Launching the calibration function
The following diagrams show the sequence of a user calibration in SIMATIC PDM V6.0 +
SP5. More recent versions of SIMATIC PDM can deviate from the content of these
diagrams.
The module calibration function is launched in the SIMATIC PDM via <Device ⇒ Calibration>
for the selected module.
Figure 6-37
Once the calibration function has been launched, the calibration start screen appears. Each
time a new channel is selected, the module reads the following general data and calibration
values:
General data:
● Measuring range: Currently programmed measuring range for the selected channel
● Date: Date and time when the displayed calibration values were determined
● Calibration: Indicates whether the currently active calibration values are factory-set or
user values
