I just did this. They are 0-90 ohms. Mine test from like 1 to 91 ohms.

From my experience, the flag is set based on your IP address. Are you connecting to the internet through a VPN? Its server may be based in Canada.

As Melbo says, use an ohm meter from sensor ground to the sensor connector and read the resistance.

My Staff says I never listen to them, or something like that
 
VPN - virtual private network. Read about it on wiki.

No telling where your provider's servers are physically located on the net by IP asignment.

I use alligator clips on my meter and connect to the stud on the top of the unit and clip the other one on any metal part BUT to be sure the ground
wire is good it would be best to connect to the black ground wire attached to the unit. Then just move the float up and down and watch the numbers on
the meter.

0-90 is typical GM. Best to have meter in a manual mode probably 200 Ohm scale. Watch for dropouts./ deadspots. This is actually a great use for an
old school analogue meter.

Perhaps Texas is quietly negotiating an exit from the US and joining up with Canada? :)
