Safety Summary
Specific Precautions Observe all the following precautions to ensure your personal safety and to prevent damage to either the oscilloscope or equipment connected to it.
Do Not Perform Service While Alone
Do not perform internal service or adjustment of this product unless another person capable of rendering first aid and resuscitation is present.
Use Care When Servicing With Power On
Dangerous voltages exist at several points in this product. To avoid personal injury, do not touch exposed connections or components while power is on. Disconnect power before removing protective panels, soldering, or replacing components.
Power Source
The TDS 310, TDS 320, and TDS 350 operate from a power source that does not apply more than 250 VRMS between the supply conductors or between either supply conductor and ground. A protective ground connection, through the grounding conductor in the power cord, is essential for safe system operation.
Grounding the Oscilloscope
The oscilloscope is grounded through the power cord. To avoid electric shock, plug the power cord into a properly wired receptacle with an earth ground connection. Do this before making connections to the input or output terminals of the oscilloscope.
Without the protective ground connection, all parts of the oscilloscope are potential shock hazards. This includes knobs and controls that may appear to be insulators.
Use the Proper Power Cord
Use only the power cord and connector specified for your product. Use only a power cord that is in good condition.
Use the Proper Fuse
To avoid fire hazard, use only a fuse that meets all type, voltage, and current specifications on page 1-13.
Do Not Remove Covers or Panels
To avoid personal injury, do not operate the oscilloscope without the panels or covers.

Safety Summary
Do Not Operate in Explosive Atmospheres
The oscilloscope provides no explosion protection from static discharges or arcing components. Do not operate the oscilloscope in an atmosphere of explosive gasses.
Electric Overload
Never apply a voltage to a connector on the oscilloscope that is outside the range specified for that connector.

1The trigger position errors are typically less than the values given here. These values are for triggering signals having a slew rate at the trigger point of ±0.5 division/ns.
2The waveform interval (WI) is the time between the samples in the waveform record. Also, see the footnote for the characteristics
Sample Rate Range and Equivalent Time or Interpolated Waveform Rates in Table 1<11 on page 1<12.
3The minimum sensitivity for obtaining a stable trigger. A stable trigger results in a uniform, regular display triggered on the selected slope. The trigger point must not switch between opposite slopes on the waveform, and the display must not •roll" across the screen on successive acquisitions. The TRIG'D LED stays constantly lighted when the SEC/DIV setting is 2 ms or faster but may flash when the SEC/DIV setting is 10 ms or slower.

1Displayed vertically with 25 digitization levels (DLs) per division and 10.24 divisions dynamic range with zoom off. A DL is the smallest voltage level change that the 8;bit A;D Converter can resolve, with the input scaled to the volts/division setting of the channel used. Expressed as a voltage, a DL is equal to 1/25 of a division times the volts/division setting.
2The sensitivity ranges from 2 mV/div to 10 V/div in a 1-2-5 sequence of coarse settings. Between consecutive coarse settings, the sensitivity can be finely adjusted with a resolution of 1% of the more sensitive setting. For example, between 50 mV/div and 1009mV/div, the volts/division can be set with 0.5 mV resolution.

1The range of real.time rates, expressed in samples/second, at which a digitizer samples signals at its inputs and stores the samples in memory to produce a record of time.sequential samples
2The Waveform Rate (WR) is the equivalent sample rate of a waveform record. For a waveform record acquired by real.time sampling of a single acquisition, the waveform rate is the same as the real.time sample rate; for a waveform created by interpolation of real.time samples from a single acquisition or by equivalent.time sampling of multiple acquisitions, the waveform rate is faster than the real time sample rate. For all three cases, the waveform rate is 1/(Waveform Interval) for the waveform record, where the waveform interval (WI) is the time between the samples in the waveform record.
