WARRANTY
We warrant that this product is free from defects in material and workmanship and, when properly used,
will perform in accordance with applicable IET specifications. If within one year after original shipment,
it is found not to meet this standard, it will be repaired or, at the option of IET, replaced at no charge when
returned to IET. Changes in this product not approved by IET or application of voltages or currents greater
than those allowed by the specifications shall void this warranty. IET shall not be liable for any indirect,
special, or consequential damages, even if notice has been given to the possibility of such damages.
THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR ANY PARTICULAR PURPOSE.

WARNING
OBSERVE ALL SAFETY RULES
WHEN WORKING WITH HIGH VOLTAGES OR LINE VOLTAGES.
Dangerous voltages may be present inside this instrument. Do not open the case
Refer servicing to qualified personnel
HIGH VOLTAGES MAY BE PRESENTAT THE TERMINALS OF THIS INSTRUMENT
WHENEVER HAZARDOUS VOLTAGES (> 45 V) ARE USED, TAKE ALL MEASURES TO
AVOID ACCIDENTAL CONTACT WITH ANY LIVE COMPONENTS.
USE MAXIMUM INSULATION AND MINIMIZE THE USE OF BARE
CONDUCTORS WHEN USING THIS INSTRUMENT.
Use extreme caution when working with bare conductors or bus bars.
WHEN WORKING WITH HIGH VOLTAGES, POST WARNING SIGNS AND
KEEP UNREQUIRED PERSONNEL SAFELY AWAY.
CAUTION
DO NOT APPLY ANY VOLTAGES OR CURRENTS TO THE TERMINALS OF THIS
INSTRUMENT IN EXCESS OF THE MAXIMUM LIMITS INDICATED ON
THE FRONT PANEL OR THE OPERATING GUIDE LABEL.

MEASUREMENT PROCEDURE
MEASUREMENT PREPARATIONS
1 . Confirm that the electrode is washed and
cleaned.
2. Confirm 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 1013 Ω,
it is necessary that the resistance value
measured using an empty electrode be
more than 1014 Ω. If a measured sample
insulation resistance is unknown, clean
the device so that the insulation resistance
meter used indicates the maximum value of
infinity.
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 firmly 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
