Figure 3-17 D3 or D3-and-D4 density calibration – ProLink II
3.8 Performing temperature calibration
Temperature calibration is a two-point procedure: temperature offset calibration and temperature
slope calibration. The entire procedure must be completed without interruption.
To perform a temperature calibration, you must use ProLink II. Refer to the menu flowchart in
Figure 3-18.
