HM inline tds meter going wack

[Spare time]

After putting in new di resin, my meter reads 0tds going into the resin (normally is 3). The output value jumps up and down from single digits into the teens every second. Did my meter just crap out?

Make sure the probe is properly inserted into the T.

Water should flow between the prongs.

You can totally remove it and test it in various fluids if you think it may be bed.
