1Characteristics and Specifications
Measurement Category
Measurement Category
The InfiniiVision 1000 X-Series oscilloscope is intended to be used for
measurements in Measurement Category I.
Measurement Category Definitions
Measurement category I is for measurements performed on circuits not directly
connected to MAINS. Examples are measurements on circuits not derived from
MAINS, and specially protected (internal) MAINS derived circuits. In the latter
case, transient stresses are variable; for that reason, the transient withstand
capability of the equipment is made known to the user.
Measurement category II is for measurements performed on circuits directly
connected to the low voltage installation. Examples are measurements on
household appliances, portable tools and similar equipment.
Measurement category III is for measurements performed in the building
installation. Examples are measurements on distribution boards, circuit-breakers,
wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the
fixed installation, and equipment for industrial use and some other equipment, for
example, stationary motors with permanent connection to the fixed installation.
Measurement category IV is for measurements performed at the source of the
low-voltage installation. Examples are electricity meters and measurements on
primary overcurrent protection devices and ripple control units.
Transient Withstand Capability
WARNING
Use this instrument only for measurements within its specified measurement category.
CAUTION
Maximum input voltage for analog inputs and external trigger input:
150 Vrms, 200 Vpk

Characteristics and Specifications 1
1000 X-Series Oscilloscopes Service Guide 15
Environmental Conditions
Environment Indoor use only.
Ambient
temperature
Operating: 0 °C to +50 °C
Non-operating: –40 °C to +70 °C
Humidity Operating: Up to 95% RH at or below +40 °C (non condensing)
Non-operating: Up to 90% RH up to +65 °C (non condensing)
Altitude Operating: Up to 3,000 m
Non-operating: Up to 15,300 m
Overvoltage
Category
This product is intended to be powered by MAINS that comply to Overvoltage
Category II, which is typical of cord-and-plug connected equipment.
Pollution Degree The InfiniiVision 1000 X-Series oscilloscopes may be operated in environments
of Pollution Degree 2 (or Pollution Degree 1).
Pollution Degree
Definitions
Pollution Degree 1: No pollution or only dry, non-conductive pollution occurs.
The pollution has no influence. Example: A clean room or climate controlled
office environment.
Pollution Degree 2. Normally only dry non-conductive pollution occurs.
Occasionally a temporary conductivity caused by condensation may occur.
Example: General indoor environment.
Pollution Degree 3: Conductive pollution occurs, or dry, non-conductive
pollution occurs which becomes conductive due to condensation which is
expected. Example: Sheltered outdoor environment.

2Testing Performance
Overview
Let the Equipment Warm Up Before Testing
For accurate test results, let the test equipment and the oscilloscope warm up
30 minutes before testing.
Verifying Test Results
During the tests, record the readings in the Performance Test Record on page 39.
To verify whether a test passes, verify that the reading is within the limits in the
Performance Test Record.
If a performance test fails
If a performance test fails, first perform the User Cal procedure. Press the following keys to access User
Cal: [Utility]→Service→Start User Cal.
