To use this function, you also need to set up the polar curve of your glider.

THERMAL SNIFFER
To utilize the thermal sniffer function, you must have an air
speed probe connected. The optional air speed probe should be
plugged in to the right hand socket on the bottom of the vario.
If this parameter (ADVANCED SETUP \ n. 8 POLA) is set to “OFF”, all display information
relating to McCready, McCready Equivalent, Thermal Sniffer is not displayed on the
instrument, creating a cleaner display for users not needing this functionality.
The thermal sniffer is an innovative function that helps you to detect a thermal early.
It alerts you with a sound and the popup message “THERMAL” when you are in a thermal
but your vario is still indicating sink because your sink rate is higher than the speed of
the rising air.
This function uses two parameters, the thermal strength and the time over which the
themal must occur.
To set the thermal detection parameters, go to (ADVANCED SETUP \ n. 2 THEV) and
(ADVANCED SETUP \ n. 3 THET) to adjust the time over which a change in height is
required for detection of a thermal.
To use this function you need to set up the polar of your glider.

THERMAL CENTERING FUNCTION
This is a live plot of your vario against time, it scrolls whilst you are flying. It will help you
to see how wide the thermal is and how far you flew from the best lift you encountered. It
is especially useful in weak conditions.
To switch between the Thermal Centering Function and the Graphic Altimeter press the
key (long pressure).
The horizontal (x) scale, time (in minutes) can be changed, go to (MAIN SETUP \ n. 13
BARX).
