Introduction
The ASV-2 is a 3 1/8" sunlight readable encoding altimeter, airspeed and wide range vertical speed indicator.
The altimeter contains an internal high accuracy 24 bit digital altitude sensor which calculates altitude from -1000 ft up to
a maximum of 35000 ft. The ASV-2 outputs various formatted RS232 serial data protocols compatible with serial input
transponders such as that from Garmin, Magellan, Northstar, Trimble, Microair etc. The altimeter can display altitude in
feet or meters and local pressure can be set in millibars or inches of mercury
The VSI indicator can be displayed in either feet/minute (ft/min) or meters/second (m/s). The VSI can be calibrated by the
user once the instrument has been installed in the aircraft.
Airspeed is based on the pressure generated by a pitot tube system and a static port is provided as well for use by high
speed aircraft. The ASV-2 instrument measures airspeed from 16mph to 250mph and is well suited to slower aircraft due
to very good sensitivity and linearity at low air speeds. Airspeed can be indicated in statute miles per hour (mph),
kilometers per hour (km/h) or nautical miles per hour (kts). The ASV-2 also provides a programmable Vs and Vne
airspeed alarm output. ASI sensitivity can be calibrated by the user to cater for errors caused by pitot tube placement.
In addition, the ASV-2 provides an encoder test function, flight timer since takeoff and records the maximum airspeed
reached. The ASV-2 provides a parallel Gillham code interface when used in conjunction with the MGL Avionics CNV-
ALT.

  • Page 9 Blaze ASV-2 Operating Manual Page 9 4.4 ASI Setup (Airspeed Setup) Zero ASI Sensor: This setup allows your instrument to measure the zero airspeed reading of the airspeed sensor and set a calibration value internally for this. This is equivalent to some mechanical airspeed indicators that have an adjustment to set the needle to zero when the aircraft is not moving.

  • Page 16: Installation

    Blaze ASV-2 Operating Manual Page 16 10 Installation Connect a pitot tube to the “pressure port” and if required connect the static port. Connect the static port to a suitable static air pressure line. If you have a slow aircraft or an aircraft where the internal cabin pressure does not change during flight and is equivalent to the outside air pressure you may find that it is not required to connect a static port.
