2.4 Adjustment
2.4.1 Change of battery type
To change the battery type, turn on the dosimeter while holding the
message "SELECT THE TYPE OF BATTERY" and currently used battery type will be shown on the
display. Use
and "MODE" buttons to select the desired type; confirm selection by pressing
"START" button in this mode; after that the dosimeter will switch over to the working mode. Use
button to exit the selection mode. At that, the dosimeter will switch over to the working mode and the
previous type of batteries will remain unchanged.
2.4.2 Change of the confidence probability value (predetermined reliability)
To change the value of confidence probability, switch over to the engineering mode. For that,
turn the dosimeter on while holding the
A request for entering the access code will appear on the display. The code is as follows: "START"->
"MODE"-> "MODE"-> "START"-> "START". Use
value. Use "START" button to confirm or
off. Turn the dosimeter on, make sure that required value is set (see symbol in the message line).
2.4.3 Correction of adjusting coefficients
Adjusting coefficients are set by manufacturer and can be changed only during repair or
calibration in the engineering mode.
2.4.3.1 Alternative assignment of controls
Alternative assignment of controls in the engineering mode is presented in the Table 2.4.
