i have a zt2 wideband with lcd display and everytime i check the peak values its gotten they are always richer than anything ive logged with evoscan.
so which one is the truth? anyone ever have this issue? should i trust my zt2 logger or evoscan?

 

I have a ZT2 and have never really noticed any difference. I mean a 0.01 difference isn't a hill of beans. If it were off by like a full point, then I would be worried.

 

I just use evoscan, but I don't have the display.

 

If you talk to Ziggy at Zeitronix he will readily tell you that the LCD display doesn't update as fast as ZDL or the analog output and makes for "lag" to the naked eye and to go by the value in the ZDL data logger. The fact that the peak values aren't the same is definitely an issue though. I would just send an email and see what he says.

 

well i know its a bit slower but the display has peak hold button and when i check that ive gotten say a 10.2 then i check my log and the lowest number anywhere on it is a 10.6
