SAFETY INSTRUCTION
This chapter contains important safety instructions that should be followed when operating and storing the oscilloscope. Read the following before any operation to ensure your safety and to keep best condition for the oscilloscope.
Safety Symbols
These safety symbols may appear in this manual or on the oscilloscope.

Fuse
WARNING
• Fuse type: T1A/250V
• To ensure fire protection, replace the fuse only
with the specified type and rating.
• Disconnect the power cord before replacing the
fuse.
• Make sure the cause of fuse blowout is fixed
before replacing the fuse.
Cleaning the oscilloscope
• Disconnect the power cord before cleaning the
oscilloscope.
• Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid into the oscilloscope.
• Do not use chemical containing harsh products
such as benzene, toluene, xylene, and acetone.
Operation Environment
• Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
• Relative Humidity: < 80%
• Altitude: < 2000m
• Temperature: 0°C to 50°C
(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. the oscilloscope falls un der degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.
• Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.
• Pollution degree 2: No rmally only non-conduc tive p ol lu tion occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.
• Pollution degree 3: Conductive pollution occurs, or dry, non- conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.

Power cord for the United Kingdom
When using the oscilloscope in the United Kingdom, make sure the power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED IMPORTANT: The wires in this lead are coloured in accordance with the following code: Green/ Yellow: Earth Blue: Neutral Brown: Live (Phase)
As the colours of the wire s in main leads may not correspond with the colours marking identified in your plug/appliance, proceed as follows: The wire which is coloured Green & Yellow must be connected to the Earth
terminal marked with the letter E or by the earth symbol or Green & Yellow. The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black. The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red. If in doubt, consult the instr uctions provided with the equipment or contac t the supplier. This cable/appliance should be protected by a suitably rated and approved HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used . Any moulded mains connector that requires removal /replacement must be destroyed by removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wir es is hazardous if a engaged in live socket. Any re­wiring must be carried out in accordance with the information detailed on this label.
