Instructions:
1. Work Mode Description:
Wearable (watch type) personal dosimeter can be divided into standby, measurement, set three modes of operation.
A. Standby mode: Standby mode is power saving mode. You can query the measurement result, alarm threshold and other parameters by pressing the key.
In this mode, press 【RESET】 key to check the measurement result, alarm threshold and other parameters. Press 【MODE】 key, LCD display "on X", where X said the number 3,2,1,0, two seconds followed by the display, after the buzzer sound twice, backlight flash once, the instrument switch to the measurement mode, If the [MODE] key is pressed and held for less than 3 seconds, the instrument automatically returns to standby mode;
B. Measurement mode: measurement mode real-time monitoring of radiation levels. In this mode, the timing of the acquisition count, Every other period of time to calculate and data processing, if the measurement results exceed the preset threshold, the sound and light and LCD alarm.
Short press 【MODE】 to switch the display (dose rate / cumulative dose / working time). Press 【MODE】 key, LCD display "oFF X", where X said the number 3,2,1,0, two seconds followed by the display, after the buzzer twice, LED flash once, the instrument switch to standby mode, If the [MODE] key is pressed and held for less than 3 seconds, the instrument automatically returns to the measurement mode;
C. Parameter setting mode: Set the dose rate, cumulative dose, working time alarm threshold and other parameters by pressing the key.
[Note]: Press and hold the button for 2 seconds or more.
2. Standby mode operation:
When the dosimeter is in standby mode (not measured), the LCD displays the current time.
To view the alarm threshold and parameters: Press the [RESET] key briefly to toggle the displayed measured values and parameters. The display order is: maximum dose rate and its relative time → cumulative dose and working time → dose rate alarm value → cumulative dose alarm value → working time alarm value → cumulative dose clear mode → return to standby mode.
3. Measurement mode operation:
Turn on the operation: long press 【MODE】 key, until the LCD shows the dose rate, enter the measurement mode.
Measurements can be switched in three states: dose rate, cumulative dose and working time. Each time the mode key [MODE] is pressed, the display status is changed once. The order is: dose rate → cumulative dose → working time → dose rate, Loop appear.
The alarm conditions that may occur during measurement are as follows:
① dose rate over the threshold, in addition to display the dose rate flashing and R symbols, but also shows the alarm symbol , while sound and light alarm.
② dose over the threshold, in addition to display the dose value flashing and D symbols, the display alarm symbol , while sound and light alarm.
③ working time timeout, in addition to display time value flashing and clock symbols, the display alarm symbol , while sound and light alarm.
④ When the detector fails, the LCD displays the symbol "dEtF" and flashes, and the sound and light alarm.
4. Parameter setting mode operation:
To enter setup mode: In standby mode, press and hold the [RESET] key until the LCD displays "SET", indicating that the parameter setting mode is entered.
Set the operation: In the setting mode, the current flashing digit is settable, press 【START】 key to increase the bit; short press 【MODE】 key to move to the next bit to set; short press 【RESET】 key to switch Display the next parameter to be modified, the parameter setting order is:
Exit the setting mode: In the setting mode, long press 【RESET】 key to return to the standby mode, indicating that the parameter setting mode has been exited and the saved parameters are saved automatically. In the setting mode, 60 seconds without any operation automatically exit to standby mode.
5. Dose rate alarm threshold setting:
The dose rate, dose threshold parameter setting format is exponential, ie X.Y*10^n.
When entering the dose rate alarm threshold setting mode, the LCD's "Rate" and "" are displayed. The unit is μSv / h, the setting range is 1.0*10^0 ~ 9.9*10^4, that is, 1μSv/h ~ 99000μSv/h.
For example, suppose the dose rate threshold is adjusted from 180μSv / h to 10μSv / h, as follows:
(1) In the standby mode, press the [RESET] key and hold for more than 1s until the buzzer sounds and the LCD displays "SET" and enters the parameter setting mode. First, the LCD displays the dose rate alarm threshold "1.8 2" (ie 1.8*10^2μSv/h), the number "1" flashes;
(2) "1" does not need to change, short press 【MODE】 key to move to the next bit, the number "8" flashes, short press 【START】 key twice, the number "8"
(3) Short press 【MODE】 key to move to the last bit "2", and "2" flashes, short press 【START】 key five times, the last digit becomes "1", the LCD displays the three digits "1.0 1", that "1.0*10^1", that is, to set the dose rate alarm threshold 10μSv/h;
(4) If you want to modify other parameters, press 【RESET】 key to enter the next parameter (cumulative dose alarm threshold). If the current parameter is not set, press 【RESET】 key to switch to the next parameter setting until the required parameter setting carry out.
(5) If you do not need to set other parameters or all parameters set to complete, long press 【RESET】 key to exit the setting mode to return to standby mode, while saving the set parameters.
6. Cumulative dose alarm threshold setting:
When entering the cumulative dose alarm threshold setting mode, the LCD symbols "Dose" and "" are displayed. The unit is μSv, the setting range is 1.0*10^0 ~ 9.9*10^6, that is, 1μSv ~ 9900000μSv. Set the same dose rate alarm threshold setting.
7. Working time alarm threshold setting:
When entering the working time alarm threshold setting mode, the LCD symbol "Time" and "" are displayed. Parameter setting format is hh: mm, the setting range is 00: 05 ~ 99: 59, that is, the maximum working time alarm value is 99 hours 59 minutes.
If the working time alarm is set to 00:00, cancel the working time alarm function.
8. Time setting:
The time setting includes the year, date, and current time settings.
9. Charging operation:
When the dosimeter LCD display undervoltage or no display, please promptly charge operation.
The charging port of the dosimeter is a Micro USB interface. Connect one end of the Micro USB cable to the dosimeter and the other end to the charger or the USB port of the computer. After entering the charging state, the LCD displays the battery symbol to slide.
10. Communication operation:
With the special communication software, the measurement data of the dosimeter is read out on the computer for storage for further analysis and processing.
First connect the hardware, the Micro USB cable connected to one end of the dosimeter, the other end connected to the computer USB port. Install the dedicated communication software on your computer and turn on the software.
Daily maintenance:
1. Charging batteries:
When the undervoltage symbol appears or the LCD is not displayed, the battery charging operation must be carried out. When the instrument is not used for a long time, charge and discharge should be carried out every 100 days.
Battery Specifications: Rechargeable lithium battery (3.7V, 140mAh).
2. Storage:
After the instrument is used, it should be set to standby.
Storage conditions: Temperature: -10 ~ +50 ℃, relative humidity: ≤90% (no condensation).
