Step calibration.
8.1 Ice Point preparation point temperature 0 º C
to 0 º C before check calibration.
1. Water ice clean.
2. The ice is crushed and must not be hand or objects with chemical additives are to be touched.
3. The water ice and put in place the prepared.
4. Water may cool down in about 1 in 3 parts (watch the ice is translucent color.)
5. Enter SPRT and Digital Thermometers to calibrate down.
6. When the ice has melted to drain out and put some ice again.
7. Wait about 30 minutes, we will read the temperature of ice are melting at 0.2 º C
8.2 for Bath Calibrator bring water or alcohol in Bath brought Standard PRT 2 which are calibrated to the Standard Indicator DMM Model Fluke 8846A to Fluke 1529 and Digital Thermometers used for calibration on the field of space Insert the Bath by the depth of the dip is 10 times the diameter of Digital Thermometers used for calibration .
8.3 machines run calibration.
