if measured rate of

duration would be switched on to signalize rate of

such case maximal possible value of 42.9 Sv/h would be indicated;

when the accumulator battery voltage is below 3,52 V, the blinking battery symbol

would be indicated to prevent that the dosimeter will be automatically switched off

in few hours because of the complete power discharge; in such case 2 second sound

signal would be given each 15 minutes. In case of 3,3 V battery voltage, the switching

off signal will be given and the dosimeter will be automatically switched off with the

preservation of accumulated information in the memory. In case of dosimeter operation

under negative outside temperature around minus 20 °С, the battery discharge symbol

can be also indicated for almost charged battery. In such case the automated switching

off will occur after 24 hours of continuous operation at least.

automatically increased for the decreasing dose rate. Each sequential calculation of rate of

value is accompanied by sound signal of 60 ms duration.

Dosimeter power supply is provided by three accumulator batteries of no less than

280 mA/h capacity each with the total supply voltage of less than 4,2 V. Continuous operation

without battery charge is 100 hors for routine operation of the sound signal: less than 1 sound

signal of measurement per minute. Battery charge is provided by КЗУ-27 charger included in the

shipment set.

For dosimeter operation in the dosimetry monitoring system together with PC, the data

transmission is arranged via УС-05С.

1.5 Marking and sealing

1.5.1 Following marks are placed on the casings of dosimeter components:

trade mark or name of the manufacturer;

conditional sign of item: item type and unit;

sequential number of item according to the manufacturer;

year of production;

approval sign of measuring instrument pattern (only for the dosimeter);

power, voltage/current and electric power frequency;

protection degree on ГОСТ 14254-96.

1.5.2 The place and technology of marking and font size agree to requirements specified

in design documentation.

1.5.3 The dosimeter, УС-05С and КЗУ-27 must be sealed according to design

documentation.

1.6 Packing

1.6.1 Dosimeter packing should be done according to the requirements of category КУ-3

on ГОСТ 23170-78.

1.6.2 Inner package of the dosimeter, УС-05С and КЗУ-27 should correspond to the

requirements of ГОСТ 9.014-78 for group III of ВЗ-10 protection type, ВУ-5 package variant.

Protection term without re-conservation is 3 years.

1.6.3 Packing should be carried out indoors in the ventilated rooms under the air

temperature of +15 to +40 °С, relative air humidity of up to 80 % at +20 °С, and air

concentration of corrosion agents according to type I on ГОСТ 15150-69.
