10. Taskand AsCal
10.1 What is the AsCal?
AsCal is a typical calibration process including as‐found and as‐left, and Task is the calibration procedure of a UUT (Unit
Under Test).
The ADT22XA calibrators can perform AsCal, calculate errors (Zero Error and Span Error), display results in the memory
and highlight the out‐of‐tolerance points.
You can download tasks and upload the results with special software. The software can generate reports and
certificates for the tasks.
AsCal will make your calibration faster and easier!
As Found Calibration
The As Found calibration documents the state of the instrument before carrying out any adjustments. The calibration
shows the instrument’s level of drift during calibration
As Left Calibration
After routine maintenance and deficiencies detected during calibration are addressed, an "as‐left" calibration is
performed. Figure 10.1 gives anoverview of the AsCal calibration.
