2.2.4 Switching the dosimeter OFF
To switch off the dosimeter, enter "SETTINGS", press "NEXT" to go to "POWER OFF"
and press "SELECT", then press "YES" to confirm (Figure 2.4).
Figure 2.4
2.2.5 DER measurement mode
The dosimeter enters the DER measurement mode ("DER") automatically upon power on.
In this mode the dosimeter can measure:
- DER of continuous photon radiation;
- average DER of pulsed radiation.
2.2.5.1 Measurement of continuous photon radiation DER
While in the DER measurement mode ("DER") the dosimeter’s LCD indicates continuously
measured DER values of photon radiation in "Sv/h", "mSv/h", "Sv/h", statistical uncertainty of
DER indication in percent with 0.95 probability, status of the rechargeable battery (icon) and
current time in hours and minutes (Figure 2.5).
Figure 2.5
The DER values can be read when the statistical uncertainty is 15 % and less.
Attention! Please remember that the lower the statistical uncertainty is, the more
accurate the measurement result is.
It is possible to re-start DER measurement in this mode. Press "START", then "1" button
(line "1 – DER") and the current DER value will be zeroed and the measurement will re-start.
The dosimeter monitors two settable alarm thresholds for the DER (2.2.7.5). When the DER
alarm threshold (Threshold 1 or Threshold 2) is exceeded, the dosimeter goes to the DER
measurement mode, indicates "THRESHOLD 1" or "THRESHOLD 2" on the upper line and
triggers enabled sound (intermittent signal for threshold 1 and rapid intermittent signal for threshold
2), light and vibration alarms (2.2.7.6). Press any key to switch off the alarms. The alarm is
triggered again when the DER level becomes lower than one of the thresholds and threshold 1 or
threshold 2 is exceeded again.
If the DER indication range is exceeded, the dosimeter triggers an alarm and the LCD
indicates "OVERLOAD" and value 12.0 Sv/h.
2.2.5.2 Measurement of average DER of pulsed radiation
It becomes necessary to measure average DER of pulsed radiation when the user is exposed to
pulsed photon radiation at pulse duration more than 1 ms.
Measurement of average DER of pulsed radiation can be started from the DER measurement
mode. Press "START", then press button "2" (line "2- AVERAGE DER OF IMP EXPOSURE"), the
DER values will be zeroed and the dosimeters will start measurement of average DER of pulsed
radiation ("AVERAGE DER") (Figure 2.6).
The average DER of pulsed radiation can be read when statistical uncertainty is 15% or less.
Measurement of the average DER can be continued for unlimited time to reduce statistical
uncertainty for more accurate results. Press "BACK" to exit the average DER measurement mode.

15
When the dosimeter is moved to another place, re-start measurement of the average DER of
pulsed radiation for more significant readings.
Attention! The dosimeter writes the values of average DER of pulsed radiation into its
operating history. The dosimeter monitors two settable alarm thresholds for the average DER
of pulsed radiation.
Press "BACK" to exit the mode of measuring average DER of pulsed radiation.
Figure 2.6
2.2.6 DE measurement mode
The DE measurement mode is used for the measurement of continuous and pulsed photon
radiation (pulse duration not less than 1 ms).
Press "NEXT" in the DER measurement mode to enter the DE measurement mode ("DE")
"NEXT", Figure 2.7.
Figure 2.7
In this mode the dosimeter’s LCD indicates measured DE values in "Sv", "mSv", "Sv",
time of DE accumulation in hours (H) and minutes (M), status of the rechargeable battery (icon)
and current time in hours and minutes (Figure 2.7).
It is possible to reset (zero) the DE and DE accumulation time values using the buttons in
the "SETTINGS" mode. Enter "RESET DE": \"SETTINGS"\"THRESHOLDS"\"DE"\"RESET DE"
and press "YES". The DE reset event and the reset DE value is recorded in the dosimeter’s
memory.
The dosimeter monitors two settable alarm thresholds for the DE (2.2.7.5). When the DE
alarm threshold (Threshold 1 or Threshold 2) is exceeded, the dosimeter goes to the DE
measurement mode, indicates "THRESHOLD 1" or "THRESHOLD 2" on the upper line and
triggers enabled sound (intermittent signal for threshold 1 and rapid intermittent signal for threshold
2), light and vibration alarms (2.2.7.6). Press any key to switch off the alarms. The alarm is
triggered again when the DE is reset or after setting higher threshold 1 or threshold 2 and DE
threshold is exceeded again (threshold 1 or threshold 2).
If the DE indication range is exceeded, the dosimeter triggers an alarm and the LCD
indicates "OVERLOAD" and value 12.0 Sv.
When the “DATA” button is pressed, the dosimeter will display dose equivalent value and
date (dd/mm/yyyy) when dose accumulation has started:
When the “TIME” button is pressed, the dosimeter will display the time (dd/hh/mm) left until
the first dose equivalent threshold is exceeded as shown on the picture below:

16
