Applications
The CPA2501 is used in aviation and aerospace applications for calibration of altimeters and airspeed indicators, displaying altitude, airspeed, altitude rate (vertical airspeed) and airspeed rate (acceleration). Applied wherever there is a need for a high level of accuracy in an avionics indicator or calibration device.

Functional Flexibility
The CPA2501 can be configured with an altitude channel and an airspeed channel consisting of Ps / Pt or Ps / Qc. It can be configured as a single channel altitude / altitude rate indicator, (Ps only) a single channel airspeed / airspeed rate indicator (Qc only) or it can be a dual channel unit configured as Ps / Pt or Ps / Qc. In the Ps / Pt version the airspeed / airspeed rate channel is a calculated channel. An optional barometer can be installed for display in the front panel or as a separate channel. Pressure ranges for each channel can be specified by the customer. Guidelines for ranges are given in the pressure range section of the specifications on page 2.

Versions
The CPA2501 versions are as follows:

• Ps (altitude version)
• Qc (airspeed version)
• Ps/Qc with a virtual Pt channel
• Ps/Pt with a virtual Qc channel

An optional barometric sensor can be added to any version.

Communications
The manual user interface is through a wide screen display with touchscreen. Navigation within the intuitive menu structure is easily learned. Recognizable icons, when touched, open screens for configuration and calibration. Communicating to a remote computer is achieved through Ethernet, RS-232 or optional IEEE-488 communications. Commands used for communication are the same as the previous version of Mensor avionics gauge models 2108 and 2109 or the WIKA SCPI command set.
