@Bill Kielb that was it! Thank you. I haven't had to change one in years so I thought I was doing the installation wrong. Nope it came hooked up wrong. Thanks again!

no it is in my closet across from my classroom. I can't find anything online about what the lo means but that is the only thing that is on the screen.

My old, old kilns pyrometer broke so I was told the dual input pyrometer and thermometer would still work in my kiln. I went to try it out and do a test firing but when I click it on it says lo on the screen. I changed the battery when it came in last week because the battery was dead. Any help is greatly appreciated. Thanks
