Apex temp probe problems!

[Tikosyn]

My temperature probe is really acting strange lately. It currently says my tank is 82.7 degrees but a thermapen I have says my tank is 74. I don't know what to believe right now and am started to freak out a bit because these are two extremes. What do i believe? I have purchased another temp probe but obviously it won't be here for at least 4-5 days. The tank is located in the basement and the AC has been on and off running for the past few days, it is not hot down here.

Not sure if you have one of these, but it's my gold star standard that I use for calibrating all other electronic probes etc.. So far it's served me very well.

Long Stem Calibration Thermometer

Why Does BRS Recommend This? The exact thermometer we use to calibrate our temperature probes, heaters and any other device that requires calibration. We will usually double check calibration with the VWR Thermometer about once a month, and you may be surprised what you find with your probes or...

Trust the thermapen as long as it still is within calibration (ambient air or the ice test). Double check your probe wires are away from power wires and definitely not running parallel.

For next time have more than one temp sensor on the system if possible. That way you have a backup and with your thermapen you will have three readings. Two should be close. Go with the two that are close when there is a error in one.

Did you install the latest update last week? I received 2 updates last week. The first caused my temp probe to read off and then the 2nd update fixed it.
