Safety Symbols - DATATEC EDU34450A Guia Del Usuario

inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-
panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that
may exceed the protection limits of the EDU34450A.
Voltages above 300 VAC rms may be measured only in circuits that are isolated from mains. However, transient
overvoltages are also present on circuits that are isolated from mains. The EDU34450A is designed to safely
withstand occasional transient overvoltages up to 2500 Vpk. Do not use this multimeter to measure circuits where
transient overvoltages could exceed this level.

Safety Symbols

Symbol Description
Caution, risk of danger (refer to the manual for specific Warning or Caution information)
Protective earth (ground) terminal.
Earth ground
CAT II IEC Measurement Category II. Inputs may be connected to mains (up to 300 VAC rms) under Category II overvoltage
300 V conditions.
The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or the like, which, if not correctly performed
or adhered to, could result in personal injury. Do not proceed beyond a WARNING sign until the indicated conditions are
fully understood and met.
The CAUTION sign denotes a hazard. It calls attention to an operating procedure, or the like, which, if not correctly
performed or adhered to, could result in damage to or destruction of part or all of the product. Do not proceed beyond
CAUTION sign until the indicated conditions are fully understood and met.
The NOTE sign denotes important information. It calls attention to a procedure, practice, condition or the like, which is
essential to highlight.
