Page 6: General Information
Model DP301AN is pin compatible with newer voltmeters DP302, DP3001 and DP3002 series. Models DP301AN has a resolution of 1 part in ±1999 counts, or 0.05% of full scale. By using an external dc voltage reference, any of these ranges can be configured for 3 wire ratio measurement with readout from 0 to 1.999. -
