For optimum low-level current switching up to 10 channels, the Model 7058 is designed to introduce minimal offset current error (under 1pA), while guarding ensures that high isolation (10¹⁵Ω) is maintained between input HI to input HI. Removable jumpers allow channels to be configured as voltage switches. Triaxial input connectors provide better shielding and permit direct connection to Keithley electrometers.
