MEASUREMENT PROCEDURE
MEASUREMENT PREPARATIONS
1 . Con
fi
rm that the electrode is washed and
cleaned.
2. Con
fi
rm that a value larger than the in-
sulation resistance of a measured sample
is indicated with the insulation resistance
measured using an empty electrode. If
the measured resistance value is 10
13
Ω
,
it is necessary that the resistance value
measured using an empty electrode be
more than 10
14
Ω
. If a measured sample
insulation resistance is unknown, clean
the device so that the insulation resistance
meter used indicates the maximum value of
in
fi
nity.
MEASUREMENT
1. Remove the device tightening ring, then
pour a measured sample in the electrode
twice or three times for device washing
with the measured sample liquid.
2. Pour an approximate 25 cc sample into the
device then
fi
rmly tighten ring.
3. Connect the device to the megohmmeter
with the center conductor to (+) termi-
nal, guard on cell to guard terminal, and
counter electrode to (-) terminal on the
megohmmeter using the supplied cables
and adapter.
4. Cell should be placed on insulator during
testing and should not be touched during
testing.
5. Sample volume resistivity becomes as
follows: Volume resistivity = Measured
insulation resistance from meter * Cell
Constant (
Ω
*cm)
6. Cell Constant is ____492______cm
