If the voltage present is:
„ AC, the indicators light to indicate its value and the + (green)
and - (orange) indicators light.
„ DC, the indicators light to indicate its value and the + in-
dicator (green) or the - indicator (orange) lights to indicate
the polarity.
„ hazardous (>50 Vac or 120 Vdc): the higher the voltage,
the faster the ELV indicator (red) flashes; the device also
emits audible beeps.
ELV: Extra Low Voltage. This redundant indicator indicates
that the voltage is greater than the ELV.
The first two indicators of the bargraph are green to
indicate that the voltage is not hazardous and the device
does not beep. The remaining indicators are red and the
device beeps.
If only the ELV indicator lights, the batteries are low or
missing.
If there is a voltage near the element being tested, the device
may indicate the presence of an operating voltage on the
element being tested.
