- RANGE: −1,000 to +19,990 feet or −305 to +6,093 meters. Units selectable by internal jumper plug.
- RESOLUTION: 10 feet or 1 meter.
- ACCURACY: 1% of reading ?00 feet (30 meters) over full specified operating temperature range. Meets accuracy requirements of FAA
- TSO-10B, paragraph 6.1.
- PRESSURE DISPLAY: Displays absolute ambient pressure in inches of mercury (inHg).
- POWER: 7 to 30VDC. 15 mA @ 9VDC (w/o backlight). Backlight draws additional 15 mA independent of supply voltage. A 9V battery holder is included on back of instrument.
- BATTERY LIFE: A 9V alkaline will power the instrument for over 40 hours (20 hours with backlight on continuously).
- LOW BATTERY INDICATOR: A flashing 揃AT?symbol appears when less than 2 hours of battery life remains.
- DISPLAY: 4 ?digit, high contrast, liquid crystal display with 綌 high characters. All digits and legends visibly tested on power up. Backlight for night or dusk viewing.
- DISPLAY UPDATE RATE: 0.6 seconds.
- BARO ADJ: The UP/DN switch compensates for changes in ambient, sea-level barometric pressure and can be used to set the altimeter to known field altitude or zero before flight.
- BARO ADJ. RANGE: The instrument can be zeroed at altitudes as high as 6000 feet above mean sea level and retains baro setting in nonvolatile memory.
- WEIGHT: Less than 10 oz. with 9V alkaline battery.
- DIMENSIONS: Standard 3 1/8?instrument case outline. Depth behind back face of instrument panel is 4 5/8? May be reduced to 3 7/8?by removing external battery holder.
- TEMPERATURE RANGE: Full accuracy performance from 0 to 50癈 (32 to 122癋). Degraded accuracy, but useable from −20 to +60癈 (−4 to 140癋). Temperature limiting factor is liquid crystal display.
