Multimeter  
Module  
The PX454S is a full function DMM  
suitable for use on a variety of  
platforms with the family of C&H  
carriers. This DMM is based upon a  
24 bit Sigma-Delta A/D converter  
with on-chip notch filter.  
This  
technology allows sampling  
frequencies (or filter frequencies)  
between 10 Hz and 1 KHz providing  
varying resolutions.  
The core  
measurement section is optically  
isolated and shielded.  
This unit also features a position for  
adding one single-wide M-Module.
