Emerson AMS Trex User Manual

The noise spectrum shows the highest measurement in mV (peak-to-peak) outlined in
black. Tap Reset Peak to clear the black outline and have it reset to the most recent highest
peak. For example, use Reset Peak to clear a noise spike that was detected when
connecting the Trex unit or other hardware to the fieldbus segment.
The measurements on the spectrum are also color-coded to indicate if the status of the
measurement. The colors become darker as the measurement increases.
• Green = GOOD
• Yellow = CHECK
• Orange = CHECK
Note
The spectrum measurement will fail if the noise amplitude exceeds 1.5 V (peak-to-peak). If you see
multiple high-amplitude noise peaks, look for an unattached wire that may cause high noise and
saturate the noise detection.
