Measurementcategories(Over-voltagecategories)
Toensuresafeoperationofmeasuringinstruments,IEC61010establishessafety
standards for various electrical environments, categorized as O to CAT IV, and
calledmeasurementcategories.
Higher-numbered categories correspond to electrical environments with greater
momentary energy, so a measuring instrument designed for CAT III environments
canenduregreatermomentaryenergythanonedesignedforCATII.
O: Circuitswhicharenotdirectlyconnectedtothemainspowersupply.
CATII: Primary electrical circuits of equipment connectedto an AC electrical
CATIII: Primary electrical circuits of the equipment connected directly to the

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"
markshowing, battery voltageis OK.Ifthe displayblanks or"BATT"is
indicated, replace the batteries according to section 8: Battery
