High-precision digital multimeters have many functions, are highly accurate and easy to automate systems, and can easily replace zero detectors, etc. However, their DC input amplifiers do not have the specific design required to fully match the characteristics of zero detectors. High-precision digital multimeters are deficient in some key respects. One of the key issues is the instrument's input bias current. The latest Fluke high-precision digital multimeter 8588A has a significantly smaller bias current, with a maximum of only 20pA. The bias current can also be adjusted almost to 0pA. And as time changes, the bias current changes very little, ensuring that the Fluke 8588A high-precision digital multimeter is a suitable product to replace the analog zero detector.
