1.1 International Electrical Symbols
This symbol signifies that the instrument is protected by double or reinforced
insulation.
This symbol on the instrument indicates a WARNING and that the operator must refer
to the user manual for instructions before operating the instrument. In this manual,
the symbol preceding instructions indicates that if the instructions are not followed,
bodily injury, installation/sample and product damage may result.
Risk of electric shock. The voltage at the parts marked with this symbol may be
dangerous.

Remote Test Probe
• Theyellowtestbuttongeneratesthetestvoltagewhenpressed.
• The push-button on the back of the probe allows you to light the test point
(approx 500 lux of light). This function is very useful, since insulation testing is
performed on de-energized installations, which can be in a dark area.
