IT would not hurt but... The question is how much it would help.
Now a processional highly trained Operator (Not just a driver) Might (or not) know the meaning of the readings... My brother was both a Semi Owner/operator and a diesel/gasoline mechanic I'm not that good with Diesels. He likely would know what an out of range reading meant. and what the normal range is. I don't.
So the meters MIGHT be of benefit to him. NOt to me without further research and study.
Since I do not know what you know in this regard The best I can do is guess. And my guess is your knowledge of the meter readings is closer to mine than my professional operator brotehr's.
