1.4.1 Design of the radiometer
The radiometer (in accordance with Figure 1.2) is designed as a rectangular
parallelepiped rounded on each side. The plastic damp- and dustproof body of the
radiometer (ingress protection rating IP54, category 2) consists of two parts – upper
(1) and lower (2) covers. The LCD (3), ALARM light-emitting diode (4) and the
keys of control (THRESHOLD (5), MODE (6), γ/β/α (7), SAVE (8), SOUND (9))
are located on the panel of the upper cover. The printed-circuit board with the
electric circuit of the device is screwed with four screws to the upper cover of the
radiometer. All inscriptions of the upper cover are screen-printed.
