The instrument can operates as an acoustic Dosimeter, which function is supplementary to the Level Meter
function. In the Dosimeter mode, basic dose results (DOSE, D_8h and LAV, E, E_8h) are calculated in parallel
with the Level Meter results for channels with the Sound inputs.
11.1 SELECTING DOSIMETER FUNCTION
To select the Dosimeter function, open the
Measurement Function screen, select the
Dosimeter item, mark it with the ► key and
press <ENTER>.
Note: It is not possible to change the current function while a measurement is taking place.
In this case the instrument displays for about 2 seconds the text ”Measurement in Progress”. In
order to change the current measurement function the instrument must be stopped!
11.2 SELECTING DOSIMETER PARAMETERS – DOSIMETER SETUP
The Dosimeter Setup is accessible in the
Input when the acoustic Dosimeter function is
selected.
The Dosimeter Setup consists of the
parameters, which influence the calculation of
the dosimeter results: Exposure Time,
Criterion Level, Threshold Level and
Exchange Rate (the definitions of the
dosimeter results are given in App. D).
The Exposure Time position enables the user to set the desired value of the
exposure time that is used for the calculation of different Dosimeter functions
as well as LEPd that is also calculated in the Level Meter mode (cf. App. D for
the definitions of the functions). The Exposure Time values are within the
range [00h01, 08h00].
The criterion sound level influences the calculations of the DOSE and D_8h
results. The Criterion Level line is accessible after pressing the ▲, ▼ key in
the Dosimeter Setup list. The available values are as follows: 80 dB, 84 dB,
85 dB or 90 dB.
