. Brief ntroduction
FR9010lightningprotectionspecial standard resistor consistsof91/2Whigh precision
militarygradewire woundresistorseries.Whentheinstrument is calibrated,thereis no needto
changethelinefordirectshifting.Thetest is convenient,thehighestprecisionis upto 0.05%,
andthelong-termstabilityis good.Itisaspecialstandardresistorspeciallydesignedbyour
company.Its resistancevalueincludes1mΩ,10mΩ,100mΩ,1Ω,10Ω,100Ω,1KΩ,10KΩ,
100KΩ.Itfullymeets therangeof10-3~105asspecifiedinOrder No.31ofthe 《Measures
fortheAdministrationofDetectingQualifications ofLightningProtection Devices》.Mainly
usedforcalibrationofgrounding resistancetester, equipotentialtester, etc.

V. Operation Method
Do not applymorethan 1/2W ofcapacity factor totheresistor,
otherwise the standard resistor will be damaged.
When calib
ratingthe instrument,it must becalibratedusingthe
four-
wire method,otherwisemeasurementaccuracycannotbe
guaranteed.
If youusethisstandardresistorto verify otherinstruments,
use the four-wire method whenever possible. If using the two-wire
method,use the C1 and C2 terminals.
Whencalibratingvariousresistancetestinstruments,first confirm thattheoutput power of
theinstrument doesnotexceedthecapacityfactorofthemeasuredresistance andthentest it.
Whentesting, usethefour-wiremethod asmuchaspossible.
Thewiring diagramsofvariousinstrumentsareasfollows.Afterconnectingtherear line,
hitthecorresponding fileandstarttheinstrument to betested.
