When using the ice-point method to calibrate a thermometer, first ensure that you have a mixture of ice and water at 0°C. Immerse the thermometer's sensing element in the mixture, ensuring it does not touch the container's sides or bottom. Allow the thermometer to stabilize for a few minutes, then read the temperature and adjust the thermometer as needed to ensure it accurately reads 0°C. Finally, document the calibration results for future reference.
When using the ice point method to calibrate a thermometer, you should first ensure that the thermometer is clean and free of any contaminants. Next, immerse the thermometer's probe in a mixture of ice and water, ensuring that the probe does not touch the sides or bottom of the container. Allow the thermometer to stabilize for a few minutes, then check the reading; it should be at or very near 0°C (32°F). If necessary, adjust the thermometer according to the manufacturer's calibration instructions.
The thermometer will show the temperature of the pure water being collected, which should be around the normal room temperature. If the water was heated or cooled prior to collection, the thermometer will reflect that temperature instead.
One should have a standard certified temperature calibrator system before attempting to calibrate a temp. transmitter. I believe you want to calibrate the temperature sensor connected to a transmitter and to an indicator. There are three things in all. Temp. sensor it could be RTD or TC. Temp transmitter which transmits the sensor input to the indicator on which one can read the temperature. All three can be calibrated separately or together. If together it can be called loop check. Now to calibrate the transmitter know the range the transmitter and the output signal it is designed for. Say it is designed for 4-20 mAmp signal output and the range is 50'C to 200'C. It means the transmitter is supposed to give 4 ma output when it is measuring 50 'C and 20 ma when it is measuring 200 'C and be liner through out the range. Connect the transmitter to standard 4-20 ma meter. connect the standard resistance equivalent of 50'C in steps of 50'C. Measure the map signal with each step of 50'C equivalent of resistance connected. with increase in step the mamp must increase correspondingly linearly upto 200'C on the meter. Repeat the same in decreasing order in steps from 200'c to 50'C and measure the mamp. Adjust the potentiometer if any on the transmitter in case of deviation. Let the transmitter be with in its defined permissible error range while adjusting the transmitter
The temperature reading for a bimetallic thermometer when calibrating in an ice water bath should be 0 degrees Celsius (32 degrees Fahrenheit). This is because ice water has a defined temperature of 0 degrees Celsius, which is used as a reference point for calibration.
To calibrate a freezer thermometer, you will need a glass of ice water. Place the thermometer in the ice water for a few minutes, making sure it does not touch the sides or bottom of the glass. The thermometer should read 32°F (0°C) in the ice water. If it does not, adjust the calibration nut or dial on the thermometer until it reads the correct temperature.
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.

When using a Fahrenheit thermometer, temperature should be measured to the nearest degree.
The thermometer should be kept upright not tilted. 2.) The bulb of the thermometer should be surrounded from all sides by the substance of which the temperature is to be measured. 3.) The bulb should no touch the surface of the container.
You should place the thermometer under your tongue for an accurate oral temperature reading.
Meat thermometer.
If you hold the bulb end, the thermometer will measure YOUR temperature instead of the temperature of the medium that you wish to measure.

A meat thermometer should be left in the oven for about 10-15 seconds to ensure accurate temperature readings.
