Description
Leakage Current: The 1855 instrument measures and displays the undesirable flow of current through a capacitor over any surface of insulation.
Powerful Charge Current: The 1855 Model offers flexibility with programmable charge current from 0.5mA to 500mA in increments of 0.5mA.
Programmable Source Voltage: 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).
Precision Measurement: With a basic accuracy of 0.3%, the compact 1855 instrument produces consistent, stable and reliable test results.
Insulation Resistance: 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.
Aluminum Foil Withstand Voltage: The 1855 instrument meets the requirements of EIAJ RC-2364A Standard with a low programmable constant current for charging aluminum electrolytic capacitors. The rise time (Tr) and final test voltage (Vf) are shown on the instrument display.
65 Watt Discharge Circuit: Operator safety is increased with a power discharge circuit that provides rapid and complete discharge of large value capacitors.
