Operating Information
TDS3000C Series S ervice Manual

WARNING. To avoid electric shock, always connect the rear-panel ground
terminal to earth ground when operating the instrument from battery power.
For safe operation, the oscilloscope chassis must remain at earth ground potential
even when operating from battery power. Without a connection between the
chassis and earth ground, you can receive a shock from exposed metal on the
chassis if you connect an input to a hazardous voltage (>30 V
RMS
, >42 V
pk
). To
protect against this condition, attach the Tektronix-supplied grounding wire from
the terminal on the rear panel to earth ground. If you use a different grounding
wire, it must be larger than 18 gauge (1 mm
2
).
When you start to use the battery pack, an on-screen message reminds you to
connect the grounding wire between the ground terminal on the rear panel and
earth ground.
