The Picoammeter is designed to measure very small currents and has 9 ranges from 100pA to 1µA which can be selected using the rotary switch on the front of the instrument. The instrument has a large moving coil meter with an auto-zero facility. Input is by way of 4mm sockets or a BNC socket for very low currents where a screened lead is preferred. Voltages up to 5kV will not damage the unit.The instrument is housed in the Unilab Spacesaver case.The mains cord is kept tidy by means of the cable retainer on the back of the unit which allows the cable to be stowed away neatly with the use of winding hooks and a clip to secure the cable.Suggested uses include: measurement of ionisation currents reverse currents of silicon diodes resistivity of insulators capacity leakage of currents and more.Large illuminated analogue meterDetects current as small as pAInput Resistance of 10MO and maximum voltage input of 5kVInput via 4mm shrouded sockets or BNC connector for screened leadsAuto-zero facilityThis device is compliant to EN61010-2010 with certificates available on requestDimensions:Width: 175mm.Depth: 190mm (including cable clips: 206mm)Height: 298mmMass: 2.7kg.
