Temperature offset
There is a temperature offset function on the Innova 40/40R Shaker that allow you to match a reference
point temperature inside the chamber with the actual value displayed. The actual value displayed may not
equal the temperature at different points of the shaker chamber due to many variables.
If you wish to have the actual value displayed on the shaker match a diffferent point of the chamber, you
must:
1. Calculate the temperature offset desired.
2. Create the temperature offset in the
CAL
screen.
5.10.2
Calculating the temperature offset
In the
CAL
screen:
1. Allow the shaker enough time to equilibrate to setpoint temperature.
2. Record the displayed setpoint temperature (
temp1).
3. Record the temperature inside the chamber (
temp2). You may record the temperature inside a flask or
at any point inside the temperature.
4. Use the formula:
temp2 - temp1 = °C
