to an error of less than about 30 seconds per week, the message „
RTC ok!
“ is send, otherwise
the error is reported in ppm units.
The
Main battery
test allows the measurement of the lead-gel accumulator voltage and estima-
tion about its charge condition. The measurement is made in contrary to the battery test during
power on initialization without load, that means without active LED display of „188“ and can
be initiated therefore also remotely by a GSM modem. The result is given with 0,1 Volt resolu-
tion between 10,7 and 13,8 Volt (17 Ah accumulator discharge and full charge voltage levels).
The test
Simulation
is useful in order to check the numeric LED speed display but also for a
functional test of installed system extensions, as additional text displays, switches like opto-
couplers, relays or warn lights at a simulated vehicle, without the need to install and measure
on a road site with vehicle traffic. Further the made parameter settings defined in the parameter
sets, resp. their effects on the behavior of the numeric LED display can be simply tested.
After the test is called you are asked to enter a test speed and the number of the parameter set,
whose parameters shall be recognized for the simulation:
Test speed=51
Parameter set=1
<Quit with return>
The test speed value is compared with the speed threshold parameters defined in the parameter
set, resp. the threshold parameters of the
Settings
menu and the submenus
Thresholds Exten-
sions
and
Speed display options
, for the numeric LED display, the integrated LED circle
symbols, optional extensions and they are activated accordingly.
Only if the test speed in the range between set minimal and maximal speed displayed, see chap-
ter 6.3.4.2 the test speed is shown on the numeric LED speed display. By pressing the
<return> key the LED display and all system extensions are reset and deactivated.
The environment
Light sensor,
which measures the brightness of the environment, delivers for
a functional check a numerical result:
<Quit with Return>
Light sensor: 955
The result drops in bright sun light down to zero. In dusk, dawn and darkness the given results
are high and tend up to the maximal value 1023. In case the sensor value does not change de-
spite illumination e. g. with a torch or by dark covering, it is defective. The position of the light
sensor in the LED display board is approximately in the middle, right aside the hundred digit.
6.9 Data evaluation
The evaluation of measured speed data is done with the delivered software
viagraph
. The in-
stallation of the evaluation program viagraph is already described in chapter 6.1.3.
A detailed description of the evaluations you will find in the online help of the viagraph pro-
gram in the menu
