6.6.1 Media compatibility
CAUTION!
The calibrator should only be used with clean, dry gases! To prevent contamination by
the test pieces, the use of a dirt trap is recommended (see chapter "10. Accessories")!
6.6.2 Measuring pressure with external modules
The calibrator has a digital interface for external pressure modules. These modules are available
for various ranges, including gauge, vacuum, differential and absolute pressure. The modules work
seamlessly in conjunction with the calibrator. Simply plug them into the interface and select [EXT]
(external sensor). Since the interface between the calibrator and the module is digital, the accuracy
and display resolution is dependent on the module.
