To read temperature...
The temperature sender (the sensor that sends the temperature signal to the gauge) has to be immersed in coolant in order to correctly read the temperature. If the coolant is so low that it leaves the sender high and dry, the temperature shown on the gauge will not be a true reading. if the sensor is not immersed in the coolant, there a big chance it wont read at all...

scientist use a thermometer to read temperature
At a temperature of -40 (minus forty) degrees, the Celsius and Fahrenheit scales read the same number.
To read a thermometer accurately, first make sure it is clean and at room temperature. Hold it at eye level and read the temperature where the liquid inside the thermometer stops moving. Take note of the temperature markings and any numbers on the scale to determine the accurate reading.
No some read the temperature as Celsius, some as Fahrenheit, some as Kalvin
Usually around 220.
A thermometer is read by looking at the level where the liquid inside the tube stops rising. This level corresponds to the temperature measurement indicated on the scale of the thermometer. The temperature can be read in degrees Celsius or Fahrenheit depending on the type of thermometer.
Normal operating temperature for your xantia is between 80 to 90.
To properly read an aquarium thermometer for accurate temperature monitoring, first ensure the thermometer is placed at the water level and not touching any surfaces. Read the temperature indicated on the scale, which is typically in degrees Celsius or Fahrenheit. Make sure to check the thermometer regularly to track any fluctuations in temperature that may affect the health of your aquatic pets.
