ProbeZERO/ Delete Log Key

Before being used, differential pressure gauges and Pitot tube or hot-wire air speed probes need to
be set to zero. The key Probe ZERO has this function: for details on how it works, see the chapters
concerning the different probes.
The secondary function of this key is to clear the whole memory content (press PROG >> Probe
ZERO – DEL LOG is viewed >> press ENTER to confirm).
In order to know which is the available memory space, press PROG and then CALL: the number of
available pages will appear – from 1 to 1999 -; ALL means that the whole memory space is
available (2000 pages). .
