儀器介紹
The Fluke 8845A 6.5 digit precision multimeter has the precision and versatility to handle your most demanding measurements on the bench or in a system. Wide Measurement Ranges: Resistance or current has been extended to cover the widest range possible. The 8845A ranges from 100 µAmp to 10 Amp with a maximum resolution of 100 pico Amps. Perform 4-wire measurements easily with two leads: Patented split terminal jacks for 2x4 Ohms function allow you to perform precise 4-wire measurements with only two leads instead of four. Optional Kelvin leads accessories are available to enable you to establish a 4-wire connection even in tight spaces.
