Inputting the DER (DE) threshold levels into the memory
This procedure can be performed in the DER (DE) measurement mode as well as in
of data transmission to PC mode. DER (DE) thresholds are input during DER (DE)
indication on the LCD.
Enter the set mode by pressing and holding the SET button (Figures 2.2, 2.3).
Input the first and then the second threshold levels. Exit the set mode. In data
transmission to PC mode it is possible to set an inhibit for changing the threshold levels
using the buttons. In case of exceeding the value of the first (second) DER (DE)
threshold, the dosimeter turns correspondingly into the DER (DE) indication mode and
noncontinuous (frequent noncontinuous) audible signal will sound. When the DER value
drops below the preset threshold, the audible signal will shut off. Press any button to
silence the alarm sound. The audible signal will shut off automatically in approximately
60 seconds, the repeated audible signal will sound in approximately 4 minutes.
2.4.6 Number indication mode
In number indication mode the following items appear on the LCD:
- the instrument’s number on a display (Figure 2.1, Item 2);
- year (Figure 2.1, Item 4) and month (Figure 2.1, Item 3) of production.
2.4.7 Data transmission to PC mode
2.4.7.1 The instrument allows storage and transmission to PC of DE history
(hereinafter "history"), DER accumulation, events of exceeding the preset DE and DER
threshold values, event of DE reset trough IR communication channel using the buttons.
Selection of the events to be stored in the history, and frequency of these recordings is
performed using software. History data are inaccessible without IR adapter (internal or
external).
The instrument performs data transmission to PC under the software program “System
of Data Collection and Processing for the 1621/ 1603/ 1604 Devices” through the IR
communication channel adapter compatible with IrDA interface.
Minimum computer system requirements:
- Pentium 100;
- 32 Mb RAM;
- monitor resolution 800 x 600;
- IR adapter (internal or external);
- OS Windows 98/2000/XP;
- printer.
2.4.7.2 To use the dosimeter in data transmission to PC mode:
- Read and follow the recommendations of the file Read_me.doc on the CD supplied
with IR adapter;
- Read the help file Help_ 1621.doc;
- Connect the adapter of IR communication channel to a PC COM port;
- Install the IrDA communication unit and switch on the IR connection;
- Install the program “System of Data Collection and Processing for the
1621/1603/1604 Devices” from the CD, (run the program \DISK1\SETUP.EXE);
- Run the program 16XX.EXE;
- Read the help section of the program “System of Data Collection and Processing for
the 1621/ 1603/ 1604 Devices”;
- Orient the dosimeter and adapter of IR communication channel of the PC by placing the
dosimeter at a distance of 10-20 cm from the IR channel adapter;
