6. Ambient conditions
- TheBENNINGCM9-2isintendedformakingmeasurementsindryenviron-
ment.
- Maximumbarometricelevationformakingmeasurements:2000m,
- Overvoltagecategory:IEC60664/IEC61010→300VcategoryIV;600V
category III
- Operatingclassofcurrentsensor:EN61557-13,class2,≤30A/m,@In:
3.5mAto600mA,fn:40Hzto1kHz,validinthe6/60/600mAmeasuring
range with optimal resolution
- Contaminationclass:2(EN61010-1),
- Protectionclass:IP30(DINVDE0470-1,IEC/EN60529)
 IP30means:Protectionagainstaccesstodangerouspartsandprotection
againstsolidimpuritiesofadiameter>2.5mm,(3-firstindex).Noprotec-
tionagainstwater,(0-secondindex).
- Operatingtemperatureandrelativehumidity:
 Foroperatingtemperaturesfrom-10°Cto30°C:relativeairhumiditylower
than80%,
 Foroperatingtemperaturesfrom31°Cto40°C:relativeairhumiditylower
than75%,
 Foroperatingtemperaturesfrom41°Cto50°C:relativeairhumiditylower
than45%.
- Storagetemperature:TheBENNINGCM9-2canbestoredattemperatures
between-20 °Cand +60 °C, ata relativeair humiditylower than 80%
withoutbatteries.
7. Electrical specifications
Note:Themeasuringprecisionisspeciedasthesumof
 - arelativefractionofthemeasuredvalueand
 - anumberofdigits(countingstepsoftheleastsignicantdigit).
Thisspeciedmeasuringprecisionisvalidfortemperaturesintherangefrom
23°C±5°Candrelativehumiditylessthan80%.
7.1 AC current range
Themeasuringvalueisgainedandindicatedase󰀨ectivevalue(TrueRMS,AC
coupling).Incaseofnon-sinusoidalcurves,theindicatingvaluebecomesinac-
curate.Thus,anadditionalerroroccursforthefollowingcrestfactors:
 crestfactorfrom1.0to2.0additionalerror+1.0%
 crestfactorfrom2.0to2.5additionalerror+2.5%
 crestfactorfrom2.5to3.0additionalerror+4.0%
max.crestfaktor:
 crestfaktor1.5@6000digits
 crestfaktor2.0@4500digits
 crestfaktor3.0@3000digits
Thestatedaccuracyisspeciedfor1%to100%ofthenalmeasuringrange
valueandforconductorsthatarecentrallyclampedbymeansofthemeasuring
clamp

(see gures2 to7).For conductorsthatare notcentrallyclamped,
anadditionalerrorof1%ofthedisplayvalueneedstobetakenintoaccount.
