4.10 Probe Alerts

Figure 4.13: Probe Alerts

The VARIO SD allows relating alerts with some probes values (see Figure

4.13

). A short description of

each alert is sown in Table

4.4

Table 4.4: Probe Alerts

Alert

Description

Pulse Threshold

Pulse Threshold above which the pulse data eld will toggle be-

tween inverted numerical display and normal numerical display.

This allows the user to quickly see that they have a pulse above

the desired level..

Stall

IAS speed value starting which a alarm is triggered (TAS Probe

needed).

4.11 Calibration

All models of the new Flymaster SD series include a magnetometer and accelerometer sensor. Using these

sensors the VARIO SD can provide G-Force and magnetic compass heading. Even though the compass

is digital there is a tilt compensation algorithm that ensures accurate compass heading even when the

VARIO SD is inclined.

The Calibration menu option allows the user to calibrate the VARIO SD accelerometer and magnetometer

sensors. Calibration is particularly important for the magnetometer since without it you will get inaccurate

data from the compass. Despite all Flymaster instruments being factory calibrated errors can be introduced

due to several external inuences, such as the presence of strong magnetic elds or the time. In order

to eliminate these errors a proper magnetometer calibration should be made. Calibration parameters are

kept when the VARIO SD is turned o, reset or when a rmware update is done. The magnetometer

calibration process is described in Section

6.2

The VARIO SD magnetic compass is very sensible to external magnetic elds. In order to

get good readings ensure that there are no interference sources nearby.
