Barograph:
Altitude can be read 0ff and stored to memory up to 8,000 metres. The interval at which altitudes are stored to
memory can be set at 5, 10, or 20 seconds.
(The “BaroPlus“ version has an additional cycle with intervals of 1 second which also registers speed for the
purpose of calculating rate-of-glide and showing polars).
A number of flights can be recorded. If the 20-second cycle is selected, the total flying time recorded in the
memory will be about 57 hours; this will be proportionately shorter if shorter intervals are selected. If the flight
currently being recorded over-runs the amount of memory capacity still available, the oldest figures recorded will
be automatically deleted to make room for the new data.
Markers can be set during the course of a flight which can later be recognized on the barogram as dotted lines.
Barograms can be printed out individually or as a package directly onto a battery-operated or mains—powered
printer. The fixed scale stretching up to 6,000 metres can be selected as the altitude scale, or which-ever scale is
best for showing the altitude graph in question.
PC software (Option):
Data can be administered and individual flights analyzed with the aid of a computer and the ,,Baromaster“ PC
soft-ware. The ,,BaroPlus“ software enables glide figures to be calculated and polars to be shown.
Log book:
Maximum altitude, flying time, greatest rate-of-climb and rate-of-sink, starting time and date (with year) of the last
10 flights are stored in the memory as are the highest readings for all flights, total flying time, and number of
flights. These readings can be seen an the instrument display.
Battery:
The PRIMUS works with two 9-volt Alkaline batteries. Battery voltage is shown every time it is switched on.
This is in the interests of your safety; Switching between the batteries 15 automatic if there is only one intact
battery in the unit, and if the voltage it is producing falls below 8.3V, the battery symbol will start to flash.
Bath batteries should then be replaced prior to the next flight.
Caution!
Duracell batteries should not be used because they are slightly too short and therefore do not exert enough
contact pressure. We recommend Japanese batteries or those from Varta or Philips.
