Reply to ""Adjusting" water temp gauge"

If you want to take the time to "dial it in", install a variable resistor first, 0-50 ohms or 0-100 ohms, bring it up to temp, use the IR gun and adjust the variable resistor (potentiometer) to get the right reading. Measure the setting with an ohm meter and install the right resistance value/values to match. I had to put two in parallel to get the right value.
