7.2 Technical data
7.2.1 Nominal rating of the 11-R model series
-Battery: 11.1VDC/4.4Ah, fully charged for 4-8 hours of continu-
ous operation, depending on the operating conditions;
-18VDC power supply (U
out
): 1112C, 100-240VAC (U
in
) , 47-
63Hz, 2.5 A (output)
Maximum current Mini-LAS:
Battery discharged 1.2A
Battery fully charged 0.45A
1000 m. 2000 m with individual readjustment of the volume flow
per terminal programme with the help of a volume measuring
device, e.g. Drycal or Gilibrator.
Temperature range (in operation):
+4 to +40 °C, relative humidity < 95 % (non-condensing)
Temperature range (storage and
transportation):
-20 to +50 °C, relative humidity < 90 % (non-condensing)
Maximum relative humidity (in
operation):
Relative humidity < 95% (non-condensing)
Maximum relative humidity (stor-
age and transportation):
Relative humidity < 90% (non-condensing)
Temperature of the sample air:
+4 to +40 °C, relative humidity < 95 %, nor corrosive or explo-
sive gases
Pressure range of the sample air:
At normal pressure the volume flow is set to 1.2 litres per mi-
nute.
For sites more than 1000m above sea level, the volume flow
should be readjusted.
0 to -50 hPa (short term). At overpressure (max. +100 hPa) and
for extended measurements with higher underpressure (max. -
100 hPa), the sample air return has to be used.
