Operating Modes

The ADS1x31REF operates in one of three modes:

•

Scale mode: When the mode select switch is in Scale position, the ADS1x31REF acts as a basic

weigh scale. The scale has tare, range, and calibrate functions, and can display metric (SI) units. Other

parameters can be configured in configuration screens. Scale mode is described in detail in Section 2.

•

Analysis mode: When the mode select switch is in Analysis position, codes are taken directly from the

installed ADS device and various measurements are made upon them. Several measurements are

available, including raw display, voltage, RMS noise, and peak-to-peak measurements. The ADS1131

or ADS1231 can also be configured directly from this mode. Analysis mode is described in detail in

Section 3.

•

Configuration mode: Parameters governing the operation of the ADS1x31REF can be viewed and

altered in this mode. Scale and Analysis modes have different options in configuration mode:

configuration for Scale mode is described in Section 2.4, and configuration for Analysis mode is

described in Section 3.4.
