INTRODUCTION

WARNING

These safety warnings are provided to ensure the safety of

personnelandproperoperationoftheinstrument.

• Thisinstrumentisprotectedfromaccidentalvoltagesofnot

more than 50V with respect to earth in measurement Cat-

egoryIII.

• Donotattempttoperformanytestswiththisinstrumentuntil

youhavereadtheusermanual.

• Tests are to be carried out on de-energized circuits only!

Never connect the unit to a live circuit.

• Make sure that none of the input terminals are connected

andthattheswitchissettoOFFbeforepluggingintheAC

and electronic equipment in accordance with WEEE directive 2002/96/EC.

1.2 Deﬁnition of Measurement Categories

CAT IV: For measurements performed at the primary electrical supply

(<1000V) such as on primary overcurrent protection devices,

ripplecontrolunits,ormeters.

CAT III: For measurements performed in the building installation at

the distribution level such as on hardwired equipment in xed

installationandcircuitbreakers.

CAT II: For measurements performed on circuits directly connected to

the electrical distribution system. Examples are measurements

onhouseholdappliancesorportabletools.

1.3 Receiving Your Shipment

Uponreceivingyourshipment,makesurethatthecontentsareconsistent

CHAPTER 2

PRODUCT FEATURES

2.1 Description

The Micro-ohmmeter Model 6240 is used to perform low resistance

measurementsfrom5μΩto 400Ω.Therearesixrangeswithtestcurrents

from10mAto10A.

Thefrontendofthemicro-ohmmeteremploysafour-wireKelvincongu-

ration,whicheliminatestestleadresistanceforameasurementaccuracy

of0.25%.Abuilt-incircuitltersoutACsignals.

TheMicro-ohmmeterModel6240ispackagedinasealedeldcasewell

suitedforshopandelduse.Powerissuppliedbyalong-lifeNiMHbattery

packwithabuilt-inrecharger(110/220V).

Thelarge,easy-to-readliquidcrystaldisplayis2.25x4.00".Itdisplaysthe

valueofresistance,currentorvoltagetest,polarityandbatterycharge.

Foroperatorsafetyandinstrumentprotection,themicro-ohmmeterisfuse

protectedattheinputs.Onefuse,accessiblefromthefrontpanel,protects

againststoredenergyininductiveloads.

Enhanced internal circuitry protects against possible inductive kickback

whenthecurrentisshuto󰀨.

Abuilt-inthermalswitchprotectsthemicro-ohmmeteragainstoverheating

onthe10Arangewhenincontinuoususe.

Micro-Ohmmeter Model 6240

• Autostoreofmultipletestresults

• Internal,rechargeablebatteriesconductupto850,10Atests

• Abuilt-inbatterypackrechargerrechargesthebatteriesby

connectingtotheACline(110V-230V,50/60Hz)usingastandard

line cord

• 4-Wiremeasurementwithautomaticcompensationof

undesirablevoltagesandleadresistance

• Largemulti-functionbacklitdisplay

• Directdisplayofthemeasurementwithunits,rangeandtest

current

• Rugged,sealedcase
