exceeds 2999 s, the symbols “- - -” are indicated on the LCD), coefficient of variation in
percents.
If the measured DER value is over the upper limit of the DER indication range (6.5
Sv/h for the РМ1603A and 13 Sv/h for the РМ1603B), the LCD will show the overload
symbol “OL” and non-continuous audible signal will sound.
In the DER mode the collected statistics of DER measurement can be reset and the
process of measurement can be reactivated by simultaneous pressing of the SET+MODE
buttons.
2.4.3 DE indication mode
In the DE mode (figure 2.1) the following parameters are indicated on the LCD:
- DE (µSv, mSv, Sv);
- DE accumulation time.
DE and DE accumulation time reset is possible in the set mode by simultaneous
pressing of the SET+MODE buttons (figure 2.2).
In the mode of data transmission to PC it is possible to set an inhibit for DE reset using the
buttons.
There are two method of measurement of the DE accumulated over a certain period of
time.
The first method (recommended). In the beginning of measurement the DE should
be reset using the keys or the PC and the user software supplied on CD. Then the dose
displayed at the end of the period will be the dose accumulated over the period of
measurement.
The second method. The dose value in the beginning of the period of
measurement should be deducted from the DE value displayed at the end of the period.
2.4.4 Set mode
Auxiliary set mode (figures 2.2, 2.3) is meant for verification and (or) setting of the
threshold DE (DER) values, DE and DE accumulation time reset.
To enter the “set” mode press and hold for about 5 s the SET button and the
parameter to be set will be flashing.
To chose the parameter press and release the SET button.
To change the set parameter:
- rapidly – press and hold the MODE button;
- for exact setting – press and release the MODE button.
The dosimeter will exit the “set” mode by pressing and holding the SET button or
automatically in approximately 90 s.
2.4.5 Inputting the DER (DE) threshold levels into the memory
This procedure can be performed in the DER (DE) measurement mode as well as in
the mode of data transmission to PC. DER (DE) thresholds are inputted during DER (DE)
indication on the LCD.
Enter the set mode (figures 2.2, 2.3).
Input successively the first and then the second threshold levels.
Exit the set mode.
In the mode of data transmission to PC it is possible to set an inhibition for changing
the threshold levels using the buttons.
