eCAL™ Software Application
Calibration protocols. Quick. Easy.
The eCal™ software application has been specially developed by SPEKTRA for calibration laboratories. eCalTM is simultaneously a universal calibration protocol viewer and a data transformation tool.
The application can transfer calibration data from various programs such as the SPEKTRA CS18 or CS Q-LEAPTM calibration systems into standardized output formats for digital distribution or printing. One dataset can therefore be used to generate calibration certificates in print form as well as digital calibration certificates, or to provide data for further processing in databases – all with the same ease. Further modules will be added to eCalTM in the future to allow post-processing of documents (signing, release, document storage, etc.) and workflows.
eCal™ – Calibration tasks made easy
- Read calibration data from a variety of input sources
- Represent calibration data in an internal, extendable data format
- Load multiple calibration protocol files with one click
- Templates for a concise display of calibration data in diagrams and tables
- Enables editing of order data without affecting the measurement data
