BESKRIVELSE
The 1855 instrument measures and displays the undesirable flow of current through a capacitor over any surface of insulation. The 1855 Model offers flexibility with programmable charge current from 0.5mA to 500mA in increments of 0.5mA. The DC voltage can be programmed from 1.0V to 100V in 0.1V increments (with current to 500mA) and from 101V to 650V in 1V increments (with current to 150mA). The 1855 serves as an economical megohmmeter by measuring and displaying a product's insulation resistance. This resistance can be measured over the range of 10Ω to 99GΩ with a programmable test voltage from 1.0V to 650V DC.
