Fluke 190-202/AM/S Fluke 190 Series II Scopemeter Family Product Datasheet - Page 3

Built to withstand harsh environments with the highest safety ratings Rated all the way to CAT IV ScopeMeter test tools are rugged solutions built for industrial troubleshooting. The new Fluke 190 Series II are double-insulated floating oscilloscopes safety rated for measurements in CAT III 1000 V/CAT IV 600 V environments. Measure from mV to kV safely Independent isolated inputs allow you to make measurements in mixed circuits having different ground references reducing the risk of accidental short circuits. Conventional bench oscilloscopes without special differential probes and isolation transformers can only reference measurements to line power earth ground. With standard probes that cover a wide application range from mV to kV, you're ready for anything from microelectronics to heavy-duty higher voltage electrical applications. IP-51 rated for harsh environments Rugged and shock-proof, ScopeMeter portable oscilloscopes are built for dirty, hazardous environments. With its sealed case, it can endure dust, drips, humidity and airborne pollutants. Every time you reach for ScopeMeter you can be confident it will work reliably wherever your work takes you. Overvoltage category CAT IV CAT III CAT II CAT I In brief Examples Three-phase at • Refers to the "origin of installation," that utility connection, is, where low-voltage connection is made any outdoor to utility power conductors • Electricity meters, primary overcurrent protection equipment • Outside and service entrance, service drop from pole to building, run between meter and panel • Overhead line to detached building, underground line to well pump Three-phase distribution, including singlephase commercial lighting • Equipment in fixed installations, such as switchgear and polyphase motors • Bus and feeder in industrial plants • Feeders and short branch circuits, distribution panel devices • Lighting systems in larger buildings • Appliance outlets with short connections to service entrance Single-phase receptacle connected loads • Appliance, portable tools, and other household and similar loads • Outlet and long branch circuits - Outlets at more than 10 meters (30 feet) from CAT III source - Outlets at more that 20 meters (60 feet) from CAT IV source Electronic • Protected electronic equipment • Equipment connected to (source) circuits in which measures are taken to limit transient overvoltages to an appropriately low level • Any high-voltage, low-energy source derived from a high-winding resistance transformer, such as the high-voltage section of a copier Table 1.
