3) RESET OF THE “CURRENT EXTREME VALUES”
Push button: once S1
If you want to reset the “Current Extreme Value” to 0g (for example you want to measure the
extreme values of the next flight figure), you have to push S1 once. In this case, all LEDs
are lighting up for two seconds, the LC-Display is showing:
A + 0.0 g
A - 0.0 g
and the “Current Extreme Value” is reset to 0g.
On condition you push S1 for another time during this two seconds, you get to other
submenues, else the instrument returns into the “Normal Operating Mode”.
All LEDs are illuminated during the submenues.
4) DISPLAY OF THE “TOTAL EXTREME VALUES”
Push button: twice S1
Reset of the “Total Extreme Values”
Push button: twice S1 and once S2 you push S1 twice, the LC-Display shows the “Total
extreme values”. These values are the maximums of positive and negative acceleration
that occurred since the last reset of these values. They are signed with a “B” as first charac-
ter of a line, like the following example:
B + 8.4 g
B - 4.2 g
In case you want to reset these two values, you have to press S2 and the instrument sets
the “Total Extreme Values” to 0g and returns into the “Normal Operating Mode”. Provided
you pushed S1 instead of S2, the LC-Display will show the “Absolute Extreme Values”.
If there is no button pushed, the instrument will return into the “Normal Operating Mode”.
5) DISPLAY OF THE “ABSOLUTE EXTREME VALUES
push button: three times S1
Display of time and date of the “Absolute Extreme Values”
push button: three times S1 and once S2
After pushing S1 for three times, the LC-Display shows the greatest positive and the
greatest negative acceleration the instrument ever measured. These two values are stored
in the long-term memory of the instrument and signed with a “C” as first character of the LC-
Display:
C + 9.6 g
C - 8.3 g
