测量精度
A patented rectifier circuit with microprocess-controlled autocalibration makes f the outstanding measurement characteristics of URE2URE3. In der to further enhance the accuracy, crection facts are determined f each instrumentmeasurement rangested in a nonvolatile memy.
A zero function allows noise voltagesthe inherent noise to be compensated f, the measurement accuracy being thus increased in particular at low levels.
The measured frequency value is used by URE3 f an internal frequency response crection. This method increases the accuracy mainly at the higher frequencies. Disttion-free measurement of signals is ensured by:
·high input impedance
·low input capacitance
·highpasslowpass filters that can be switched in to suppress hum high-frequency
·noise voltages
