6.1 Parameter P 02: Channel selection This parameter is only available in devices with two measuring channels (specification: 2xx). This parameter selects the measuring channel in programming mode. All further entries of parameters relate to the channel selected here. The green LED for CH1 and CH2, respectively, lights to indicated the selected channel. • Switching to channel 1: <+> ? CH 1 ?<P>, green LED CH1 lights • Switching to channel 2: <-> ? CH 2 ?<P>, green LED CH2 lights The channel can also be selected in measuring mode before starting the programming mode. 6.2 Parameter P 03: Transmission energy Settings 0001 ... 0009: Transmission energy steps This parameter specifies the energy content of the emitted ultrasonic pulse. The higher the transmission energy, the higher the energy content of the emitted ultrasonic pulse. 6.3 Parameter P 04: Gain Settings 0001 ... 0067: Gain steps The electronic circuitry amplifies the reflected ultrasonic pulse (echo) and then converts it into a digital signal (triggering). This parameter sets the strength of gain. The setting should preferably made with visual inspection by an oscilloscope connected to the test output (see chapter 4.3.2). If echo signals are detected, a little arrow appears in the top left corner of the display panel. One step changes the gain power approximately by 1 dB. The unit dB is a logarithmic, relative unit of measurement. For example, 20 dB are equal to factor 10; 6 dB to factor 2. Page 28
