Note:
Installation (Overvoltage) Category II refers to the local distribution level, which is
applicable to equipment connected to the mains supply (AC power source).
Installation (Overvoltage) Category I refers to signal level, which is applicable to
equipment measuring terminals that are connected to source circuits in which
measures are taken to limit transient voltages to an appropriately low level.
Degree of Pollution II refers to a working environment which is dry and non-
conductive pollution occurs. Occasional temporary conductivity caused by
condensation is expected.
Degree of Protection I refers to grounded equipment, in which protection against
electric shock is achieved by basic insulation and by means of a connection to the
protective ground conductor in the building wiring.

2.3 Cooling Requirements
This instrument relies on the forced air cooling with internal fans and ventilation
openings. Care must be taken to avoid restricting the airow around the apertures
(fan holes) at each side of the scope. To ensure adequate ventilation it is required
to leave a 15 cm (6 inch) minimum gap around the sides of the instrument.
CAUTION: Do not block the ventilation holes located on both sides of
the scope.
CAUTION: Do not allow any foreign matter to enter the scope through
the ventilation holes, etc.
2.4 AC Power
The instrument operates with a single-phase, 100 to 240 Vrms (+/-10%) AC power
at 50/60 Hz (+/-5%), or single-phase 100 - 120 Vrms (+/-10%) AC power at 400Hz
(+/-5%).
No manual voltage selection is required because the instrument will automatically
adapt to the line voltage.
Depending on the type and number of options and accessories (probes, PC
port plug-in, etc.), the instrument can consume up to 100 W of power.

4 Getting Started
4.1 Power on
T3DSO3000 provides two ways to power it on:
1. Power on Line
When the “Power on Line” option is enabled, once the oscilloscope is connected
to the AC power supply through the power cord, the oscilloscope boots
automatically. This is useful in automated or remote applications where physical
access to the instrument is dicult/impossible.
Steps for enabling the “Power on Line” function:
Utility＞Power On Line
2. Power on manually
When the "Power on Line” option is disabled, the power button on the front
panel is the only control for the power state of the oscilloscope.

5 Probe
The T3DSO3000 series oscilloscope package includes passive probes as
standard accessories. Please visit www.teledynelecroy.com for technical data and
information on the full range of probes available.
Probe Compensation
When a probe is used for the rst time, you should compensate it to match the
input channel of the oscilloscope. Non-compensated or poorly compensated
probe may increase measurement inaccuracy or error. The probe compensation
procedures are as follows:
1. Connect the coaxial cable interface (BNC connector) of passive probe to
any channel of the oscilloscope.
2. Connect the probe to the “Compensation Signal
Output Terminal” (Cal) on the front of the
oscilloscope. Connect the ground alligator clip of
the probe to the “Ground Terminal” under the
compensation signal output terminal.
3. Press the Auto Setup button.
4. Check the waveform displayed and compare it with the examples below:
5. Use a non-metallic screwdriver to adjust the low-frequency compensation
adjustment point on the probe until the waveform displayed matches the
“Perfectly compensated” example.
