Like it will read 78%, but within a minute will drop down to 44% (probes are not moving). Both probes will read 44% until I clear the max/min memory. Right now I took a hygrometer out of another tank but I need a hygrometer with probe for the rack.

Anyone else have similar problems with the Accurite thermometer/hygrometer? Am I doing something wrong? Otherwise I'm going to return them and try to find a more reliable hygrometer.
The acurites don't read humidity through the probe, only through the unit itself.
