3. Measuring Pressure
To measure pressure, connect the calibrator using an appropriate
fitting. Choose a pressure setting for the display being used. The
calibrator is equipped with one internal sensor and many optional
external Pressure Modules are available. Be sure to choose the
sensor based on working pressures and accuracy.

Use the (ZERO) key to zero the pressure sensor when vented to
atmospheric pressure.
Important NOTE: To ensure accuracy of the calibrator it is critical
to zero the calibrator before a device is calibrated.
3.1 Media Compatibility
The calibrator utilizes a media isolated sensor to prevent sensor
contamination. Whenever possible clean, dry air is the media of
choice. If that is not always possible, make sure that the media is
compatible with Nickel Plated Brass, Silicon, RTV, glass, and ceramic
materials.
3.2 Measuring Pressure with External Modules
The calibrator provides a digital interface to External Pressure
Modules. These modules are available in various ranges and types
