Measurementcategories(Over-voltagecategories)
Toensuresafeoperationofmeasuringinstruments,IEC61010establishessafety
standards for various electricalenvironments, categorized as O toCAT IV, and
calledmeasurementcategories.
Higher-numbered categories correspond to electrical environmentswith greater
momentary energy,soameasuring instrumentdesigned for CATIIIenvironments
canenduregreatermomentaryenergythanonedesignedforCATII.
O: Circuitswhicharenotdirectlyconnectedtothemainspowersupply.
CATII: Primary electrical circuitsof equipmentconnectedto anACelectrical
outletbyapowercord.
CATIII: Primary electrical circuitsof the equipment connected directlyto the
distributionpanel,andfeedersfromthedistributionpaneltooutlets.
CATIV: The circuit fromthe service drop to the service entrance, and to the
power meter and primary overcurrent protection device (distribution
panel).

5-1 Checking Battery Voltage
Set the Range Selector Switch to any position other than the OFF
position. If the marks on the display is clearly visible without "BATT"
mark showing, batteryvoltageis OK.If thedisplayblanks or "BATT"is
indicated, replace the batteries according to section 8: Battery
Replacement.
