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.
