The converter can be used in two different modes:
q
with continuous sampling
q
with sampling to preset unit of time.
q
CONTINUOUS SAMPLING (pic.1) (ENERGY SAVING OFF)
In this mode the converter make the measure in accordance with the classical diagram of the
flow meter; the consumption of the system, with any diameter of the sensor is 0,05 W ; the
life of battery is about 1 month (6 with 6 battery)
The accuracy of the system is definite in those conditions.
q
SAMPLING TO PRESET UNIT TIME ( pic. 2 ) ( ENERGY SAVING ON )
This mode works sampling the range to intervals of preset time (see MEASURE menu, func.
3.5); it allows a great saving of energy
In this conditions the consumptions are:
Sampling
time (s)
Battery life - n° 1
battery (years)
Battery life – “ N “
batteries (years)
1 0,7 0,7 * N
2 1.3 1.3 * N
5 2.1 2.1 * N
10 2.7 2.7 * N
15 3.0 3.0 * N
>= 30 5 5.0 * N
Whatever the results ,
the maximum time is
limited to 10 years

ATTENTION: the consumptions on the table are without optional IF2 cable connected to the
converter. This device accelerate the consumption of the batteries even if the instrument is in standby
mode . Recommends to disconnect the IF2 cable from the converter after every his uses or
switch off the converter by the dip-switches (see page 9 )
