Introduction This technical supplement has been written to amplify the recommendations given in WHO Technical Report Series No. Sometimes a dial stem thermometer loses calibration (it no longer registers temperature correctly). If the body temperature is above 100°F (38.7°C) you will hear one long beep followed by three short beeps and a sad face will appear on the display. Digital Thermometers. Use a standard thermometer to calculate the input signal compensation for the ambient temperature. See manufacturer's instruction guide. Thermometer calibration means checking that your thermometer is working correctly, and making adjustments if it is not. 3. Return device to station for unlocking. Be sure to dry thermometer thoroughly before store in the case provided with the unit. However, the inaccuracy can be added or subtracted to the final desired cooking temperature and the thermometer should be checked regularly. Barbara. Soluble solids are measured by a refractometer and expressed as degrees Brix which is equivalent to the percentage by weight of sugar. 4. for State Calibration Laboratories Program Objective This publication provides guidelines for evaluating data from advanced mass calibrations and for establishing measurement assurance programs in precision mass calibration laboratories.
