Product Details

RS Pro RM-804/805 Series High Precision Programmable DC Milli-ohm Meters

RS Pro RM-804/805 Series DC milli-ohm meter models offer Handler, RS-232C and USB device interfaces (RM-804, 122-5158 ) plus option 01 GPIB (RM-804-01, 122-5157 ) or standard GPIB (RM-805, 122-5156 ). Model RM-805 also offers drive modes DC+/DC-, Pulsed, PWM, Zero, for measurement applications on different materials. Pulsed current output mode reduces thermal EMF influence. DC+ and DC- output modes are best for measuring inductive components. PWM output mode, ideal for temperature-sensitive materials, can avoid resistance value variation due to overload on current measurement over time. Model RM-805 also offers dry circuit which can limit applied voltage, under the open circuit voltage of 20 mV, to avoid over voltage occurring on both ends of components. RS Pro RM-804/805 Series provides a D-sub 25-pin combined interface to connect Handler, Scan or EXT IO to a sorting machine, connect with an external on-off switch and enable external trigger control. Reading resolution will not be changed by changing reading speed of the instrument - the display digits remain the same.
