Correction calculation
The theoretical melting point is stated for the reference
substance. If an interval is given, the mid-point is the theoretical
melting point.
Correction = Theoretical melting point display
Examples:
• The theoretical melting point of vanillin is 83.0°C. The Büchi
Melting Point B-540 found a melting point of 82.3°C.
Correction: 83.0°C = +0.7°C
• The theoretical melting point of vanillin is 83.0°C. The Büchi
Melting Point B-540 found a melting point of 83.0°C.
Correction: 83°C = -0.3°C
Now the pertinent corrections can be entered for the three
types of calibration substances. The left column indicates the
last correction, the right column is used to enter the new
corrective value.
By pressing the UP/DOWN/NEXT keys, the necessary
corrective value at 83°C is entered.
By pressing the ENTER key, change to the 2nd temperature
value and adapt this analogously.
Then press the ENTER key to change to the 3rd temperature
value and adapt this analogously.
Press the ENTER key to change to the STORE CALIBRATION
field and press the UP/DOWN key to obtain YES.
By pressing the ENTER key, the new calibration is confirmed.
For reasons of safety, the user is inquired again whether the
corrective factors should be stored. If this is the case, set the
display to YES and confirm with the ENTER key.
Checking of the calibration with the same parameters under
the recommendation (see above).
