Instructions for use
VF1807090083 EN revision 37
6. Instructions for use
If the instrument is turned off, turn it on according to Chapter 5.6.1.
6.1. Visual and acoustic signalization
Various phases of measurement, operating instructions and measurement evaluation are communicated
visually to the user by means of the PLC display and two indicator lamps as well as acoustically by means of
voice messages.
During the contamination measurement of clothing (or other objects) using the frisker, an intermittent acoustic
signal is heard indicating registered pulses. The intensity of acoustic signalization (signal repetition rate)
corresponds to the pulse rate detected, i.e. “faster beeping” indicates higher detected rate.
