OE 4002
MULTIMETER MEGOHMETRE AND INSULATION TESTER 1000V CAT. III
R10Min= Resistance value measured 10 minutes after applying the test voltage; R1Min=R60Sec= Resistance
value measured 10 minutes after applying the test voltage; R15Sec= Resistance value measured 10 minutes after
applying the test voltage After performed insulation test, press DAR/PI button, meter display DAR; press DAR/PI
button again, meter display PI. If DAR
or PIValue invalid, themeter display - - - - .
Show the difference between actual value and the relative base.
Press
REL
Button to enter relative measurement and the meter will record the initial value when pressing the key.
Displayed value = Actual value -Initial value
Press
REL
Button again to exit relative measurement.
Sometimes an insulation part with obvious drawbacks (e.g., the insulation part is broken through under high
voltage) is nevertheless with a good absorption ratio (or polarization index). Therefore, absorption ratio
(polarization index) cannot be used to discover local insulation drawbacks other than dampness and contamination.
DAR (absorbing ratio) =
DAR (polarization index) =
To enter the Manual Range mode, press Range button and Auto is hide, In the Manual Range mode, press Range
button to increment the range. After the highest range, the Meter wraps to the lowest range.
To exit Manual Range, press Range button for one second or turn the rotary switch. The Meter returns to Autorange
and Auto is displayed.
