Barometric Pressure/Altitude Metering; Thermometer Calibration - Vertex Standard Pilot VXA-210 Operating Manual

Thermometer Calibration

r Press the [ F ] key, then press the DIAL selector
knob to activate the Menu ("SET") mode.
r Rotate the DIAL selector knob to select Menu
Item 14 "TEMP."
r Press the DIAL selector knob to enable adjust-
ment of this Menu item.
r Rotate the DIAL selector knob to set the differ-
ence (value: in °C) between the VXA-210 dis-
play and the calibrated thermometer. For ex-
ample, if the VXA-210 display shows "24.5 C"
and the thermometer (wrongly) indicates "24.0
°C," set the TEMP offset to " – 005".
r Press the DIAL selector knob to save the new
setting, and then press the PTT key exit to nor-
mal operation.
The optional SU-1 Barometric Pressure Unit for the VXA-210 measures pressure in the immediate vicinity
of the transceiver. When using the VXA-210 equipped with the SU-1 in a pressurized cabin of an aircraft,
of course, the VXA-210 will not be able to measure outside temperature and pressure, nor display altitude
accurately.
Please rely on your aircraft's altimeter for such data.

LTITUDE ETERING
The optional Barometric Pressure Unit (SU-1) brings
to the VXA-210 the unique capability of providing
readout of the current barometric pressure. This in-
formation is the used for calculation of your current
altitude, and also used for calculation of your cur-
rent density Altitude using with the temperature sen-
sor.
The Barometric Pressure unit and temperature sen-
sor requires calibration of the "offset" parameters,
so that differences in pressure can be used to calcu-
late altitude. This procedure requires that you have a
calibrated barometer, calibrated thermometer, and
that you know your current altitude. If you are at sea
level, of course, the latter parameter requires no re-
search.
