in section 1.2.
Caution, risk of Do not expose
electric shock
• The user must have read and understood these safety instructions.
• Failure to heed these warnings may result in serious or fatal personal injury
and/or property damage.
• Do not use or modify this device for any purpose other than for which it
was designed.
• Do not make any technical changes or modifications to the device or
defeat any safety functions.
• Use only original accessories and spare parts.
• The manufacturer disclaims liability for any damage or malfunction
resulting from failure to observe these operating and maintenance
instructions.
• The illustrations and pictures may differ from the actual device, but the
functions and required procedures remain the same.
Safety precautions
Preliminary remark
• Due to the increasing probability of high transient overvoltage in modern
power systems, electrical test equipment must meet more stringent safety
standards. Transients in electrical systems (power grid, feeders or branch
circuits) can trigger a sequence of incidents that may result in serious
personal injury. Safety must be built into test equipment to protect users
against transients.
