Caution: READ this section BEFORE PLACING THE BATH IN SERVICE

The information in this section is for general information only. It is not de- signed to be the basis for calibration laboratory procedures. Each laboratory will need to write their own specific procedures.

6.1General

Be sure to select the correct fluid for the temperature range of the calibration. Bath fluids should be selected to operate safely with adequate thermal proper- ties to meet the application requirements. Also, be aware that some fluids ex- pand and could overflow the bath if not watched. Refer to General Operation, Section8, for information specific to fluid selection and to the MSDS sheet spe- cific to the fluid selected. The temperature range of any single fluid is likely less than that of the bath itself. This means that the type of bath fluid may have to change to cover the full range of the bath (see Section8.1.1). Baths are most often set up to operate with a single fluid only over the useful range of that fluid. Other baths can be set up with other fluids to cover other temperature ranges required. This is generally the most productive and efficient approach.

The bath generates extreme temperatures. Precautions must be taken to prevent personal injury or damage to objects. Probes may be extremely hot or cold when removed from the bath. Cautiously handle probes to prevent personal in- jury. Carefully place probes on a heat/cold resistant surface or rack until they are at room temperature. It is advisable to wipe the probe with a clean soft cloth or paper towel before inserting it into another bath. This prevents the mixing of fluids from one bath to another. Always be sure that the probe is completely dry before inserting it into a hot fluid. Some of the high temperature fluids react violently to water or other liquid mediums. Be aware that cleaning the probe can be dangerous if the probe has not cooled to room temperature.

For optimum accuracy and stability, allow the bath adequate stabilization time after reaching the set-point temperature.

6.2Comparison Calibration

Comparison calibration involves testing a probe (unit under test, UUT) against a reference probe. After inserting the probes to be calibrated into the bath, al- low sufficient time for the probes to settle and the temperature of the bath to stabilize.

One of the significant dividends of using a bath rather than a dry-well to cali- brate multiple probes is that the probes do not need to be identical in construc-
