Meriam M203 Altimeter Indicated Air Speed Tester - Manual (Page 13)

ALT/ IAS (Altitude / Indicated Air Speed) Mode
The model M203 is capable of displaying altitude (feet or meters based on “U.S.
Standard Atmosphere 1962” tables) and air speed (knots, MPH or km/h). The ALT
/ IAS Mode is selected from Program Mode in the Units Select menu. Once ALT /
IAS Mode is selected, the M203’s default measurement is altitude. Pressing the
“Tare” key nulls the prevailing barometric pressure and converts the display to air
speed indication. To revert back to altitude the “Tare” key is toggled again.
To set up the M203 for ALT / IAS Mode use the following steps:
