I have a 5 month old Hanna alkalinity checker that stopped working 2 days ago. When I put the cuvette with the plain tank water and push the button, I get the 3 blinking lines, but they last for almost a minute. Then I get the L.Lo error. I tried with tank water, new salt water, and RODI water with the same result. I wiped the cuvette with a lint free towel, gently cleaned the inside of the tester, and replaced the battery. Everything worked fine before 2 days ago.
Any idea of what’s going on? Thanks!
