DIGITAL INSULATION TESTER
2 seconds within 15s.
b) Display Indicators
The Primary Display：Indicate the current function testing
values
The Secondary Display： It shows the output DCV while you
test the insulation resistance, and the battery voltage while
the ACV
The Analog Bar： indicate the current function testing value in
synchronous with the primary display.
:While testing the insulation resistance, the symbol
" " flashes frequently if the voltage is over 30V.
•))) : While testing the insulation resistance, the symbol" •)))
" flashes
continually if the
outside voltage is over 30V. the symbol " •))) " is
indicated
while LOΩ≤35Ω and the BZ warns continuously.
LOCK：Push down the "LOCK" button while you test the
insulation resistance and the symbol "
indicated.
