STEP OD-02 Technical Description And Operating Instructions page 16

If the wall reinforcement cap (5) is removed, the indicated measuring value at dose
equivalent measurement corresponds to
equivalent measurement. Both measurement units are indicated on the display:
Optional OD-02 Hx:
In countries which have not introduced metrics regarding ICRU- Directive, the
measurement unit is the photon dose equivalent / - dose rate:
The large energy range of dosimeter required the use of wall reinforcement cap in
dependence of radiation type and energy:
Radiation
X-Ray and Gamma

Beta radiation
The measured unit of OD-02 Hx is shown in first line of display:
Caution!
The entry windows of the soft radiation chamber are sensitive to mechanical
stresses!
After measurement completion, the acrylic plastic shielding must be refitted
on the probe and the device must be switched off.
Note:
Measurements in electromagnetic fields, e.g. next to mobile phones, etc.
must be avoided because these may influence the measuring results.
