I purchased a Herpstat 2 and set up an individual tub with it. I set the probe between the top of the 11" flex watt and the bottom of the tub; according to the probe reading on the Herpstat it is 100.6 yet the floor of the tub reads 85 with a temp gun. I was looking on Spyder's troubleshooting and they made it sound like that the probe should be inside the animals enclosure. I have always placed the probe between the flex watt and the tub. Is this right? and do I need to adjust the probe sensitivity? Thank you for taking the time to read this an hopefully respond.
