I am using WD 10.36i, Davis VP2 + Soil/Moisture Sensors, etc.
When I am plotting the readings from my remote soil temp/moisture sensor there seems to be one channel on this graph that periodically shows positive spikes that give a reading of 9027.1 F when you move the cursor over the spike on the graph. This reading spike is only on my main #1 soil temp sensor channel. It doesn’t matter what physical sensor is plugged in (i have three) the problem is stays with the same channel not the sensor. I have swapped the sensors around and rechecked for loose connections, but it always stays with the main #1 soil temp sensor channel.
I can see there is really no such spike from the soil temp sensor data, because the Davis desktop station captures no unusual maximum readings. When I go to Averages/Extremes it shows what I would expect as the maximum soil temp for the day: for example 64.9 F. So it seems like this is a bug in the graphing software only.
Brian,
Is there any place besides the Davis Console unit where I can check the data log to see if the spikes are stored, or a graphing bug? As I noted in the original post, when I check the Davis unit for max readings for this sensor, it doesn’t have any unusual spikes in the reading or with it’s on-screen graph. The only spikes I’m seeing are on the WD graph.
David,
do you run a CA Security program by any chance?
I had spikes on my extra temp sensors, and after
I changed back to ZoneAlarm it is alright again.
