I think you&#39;re saying that actually there&#39;s no need to go into an AC mode if you have the TPR1000, since you can null out up to +-60V offset, i.e. that infers that you&#39;ll get flat response all the way down to DC. So the chart and table do not apply. Is my understanding correct?</p><img src="https://community.element14.com/aggbug?PostID=28315&AppID=44&AppType=Weblog&ContentType=0" width="1" height="1">
