ECOTEST MKS-UM Operating Manual page 16

1.2.10 The dosimeter is powered from lithium-ion battery of 26650 size with
an integrated protection board against overcharging, prevention of discharge and
short-circuit. Battery rated voltage – 3.7 V, capacity – 4000 mAh.
1.2.11 The dosimeter warns of the battery discharge.
1.2.12 The battery can be charged from:
- AC mains from of 220V voltage, frequency of 50 Hz;
- vehicle network with DC voltage from 9 V to 32 V.
What is more, the battery can be charged from the solar panel.
1.2.13 The dosimeter ensures measurements if influenced by:
- ambient air temperature from – 30 to + 55
- relative humidity up to 95 % at 35
Note. For operation in the temperature range from minus 21°C to minus 30°C, the
dosimeter must be switched on at a temperature not lower than minus 20°C, or be powered
by an external power source (power supply unit 220 V / = 12 V or a vehicle battery).
- atmospheric pressure of 84 kPa up to 106.7 kPa;
1.2.14. The dosimeter is proof against N1 group sinusoidal vibrations with a frequency
from 10 Hz to 55 Hz, with an offset amplitude for a frequency lower than 0.15 mm transition
frequency.
1.2.14 The dosimeter remains operable after the influence of the following
external factors:
- maximum low temperature –40
- maximum high temperature +60
- photon-ionizing radiation with DER of 100 Sv/hour during a 5-minute
exposure of the control unit, and 100 Sv/hour during a 50-minute exposure of the BG
probe, 100 Sv/hour during a 10-minute exposure of the ABG probe.
