CAUTION
Do not exceed the maximum specified front panel terminal CH1, CH2 (or
CH3 and CH4 on 4 channel models), and EXT TRIG voltage levels. Refer to
Specifications for more details.
Safety Certification
The design of the instrument has been verified to conform to applicable EN
61010-1, UL 61010-1 2nd Edition and CSA C22·2 No·61010-1-04 safety
standards for the following limits:
Installation (Overvoltage) Categories II (Mains Supply Connector) & I
(Measuring Terminals).
Pollution Degree 2.
Protection Class I.
PLEASE NOTE THE FOLLOWING:
Installation (Overvoltage) Category II refers to 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.
Pollution Degree 2 refers to an operating environment where
normally only dry non-conductive pollution occurs. Conductivity
caused by temporary condensation should be expected.
Protection Class 1 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.
Cooling
The instrument relies on forced air cooling with an internal fan and
ventilation openings. Care must be taken to avoid restricting the airflow
around the apertures (fan holes) at the sides of the oscilloscope.
