2.4.5 Set mode

Auxiliary set mode (Figures 2.2 and 2.3) is meant for veri cation and (or)

setting of the threshold DE (DER) values, DE and DE accumulation time reset.

Attention! To enter the “set” mode press and hold the LIGHT/SET button for about 5

seconds until the parameter to be set is  ashing.

To choose the parameter, press and release the LIGHT/SET button.

Press and hold the MODE button to rapidly change the parameter.

Press and release the MODE button to change the parameter to an exact setting.

Press and hold the SET button to exit the “set” mode or the dosimeter will

automatically exit set mode in approximately 90 seconds.

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  rst 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  rst

(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.
