Functional Check
NOTE. If your instrument supports probe calibration routines, now is
a good time to perform them.
6. Disconnect the probe from the SIGNAL terminal and ground the
probe tip. (Connect the KlipChip to the probe tip.)
7. With the probe offset set to 0.0 V, the oscilloscope display should
be at the ground reference.
8. Set the oscilloscope volts/division to 5 V.
9. Adjust the probe offset. The displayed waveform should vary
between approximately +10 V and - - 10 V. (A +10 V offset
displays a - - 10 V level on your instrument.)
NOTE. If no waveform is displayed, check the vertical coupling to be
sure that it is set to DC.
If the offset adjustment has no effect, set the vertical coupling to DC.
If you are using the Tektronix 1103 Probe Power Supply, and the
waveform is distorted, check to make sure that the oscilloscope
termination is 50 Ω.
If the probe does not pass this functional check, go to the Trouble-
shooting section of this manual.
