EXTRA 300L
After resetting the “Current Extreme Values”, the LC-Display shows
A + 3.0 g
A - 0.0 g
and only the middle LED and three LEDs in the positive range of the LED-Display are
shining. If the display presents the “Total Extreme Value” you will see
A + 9.0 g
A - 5.0 g
on the LC-Display, because the “Total Extreme Values” has not changed.
The “Total Extreme Values” only change if one of them is lower than the corresponding
“Current Extreme Value” or if they are reset to 0g.
ABSOLUTE EXTREME VALUES "C"
Two further extreme acceleration values are the positive and the negative
Absolute
Extreme Value
. These values are the greatest acceleration values that ever occurred. They
can not be reset and they are stored in the long-term memory inside the instrument.
Additionally, time and date these “Absolute Extreme Values” occurred are stored. These
dates can be shown by the LC-Display by pushing the buttons.
The Output of the “Absolute Extreme Values” is signed by a “
C
” as first character of the two
LC-Display lines. The “Absolute Extreme Values” only change, if an “Instantaneous Value”
occurs that is greater than the positive “Absolute Extreme Value” or lower than the negative
“Absolute Extreme Value”.
TIME AND DATE
You can recall the current
time
and
date
by pushing the buttons. If you want to change the
current time and date of the clock, you have to enter the security code by the buttons. In
Case the code is wrong or you wait too long, the instrument will return into the “Normal
Operating Mode”. The clock module has its own battery power supply backup, preventing
the clock from stopping even in case of turning off the master switch or disconnecting the
DSA 12 from the electrical system of the aircraft.
