Statement of Compliance
Chauvin Arnoux®, Inc. d.b.a. AEMC®Instruments
certifies that this instrument has been calibrated using
standards and instruments traceable to international
standards.
We guarantee that at the time of shipping your
instrument has met its published specifications.
NIST traceable calibration is only possible when
the Model 6474 is connected to the Ground Tester
Model 6472.
To obtain NIST calibration (for a nominal charge), the
instrument would need to be returned to our facility,
along with your Ground Tester Model 6472.
The recommended calibration interval is 12 months
and begins on the date of receipt by the customer.

2.3.1 Preparation of the GroundFlex®Adapter
TheGroundFlex®AdapterModel6474isdesignedtobeusedonlywiththeModel
6472device.Thetwoinstrumentsmustbeconnectedusingthespecialconnection
cablesupplied.TheModel6474hasnoON/OFFbutton,andispoweredonlyby
theModel6472,viathisconnectioncable.
TheModel6474isintendedprimarilytomeasurethecurrentthatowsthrough
ahigh-voltagetowertotheground.Youcanwrapupto4legsofthetowerseach
withaGroundFlex®sensorandmeasurethecurrentowingtoearththrougheach
ofthelegsorthroughseverallegs.
1. SettherotaryfunctionswitchtoGroundFlex®ontheModel6472.
 WhenyouconnecttheGroundFlex®AdapterModel6474tothe6472,aself-
testwillbegin.Duringthistest,theOVERLOADchecklightonthe6474islit.
2. Connecttherequirednumberofsensorstochannels1,2,3,and/or4.

NOTE: • The sensors have arrows to indicate a direction.
• All sensors should face the same direction.
(clockwise or counter-clockwise around the tower legs)
• All sensors should have the same number of wraps.
• Sensors should encircle both leg AND ground system.

surethecurrentowingthroughoneGroundFlex®sensor(1, 2,3, or4),or
throughseveralsensors(1,2or1,2,3),orthroughallofthesensors(1,2,3,
4).
4. Select how many times the sensor is wrapped around the conductor to be
measured(from1to4turns)usingtheSENSOR TURNSselectionswitch.
NOTE: To increase measurement sensitivity, we recommend when possible,
wrapping a maximum number of turns (up to 4) around the structure.
5. SettheSENSITIVITYswitchtothedesiredsensitivity:x1/10,x1,orx10.The
choiceofsensitivitydependsontheexpectedcurrentvalue.Asaprecaution,
alwaysstartwiththelowestsensitivity,x1/10,andincreaseitasneeded.

2.3.2 Making a Measurement (Resistance of Legs)
1. PlaceauxiliaryelectrodesH (Z) and S (Y)onoppositesidesofthetower,as
farawayaspossible(100-150ft)and,ifpossible,perpendiculartothehigh-
voltageline(depthisnotimportant).Thiswilleliminateinterferencewiththe
measurementbystrayvoltages or currents induced under the high-voltage
line.
NOTE: The H (Z) and S (Y) electrodes can be placed in the same direction
if necessary. In this case, the S (Y) electrode should be placed at 62% the
distance of H (Z).
2. In order to avoid electromagnetic interference, it is best to unwind the full
lengthofeachcablefromthereel,tokeepthecablesasfarapartaspossible
ontheground,takingcarenottoformloops,andtoavoidplacingthecables
nearorparalleltometallicconductors(cables,rails,fences,etc.).E󰀨ectsof
interferencearemeasuredinmilli-ohms.
3. Connecttheseauxiliaryelectrodes to the terminals H (Z) and S (Y) onthe
Model6472'sfrontpanel.
4. Important: TheterminalsES (Xv) and E (X)mustbeconnectedtoaconduct-
ingmetallicpartofthetowerlocatedabovetheGroundFlex®sensors.This
ensuresmeasurementofthecurrentowingdownwardandtowardstheearth
(otherwise,youwouldmeasurethecurrentowingupward,fromtheearthto
thetopofthetower).
Thiswilltelltheconditionoftheoverheadgroundconductor.
5. Connect the required number of GroundFlex® sensors to channels 1, 2, 3,
and/or4(thechannelsforwhichtheyarecalibrated)andplacetheGround-
Flex®sensorsaroundthelegsofthetower.
NOTE: The direction of coiling of the sensors around tower legs have no
effect on the measurement, but all of the GroundFlex®sensors must be
coiled in the same direction and have the same orientation (check arrow
direction on the sensor) and they must all have the same number of turns.
Sensors should encircle both leg AND ground system.

2.3.3 Other Measurements
AsexplainedinStep4onthepreviouspage,terminalsES (Xv) and E (X)mustbe
connectedtoametallicpartofthetowerabovetheGroundFlex®sensor in order to
measurethecurrentowingISELdownwardthroughthesensortowardstheearth
tomeasuregroundresistanceoftheleg.
IfconnectionsES (Xv) and E (X)areplacedbelowtheGroundFlex®sensor,the
lattermeasuresthecurrentowingtowardsthetopofthetowerviatheoverhead
groundconductoratitstop,andyoucaninthiswayevaluatethequality of this
overhead ground conductor.
YoucanevenmakethismeasurementwithoutmovingthecontactsofES (Xv) and
E (X) onthetowerbysimplypassingthe2connectingcablesthroughtheGround-
Flex®sensor.ThecurrentinconnectingcableE(X) andthecurrentthroughtheleg
ofthetowerthencanceleachotherout.
Youcanalsomeasureany leakage currents(I-Act)owingthrougheachlegof
thetowerinnormaloperationofthehigh-voltageline.Ifyounddi󰀨erentleakage
currentsineachleg,buttheycanceloutwhenaddedtogether,youcanconclude
thatthesecurrents,inducedbytherotatingeldofthehigh-voltagelines,indicate
an earthing faultofthetowervia the overhead ground wire at the tip of the
mast.
2.4 MANUAL Mode and SWEEP Mode
Use the Hz/OPTIONS button and ► button to change to MANUAL mode. The
followingparameterscanbemodied:
• 128Hzblinks Changethetestfrequency
• Testvoltageblinks Switchbetween16and32V
Youcanalsoperformafrequencysweepandasmoothing.

Inthesweepmode,themeasurementscanbemadeatfrequenciesupto5kHz.
Onasingletower,frequenciesintheorderof5kHzdonotalwaysentailinductive

Theintrinsicerrorspecied refers to reference conditions with atestvoltageof
32V,testfrequencyof128Hz,RH,andRS=1kΩ,noexternalvoltage.

TheoperatingerrorofACresistancemeasurementscanbelessthanthatspecied
forvoltageorcurrentbecausefrequencycharacteristicsofthevoltagechannelare

S x 1 ISEL > 5mA ± (5% + 4cts)

(1): Valid only in the SENSITIVITY x 10 setting
ThecurrentmeasureddependsonthenumberofturnsoftheGroundFlex®sensor
aroundtheconductortobemeasured.(e.g.if the GroundFlex®sensor is wrapped
4 times around a conductor carrying a current of 1A, the input signal will be the
same as if the GroundFlex®sensor were wrapped once around a conductor car-
rying a current of 4A. The operating error is therefore indicated for an input signal
current in A.tr (Ampere.turns).
TheminimumcurrentmeasureddependsonthesettingoftheSENSITIVITYswitch
asindicatedbythetablebelow:
SENSITIVITY IMIN (A.tr) Points additional error (pt-er)
