockwise.
Connect the probe to be adjusted
to the calibration output under the
battery housing cover, as shown.
• Select the DC coupling for the channel to which the probe is connected and run
an Autoset
to carry out pre-setting.
• Adjust the sensitivity and the vertical offset of the channel so that the signal fills
the screen, and adjust the time base to 200µs to view a signal period on the
screen.
• Turn the BNC base of the probe in order to access the probe adjustment screw:
In this example, the probe is over-compesated:
an overshoot occurs.
Turn the screw in either direction until the
signal is horizontal and looks like the screen
shown opposite. Your probe is now calibrated.
Turn the BNC base again to close access to
the adjustment screw and replace the battery
cover.
Remote Programming
The oscilloscope can be programmed remotely from a computer by using the SX-
METRO software, which is located on the CD-ROM supplied with your instrument. This
software is used to:
• Configure the instrument
• Perform measurements and retrieve the results
• Transfer files (traces, configuration, screenshots, etc.)
To communicate between the instrument and the computer:
• Connect the USB end of the cable to one of the PC’s USB ports (if necessary
install the driver shipped with the cable).
• Connect the optical connector to the oscilloscope, after first powering it up.
• Open SX-METRO; select USB communications and wait for communication to
be established (in the event of a problem, refer to the SX-METRO instructions).
